March 4.5-28x52 High Master Review and Comparison to Tangent Theta 5-25x56 Page 4

RETICLE & ILLUMINATION
One of the most important choices one can make in a long range scope today is the reticle, this is, after all, what you will see every single time you bring the scope to your eye so it’s important to make sure that it fits the needs or your shooting style. That being said, reticle selection or preference is extremely subjective and saying Brand X reticle is “the best” is like saying “Brand X vanilla ice cream is the best” – we all have different tastes, and the good news is that there are many options available to the long range community. With this in mind, my ratings below should be taken with a grain of salt because they are based on MY preference, but I will explain what I like and why, which should help you understand if it might be something you would like or not like even though I may have a differing opinion.
Reticle & Illumination Assessment criteria (rating 1-10 with 1 being worst and 10 being best):
Reticle Usability – Tie: March – 10 | Tangent Theta – 10
The reticle in the March is their new FML-TR1, which is a superb design created by none other than the Dark Lord of Optics himself. The reticle provided in the Tangent Theta is their Gen 3XR design. Both are a newer .2 mil hash design with dots in the Christmas tree, which I prefer, because they do not obscure the image as much as the solid lines of some other tree designs. One of the interesting features of the FML-TR1 is that the Christmas tree dots virtually disappear when you’re not using them, they blend into the background. The Gen 3XR also does a decent job at this but not to the level of the TR1. A feature shared in both designs are the larger center dot, in a trend by many manufacturers to make the tiniest center dot possible, I find myself constantly searching for this dot, especially on dark backgrounds, but that does not happen with the FML-TR1 and Gen 3XR which both use a .075 mrad dot. The FML-TR1 adds a .075 mrad center cross to complement the dot, this cross is .2 mrad wide and is spaced .2 mrad from the center dot and main stadia making it very easy to measure without clutter, the Gen 3XR has large dots every full mrad mark in both horizontal and vertical stadia. When I first saw the specs for the reticle, I was worried the center would be too thick, but it is ideal in my book offering the perfect balance and allowing it to be usable even at low magnification.
Illumination Color and Brightness – Advantage March: March – 7 | Tangent Theta – 6
Both scopes offer red illumination as the only option. Tangent Theta has lackluster performance when it comes to brightness, but sufficient for low light engagements. March has improved on previous performance but still does not deliver a daylight bright illumination out of their 6-setting module, although it too is sufficient for low light situations. I would say the March is ever so slightly brighter than the TT illumination. March did not exhibit illumination bleed while the Tangent Theta’s illumination did show slight bleed on full power but not enough to be distracting.
Overall Reticle & Illumination Assessment – Advantage March: March – 17 | Tangent Theta – 16 (20 points possible)
Neither of these scopes’ illumination modules are going to wow the user for usability during daylight hours. Scopes like Kahles and ZCO both offer much brighter illumination so if you are a shooter who likes to have the little extra during the day you may be somewhat disappointed. That being said, illumination in long range scopes is typically relegated to lower light situations and that’s where the March and Tangent will perform adequately.

ERGONOMICS
Overall Ergonomic Assessment – Tie: March – 8 | Tangent Theta – 8 (10 points possible)
Tangent Theta excels with the traditional design in long range scopes, clearly, they are regarded as some of the best glass and mechanics with superb fit and finish that is virtually unmatched by any scope on the market. Tangent includes the excellent Tenebraex caps and ARD which is a very nice touch; however, I do wish the Tenebraex caps would lay flatter when opened. Tangent could use larger numbers on their turrets while the March could use a better illumination control module. March has the large elevation shroud and includes flip caps, throw lever and sunshade for those who desire those features, March turrets are also low profile while Tangent’s are some of the meatiest out there. March offers greater magnification and FOV while reducing size and weight considerably. The overall ergonomic winner is a tie, the March has an advantage with its short body and the Tangent has an advantage with the toolless turrets.

