March introduces a new FFP 1.5-15x42 Scope

March has finally released the specs on their new 1.5-15x42 scope that can be configured as FFP or DFP (Dual Focal Plane) design.
They just told me that they decided to pull out of SHOT Show in January, so unfortunately I will not be able to get my hands on this scope for a bit. They will send me one of the first production units for a full test. I expect that to happen some time in the spring, around March/April.
The price for the DFP version of the scope is set to $3150 https://marchscopes.com/scopes/d15v42iml-2/
and FFP is $3050 https://marchscopes.com/scopes/d15v42iml-3/.

The DFP reticle is somewhat reminiscent of the design in the 1-10x24 Shorty.

The FFP is a simpler pattern with a dot-donut primary, ostensibly for speed. I am somewhat mixed on how well that would work in a scope like this, so I am planning to focus on the DFP version. On paper at least, it looks like a more appropriate reticle for this scope.

It is going to be short at around 10.5" and weigh in around 24 ounces. This scope has every chance of becoming one of the better general purpose/crossover designs on the market.

This scope is built with the regular FOV eyepiece, rather than the wide angle one that comes with 5-42x and 4.5-28x. Apparent FOV of this scope is right around 20 degrees, which should work well enough given the application.

The exit pupil is listed at 8.7mm on 1.5x, so we can reasonably assume that it should be pretty good in low light. I do not know what the exit pupil is on intermediate magnifications, but I'll measure it when it gets here.

One of the reasons I am so interested in this scope is that it should work really well as a standalone hunting scope and when coupled with a clip-on.

For example, on paper, it looks like a near perfect scope for my 8.6 Blackout Fix that I use for four things:

  • regular hunting with supersonic ammo out to 400-500 yards or so.
    42mm objective together with March excellent image quality should be good for this.
  • night hunting for pigs using subsonic ammo and thermal clip-on. With 1.5x on the low end (70ft @ 100yds FOV) it should match well with damn near every clip-on on the market
    -long range shooting with subsonic target loads. With side-focus, 15x on the high end and 40mrad of adjustment range, it should be perfect. I get about 30-35mrad of drop at 800 yards.
    -indoor dry practice. It focuses down to 10 yards.

It really sounds like a very promising design. I'll need to see how the eyebox and depth of field are, of course, but I am cautiously optimistic.

March has 3-24x42 and 3-24x42 scopes in the same approximate weight range.

I used to own the 3-24x42 and currently have the 3-24x52. I know that in some parts of the world, the 42mm model outsells the 52mm one, but I definitely prefer the latter design.

To me, in terms of functionality, the 1.5-15x42 is a better fit than the 3-24x42 and a nice complement to the 3-24x52.

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.
