ATHLON Midas CF Tripods

This year’s SHOT show was a first in many ways: first since COVID started, first time several of companies I intend to visit were not there and first time I managed to convince my brother to come along with me. Some years ago I managed to get him involved with this shooting hobby of mine, so it seemed like SHOT show would be of interest to him. Naturally, I had a more selfish purpose in mind: he is a better photographer than I am and I wanted better pictures. Perhaps, because we were both there, we ended up spending a lot of time looking at different tripods, including the new line of carbon fiber designs from Athlon. Two of those tripods showed up on my doorstep as I was heading to the airport for a work trip. It seemed only natural to turn them over to my brother for the initial look since I wasn’t around anyway. He tends to look at tripods primarily from a photography oriented standpoint, so I figured that’s a good start. I spend more time shooting guns off of tripods than cameras, so I will be adding that angle later on. I am better familiar with the various tripods out there used for precision shooting and based on the somewhat cursory look I have taken so far, Athlon is offering one hell of a value. The tripod looks to be made by the same OEM (at least on the surface of it) that makes Leofoto and Vortex Radian tripods. However, given everything Athlon bundles with theirs, they are undercutting the competition by $300-$500 depending on where you look. I'll dish out some abuse and see how they hold up, but as far as value goes, I am really impressed with what I have seen with these so far.
After this initial look, my brother held onto the CF29, while I took the CF40. We'll spend some time abusing them and if nothing breaks, we'll switch the tripods around and see if our impressions match up.

Everything further down is written by my brother. He is a member here, so if you have any specific questions, tag @Inekk

Athlon Midas carbon fiber tripods introduced this year come in four different sizes of leg diameters from 29mm to 40mm. We decided to look at the smallest ( Athlon Midas CF29 https://bit.ly/39LLDNr ) and the largest of the four ( Athlon Midas CF40 https://bit.ly/3KWxM3u ). Both models look similar enough from 100 yards away, and only when you put them side-by-side the beefiness larger model is evident. CF29 maximum height is 65” and CF40 maximum height is 71”. The other differing components besides the size of the legs are the plate, and the ball head. The larger model has 100mm base, and the smaller has 75mm base. The larger model has straight leveling base tensioner handle, while the smaller one has a triangular tensioning nob.

Both tripods came with:
a COMPLETE set of every imaginable soft gear
TWO options for the base: simple flat base with a hook on the bottom and bowl leveling base with tensioner handle. Quick web search demonstrates that adding bowl leveler easily adds about $200 to the price of the tripod, and Athlon includes them as standard equipment.
A very functional carrying bag with two handles and a permanently attached adjustable shoulder strap.
A detachable shoulder strap that can be attached to the tripod itself.
Leg spikes with three allen wrenches are in the side pocket along with the manual. These can replace the rubber feet if you are taking your tripod into the rough terrain.
Removable cloth wraps with molle system on two of the legs. At first it’s confusing, until you locate a shoulder pad that can be attached to those specifically to move your entire set up without even having to close the legs!
The last but not the least soft accessory is a Velcro-attached tripod hammock.

None of these are typically included in a standard package of tripods of comparable size. Finding everything included in one reasonable price, makes it a bargain for any photographer/shooter who needs a steady set of legs for long telephoto work.

If one is looking for a tripod for photography work only, the 29mm version would be more than adequate. Athlon rates CF 29 model for up to 33lbs and CF40 model up to 88lbs. Naturally, it comes with added weight. CF29 weighs only 5.5lbs, while CF40 weighs nearly 3lbs more (8.4lbs). My prediction is that CF29 can support more. I currently weigh 220lbs, and CF40 didn’t even flinch when I hang from it while legs are completely extended.

Both tripods come with an Athlon branded ball heads. Both are massive and have three knobs: one massive knob on one side and two smaller knobs on the other side. The large knob is to adjust/lock the movement of the ball. The smaller on the bottom is to lock/unlock the fluid panning of the ball head. The smaller know slightly above is called “Friction Control”. I only needed to adjust the friction control when I had the largest lens with gimbal adapter (Induro GHBA). This accessory allows using the usual ball head with very large telephoto lenses and locking the ball head down is paramount to avoid a catastrophe. Both ball heads (from CF29 and CF40) have no problems with this task.

The bowl tensioners are not exactly the same on these two models. CF 29 has triangular knob, as you can see in the picture below. CF40 has a longer straight handle instead of a knob. These are all the hardware accessories: the ball head, the Arca-Swiss plate, the bowl with bowl tensioner, and a flat plate with a hook. You can save a bit of weight and use a flat plate with a hook, or opt for a greater adjustability and use the bowl with the tensioner. CF29 comes with 75mm bowl. CF 40 comes with 100mm bowl.
The legs have standard three angles. The black spacer that allows you to change the angles has Athlon logo on it. This worked fine, but this assembly seemed like the “flimsiest” part of the tripod.

There are two bubble levels: one in the base of the legs and one in the clamp of the ball head. Surprisingly the one that came with the CF29 ball head fell out when we were taking it out from the package for the very first time! We were able to find it and a drop of general-purpose glue solved the issue. We looked on the bottom, and there was some glue there, but it clearly failed at the manufacturing. No problems popped up since we fixed it.

Here you can see the angle that you can adjust the bowl by itself. I found it useful in the field. The least precise way to adjust the level of the base of the legs is to manipulate the length of the legs. One can’t help it if you on a slope, but I always to try to minimize these adjustments. The legs lock with a common twist lock, not a clamp. You can’t really “see” if you forgot to lock one segment or not. I personally prefer the clamps for that reason, but these are not an option in Athlon line up. To be fair, many people prefer the twist locks because of lower profile, and less chance of catching on things, be that closing, straps or vegetation.

Changing from flat base to bowl with tensioner is very easy. Just relax the clamp, push the safety button (blue arrow) and pull out. I found that if the clamp is not tightened after the replacement, the safety button will still prevent the bowl or the flat plate from falling out, but it would not be held firmly enough for long exposure photography.

This is the lowest angle to bring the base down to the ground. CF29’s lowest height is 9”. CF40’s lowest height is 10”

There is a little height difference between CF29 and CF40
The height of the tripod is evident here. The person holding it here is 6’1” tall. Unless you are over 6’4” there is very little chance that you would ever need to extend the legs of either tripod fully.

The shoulder pad installed allows one to move the whole set up from place to place without changing any angles, legs, etc.

Interestingly the quality of the accessories was not the same between two tripods. Some of the stitching of the shoulder pad in Midas CF40 model is suboptimal. Midas CF29 came completely fine, with no hanging threads, and perfectly straight suturing lines.

Preliminary Conclusion:

If I google “what is the heaviest photography lens?”, there are some incredible monsters out there such as Sigma-300-800mm-Ultra-Telephoto-Cameras at 11lbs for $8K. CF29 would handle it easily with even the largest DSLR attached.
On the other hand Canon 1200mm f/5.6 weighs 36 lbs. would be too heavy for CF29, and it would only set you back about $80,000.
And finally, Sigma 200-500mm f/2.8, that exceeds CF29 weight limit at 35 lbs. This green monster would set you back about $30,000. I have never seen this lens in real life, but I guess if you can justify spending that kind of money for your photography the extra $300 and extra 3lbs of weight of CF40 would not be a problem for you!

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.

Had to switch to a different streaming service

Rumble Studio crapped out on me. so I hadd to stream using a different service

Well, imagine THAT....

I wonder if all of the Youtube frauds who spent the last few weeks shamelessly lying for clicks are going to go apologize to Sig now.

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.