FIT & FINISH
Overall Fit & Finish Assessment – Advantage Tangent Theta: March – 8 | Tangent Theta – 9 (10 points possible)
As good as the March is in overall craftsmanship, and it is superb… the best I have seen from Japan, earning it a spot in the ranks of alpha class scopes that are dominated by European craftsmanship, I do have to give the nod to Tangent Theta with overall fit and finish. Quality reeks from this scope everywhere you look, the precise fit of every single part abounds with the precision that Tangent Theta is known for. All that being said March has their own set of impeccable craftsmen (and women) who are hand assembling each and every scope, if Tangent Theta gets a 9 then March is not far behind with an 8, we are truly splitting hairs when it comes to the fit and finish of each of these scopes – as it should be with the alpha class.
PRICE
Overall Price Assessment – Advantage March: March – 7 | Tangent Theta – 5 (10 points possible)
Most knowledgeable shooters are aware that the alpha class of sport optics is not cheap, you are guaranteed to pay in the thousands for these top-quality optics, but the March and Tangent Theta scopes really push the wallet to the limit. MSRP for the March comes in at a teeth grinding $3590 while the Tangent Theta is a “do I really need two kidneys’” - $4800! Street price you can expect to pay less but not much less.
Final Score – Advantage Tangent Theta: March – 226.6 | Tangent Theta – 239.8 (out of 270 possible points)
It should come as no surprise that Tangent Theta takes the blue ribbon in this competition, but the March has proven to be a confident runner up. This was kind of an “unfair” comparison to begin with as we are comparing one of the best scopes on the market today to a new comer that is designed to push the limits what can be done in a short body design. The final results are very close and I could easily see any one shooter choosing one scope over the other. At the end of the day the March has so much going for it: less expensive, shorter, lighter, more ergonomic with very nice turrets, High Master glass with amazing color/contrast with an industry leading FOV (for its magnification range). The Tangent Theta bests the March in several areas including overall resolution, edge to edge sharpness, overall fit and finish, eyebox and DOF. If the features of the Tangent Theta suit your fancy more than March you won’t find an argument from me, but I highly recommend you give the March a chance especially if you're looking for a scope that packs so much into a shorter/lighter design, I think you will be pleasantly surprised and at over $1200 less, your wallet will be thanking you as well.

Areas of Improvement
March
The first item that comes to mind is for March to design non-translatable turrets, that is - turrets that do not rise and fall as you spin them up or down. I would also like to see a similar locking turret design with larger diameter turret as is on the 5-42x56 HM. Get an illumination module like so many other new scopes that have excellent low light quality with no bleed but also bright enough to be used when the sun is out, and a different design for easier manipulation of settings especially if wearing gloves.
Tangent Theta
Get a daytime bright illumination module. Larger and more bold numbering and dashes on the turrets, maybe even reduce the height of the turrets. Reduce spacing on turrets to 12 mrad per rev and increase the travel to 36 mrad total. This design which originates from Optronika could use an optical formula face lift, maybe something like a shorter bodied 5.5-33x56 with a wide angle eye piece – how many shooters would turn their heads if TT came out with a completely new scope and not something they essentially inherited from Premier Reticles? My final comment is for Tangent to invest in better multi-coating to help eliminate flare when the scope is pointed towards the sun, depending on position there can be significant flare and ghosting which shouldn’t be there at this price point, sure you can put on the ARD to help eliminate this, but many will not be using that part for most of their shooting.
How does the March compare to Brand X?
Often when I do these reviews, I get asked the question, “how does it compare to insert favorite brand/model here” and while I’ve gone through a number of alpha class scopes I simply do not have the money or time to try them all. What I can tell you is I did a brief comparison of the 4.5-28x52 HM with a ZCO 4-20x50 and with the updates that March has made to the final (production) version I can confidently say the March gives the ZCO a run for the money. At about the same price, the March offers a scope that is slightly smaller than ZCO’s ultra short but with magnification and FOV that bests both of ZCO’s offerings (the 4-20 and 5-27). If you told me that you want the absolute best in optical/mechanical performance then I would tell you to buy the ZCO, but if you want both scopes wrapped up in one body and with greater FOV and arguably better crossover style reticle then the March 4.5-28x52 should be on your radar. The March is a scope that will be as at home on a competition rifle, a short barreled rifle like a Desert Tech, an AR platform and a hunting rifle, it may well be the most well rounded crossover scope available today which says a lot given the competition that is out there. If there is another scope you’d like me to compare to the March then send me a PM and I’ll send you my address and you can ship it to me and I’ll do a side by side evaluation 😉
Final Thoughts
Finally, reiterating what I mention at the very beginning, I am biased (we all are) and I have my own preferences and this review and opinion has influence from that, hopefully I’ve done an adequate job throughout the review to share where my personal preference comes into play in order to help you better evaluate a particular feature. I might rank a reticle as a 10 but you would rank the same at a 7. Also, I am trying out this new “scoring” system based on something Frank brought up during 2020, I am not sure how I feel about it as so much of the ratings are subjective so I welcome your constructive feedback on how I can improve or simply get rid of it entirely.
Where can you find March scopes, the good news is that since 2020 more and more dealers have begun carrying them. Keep in mind March are handmade scopes and lead time is running 45-60 days, I tried to get March to agree to a Group Buy for the Hide but they did not want to undercut other dealers so for now you will need to contact a March dealer.

Vortex Defender XL Green

This is the second time Vortex' Defender XL crosses my path. I was very impressed with the original red dot version, so I was curious to see how the one with the green dot works for my eyes.
To get the details, see the attached video.
The cliff's notes version is that I am just as impressed with this one. In terms of collimation quality and parallax control, it is quite exceptional.

Primary Arms HTX-1 US Made red dot sight

I've had this RDS for a bit over two months now and I am beyond pleased with it.
Despite some spirited abuse, it keeps soldiering on.

It is a very nice RDS and being fully made in the US does not hurt either.

Delta Stryker 3.5-21x44 Wrap-up

This scope comes up a lot since I really like the configuration. It is time to do a final wrap-up of it.

It is one of my favourite scopes on the market today, especially for the money, since I naturally lean toward general purpose-ish designs. Still, while the 3.5-21x44 Stryker is relatively compact and light, it still clearly leans toward the precision side of things, which suites me very well.

Updates, deals and new review items: PLxC RDB, Zeiss Tripod, etc

As the week is coming to an end, I find myself in an unusual place: home.

I plan to be home between now and September 1st when I have to go to Israel for ten days, returning on the 11th (dayjob stuff).

For the last couple of months, between family vacations, work and a couple of matches, it seems like I only spent enough time at home to check zero on my 6.5CM Fix and head out again (it has not shifted, thank you Area 419 mount).

I have a lot to do during the next two weeks, but I will try to take some pictures, film some footage and release it as I go along. I can edit videos on the plane or in Israel just about as well as I can at home.

While generally, I am very picky about what I accept for review (given my bandwidth limitations), I do have a few new things here worth talking about.

One is Primary Arms new PLxC RDB 1-8x24 LPVO. It is essentially a version of the original FFP PLxC LPVO except with different reticle illumination technology. The new model utilizes diffractive reticle illumination (same style ...

Steiner C35 Gen2 Mount
from Annex Defense

The production version of the Annex Defense's mount for the Steiner C35 Gen2 thermal Clip-on is finally here.  At $1600 (when this is published), the clip-on is an absolute steal.

I've had it for a few days, but, me being the good old paranoid me, I spent some time shooting with it before posting anything.  I had a couple of days with it prior to last weekend's match in Montana and a couple of days after.  Another to pop it on and off a few times and get a couple of hundred rounds of 6.5Grendel through the gun to see if anything shakes loose.  So far so good.

The C35 Gen2 clip-on is sitting on my 6.5Grendel AR as a part of a long running "Only One" project that I have.  It pairs perfectly with the Steiner H6Xi 2-12x42 scope.

Here is what comes in the box from Annex Defense:

The order in which the whole thing comes togethe is pretty stragihtforward:

-slide the thermal washer onto the threaded interface extending out of the back of the clip-on

-spin the mount itself onto the threaded interface (the mount is threaded on the inside) until it can go no further

-rotate the mount so that the clip-on is properly lined up to the picatinny clamp

-once you are happy with the alignment, use the three nylon tipped set screws (you'll need an allen wrench for that) to lock in the position of the clip-on in the mount.  You need very little torque on the set screws.  They are there for one reason and one reason only: to keep the mount from spinning when you tighten the timing nut in the next step

-spin the timing nut onto the threaded interface of the clip-on to lock the mount in place.  You should not need the timing nut wrench, but one is in there just in case.

Here are the pieces laid out in the order in which you will need them.

When you are done, it should look like this:

Note that the mount normaly comes with two T20 screws.  I am using two thumbscrews instead, since I am popping the mount on and off all the time.  It seems to be staying put with the thumbscrews just fine.  I am hoping Annex will offer the thumbscrews as an option.

It is not quite an equivalent of a QD mount, but we needed something with an extremely low profile clamp to fit under scopes with fairly large objectives.  As is, the mount works with most scope that have objective lens diameter of 50mm or less.

I am using with with Steiner H6Xi 2-12x42 and the two work together exceedingly well.

Scoping Gas Guns
an interesting question that acme in via PM

I received this question via a private message and thought it was interesting enough to answer it in some detail.  I have been thinking a lot about appropriate optics for gas guns recently, so this came it at the right time.

 

Here is what I ahve been messing with last few days:

 

Above: 18" WOA barrel 5.56 AR-15 with Burris XTR PS 5.5-30x56 on it.

Below: 22" Satern barrel 224Valkyrie AR-15 with Delta Stryker 3.5-21x44 on it.


For obvious reasons, I am not posting who asked the question, but what I'll do is send him a link to this article, so that he gets an answer and we might have a good discussion.
Here is what I received:

Had a question for you
I have a Knights Armament SR25 6.5CM with a 14.5" barrel - I plan on shooting 100 - 600 yards at targets at 100 yd intervals
I am favoring the TT 315P with an Aimpont Acro mounted on top -( see you liked the TT315M) - would that be enough magnification?
I saw the SB SB 5-20 which offer more top end - I like the turrets on the Tanget and tooless Zero - what are your thoughts between the 2?
If I stayed 400 and under - how do you see the TT315P with the Acro Red dot against the SB 1-8 Short Dot (saw your review on that)

There isn't really enough information in the question for a simple answer, so let's consider a couple of options.

What is the gun for? 

For shooting medium range (out to 600) with occasional close range use?  If yes, go with a conventional scope and offset or piggybacked RDS.

For shooting at close distance with occasional med/long range use? If yes, so with a nice LPVO like the above mentioned S&B Short Dot 1-8x24 https://alnk.to/3J8vlFv.  It is quite capable at long range, but where it will really knock your socks off is up close and personal.

The question of what is enough magnification is pretty personal.  For me, 3-15x is plenty, but I shoot a lot off of the tripod and off of barricades which likely influences my decision.  For that, my 3-15x50 TT315M Tangent works great and 6mrad of elevation is plenty.  https://alnk.to/gVNkUXB  175gr #08 out of a shoter tube will drop in the 5 to 5.5mrad range at 600 yards.

For a dedicated long range semi-auto, other than the looks, there isn't much downside to a larger scope, which is why I set up Burris' XTR PS on the 5.56 AR pictured above.  It is for my son to learn to shoot at distance and to us in next year's BOTC match.  https://alnk.to/gp33YuR

If I were setting up an accurate semi-auto and wanted a high mag scope for it, I would likely lean toward March 4.5-28x52. https://alnk.to/dLjHgjh  It is compact, relatively light and very good optically for any use other than the dead of the night (for which we should be using clip-ons anyway).

S&B Short Dot is a very nice scope, but March is a newer design and, other than the lowest light, has an edge in terms of image fidelity and stray light control.

TT315P Tangent is a veyr ncie scope and toolles turrets are appealing.  However, there is a weight penalty to that.  For me, that was not worth it.  I ahve 5-25x56 and 7-35x Tangents and those toolless turrets are spectacular.  However, in a 3-15x50, I am quit ecomfortable with simpler 6mrad per turn knobs on the TT315M.

A morning with a chronograph

When I tell people that I am using Hornady's factory ammo for matches, I get occasionally surprised looks.  Occasionally.  Most of the time, I get fairly condescending looks from handloaders who would not let a factory round pollute the chambers of their precision rifles if their lives depended on it.

To be fair, if I had the time, I might be reloading as well.  I might be able to do better than modern factory ammo, but the truth is that I am not a quarter MOA shooter, so a lot of that would be lost on me.  The UKD matches I fidn most interesting can be done by a competent shooter with a 1MOA gun.  I am working on that first part.  I reload when I have to, but if I can get factory ammo that's not outrageously expensive and that shoots well, I will go with that every time.

I looked around and realized that I have about 600 rounds of Hornady 147gr 6.5CM factory ammo from two lots.  400 rounds from one that I will use during the match later this month.  The remainder I will likely use up practicing prior to that.

I woke up early and snuck out to the range while my family was still asleep earlier today.

I set up in the 100 yard tunnel we have.  I took my four shots to zero with the lot I plan to use for the match.  Then I fired a six shot ~0.7MOA group.  That's accurate enough for my purposes.

Here are the chronograph results:

It is slow, but accurate and consistent.

Then I shot a five round group of Hornady 147gr ammo from the other lot.

Both of those lots are not too shabby for factory ammo.  POI was within 0.2mrad between the two lots, all laterally.  

 

I had some other ammo on hand, so I fired two five shot groups with Berger 144gr hybrid target ammo and Sako TRG 136gr.

Here is what I got for five rounds of Berger:

That's not a ton of statistics, but it is a data point.  The group was ~1.1MOA

 

Here the data for the Sako TRG 136gr ammo:

This ammo showed some mild pressure signs, but not too significant.  

Again, this is not a ton of data, but Hornady is looking pretty decent here.

I'll repeat the zero retention and consistency tests a couple more times between now and June 18th when we head to Wyoming.

I might pick up a couple more boxes of Hornady 147gr from a different lot to get some more data.

More to come.
