Not only that but the necessity for a cheek rest can be mostly done away with. I have low rings, yet a 50mm objective will fit. It is a fit that prevents a scope cap from fitting, though. I made a cutout in my cap to make it fit. I luv mine but the 1 in a million hapenstance occurred right out of the box.
An ejected rd. jammed between the mount and the rod handle, raising the front of the mount off the receiver. Has not happened since.
In order to stop the front from possibly rising ( it is not secured) I placed a piece of folded foil blister pack between the rear of the mount and receiver. It was a quick stop gap and I'll do a proper job, maybe.
I wanted to replace the skyscraper Spfld. gen 3 I have and without cheekpiece my chin was practically on the stock. With this one it's just below my cheekbone. So, a considerable improvement.
Yes, I mulled over purchase for a few years, until I recently collected a Leatherwood ART IV. I will replace my present scope with that one

 

I have one on my socom and love it. Well built and holds zero. If you don’t plan to use irons/don’t mind removing the rear sight, it is a fantastic design.

 

how do you like that stock? do you feel like its worth the investment?

 

I bought one in 2018 for my Norinco M305 build.

There is a peep hole that allows you to use the iron sights. I tested it while waiting for the scope. It shot a bit low at 50 m but it was easy enough to aim higher and hit the center

It’s a well made mount, and seems sturdy and rigid on the rifle.

Now I can’t say that I shot it extensively because I was disappointed with the rifle’s accuracy at 300 meters, but I think it lays more with the Norinco. Mind you this thread makes me want to take it to the range again and shoot it some more, maybe try different bullet weights.

That was one of the questions I had about the casm was the peep hole. Thinking about ordering one for my socom.

 

Ran one on my previous EBR and will be running one on my Scout once it arrives later this week/month...

 

I’ve got the gen 2 steel one and it has a rear sight peep. While it’s not as good as regualr irons, it’s better than not having irons at all. I prefer the CASM to the Sadlak.

 

My only issue is you don't get any comms from M14.ca when your item ships...nor a tracking #...its a bit annoying but your mount shows up about 2 weeks from order....

 

I ordered one of their BLACK ARROW; spring guide. The part that locks into the receiver was little bit to big; so I filed it down.

 

I was highly considering one of these, I just don’t know I can’t bring myself to remove the irons.

 

As I see it, if you use irons regular, the only real options are no scope/exclusively irons, or basset mount so you can go back and forth easily. I never find the scope mounts that allow you to “still use irons” as being very functional.

 

Removed it double posted.

 

I have one in my M305 and am very happy. As for the peep hole, I have bad eyes, so not really useful.

 

I have ran this mount since 2018. installed meticulously (I'm an engineer and anal about like that) and have shot about 2k-3k rounds with no issues. it gets hot as expected during higher volume training sessions but I wanted to test it. no change/loss in zero. I have the aluminum version (opted for weight savings). I changed out the front sight so I can run a muzzle break (recoils like an ar15. very controllable with rapid fire) of my choice so the peep sight is useless to me unfortunately. front sight is a NM blade when I used to run this rifle iron sights only. through my extensive experience and rough handling, I trust it with my life. If I did things all over, I would go with the steel version, use high temp epoxy and "bed" the front platform to the top of the rifle. its not permanent and it'll keep things more rigid and minimize/eliminate movement concerns. or tack weld 4 corners.

although I dont expect the mount to see 400*F of heat where I would be concerned with warping, I did see temps reach mid 300s after about 200 rounds of rapid fire. I dont think it'll ever got hotter than that even with more rounds but a hard "bump" from a fall or something would give me concerns enough to check my zero again before trusting it with my life.

product: CASM mount aluminum. Modified 2 picatinny rails (still functional) with dremel for clearance of zoom ring. Optic is mounted as low as physically possible.
rifle: Springfield Armory Socom 16 (accuracy: 3/4" @ 100 using Barnes TTSX (my hunting & home defense round))
optic: Primary Arms 1-6 gen 3

please let me now if anyone has any questions.

 

I've been considering trying one of these scope mounts for some time, and I'm interested in first-hand experience with them. It seems like a sound concept. Has anyone used one extensively - either aluminum or steel?

You wouldn't have to worry about the single side mounting screw staying tight, and it would definitely center the scope over the bore.

I have had one since they were first released and love it----I have had it on and off a few times and still keep coming back to it, great fit, holds zero, easy install--as other have said, the only downfall I can think of is the need to remove the rear sight.

 

What break are you using & what grain TTXS are you shootings?

 

I ordered my CASM about 4 weeks ago, and haven’t recieved information on shipping or a response from the website email. How long did it take to receive your mount?

 

I got mine about 20 months ago. It probably took a month or so. Shipping from Canada seems OK but slow. The tariff nonsense probably isn’t helping either. I don’t think you have anything to worry about but usps once it’s in their hands. 🙄 CAsm are great people to deal with, btw. Did you try calling them? I ordered over the phone.

 

I couldn’t find a phone number on the website. I’ll check it again thank you.

 

At one point had it on my Socom and it held up fine

 

I’ve used the steel CASM mount for several years on my M1A, and it’s been rock-solid. The design eliminates canting issues common with some other mounts, and the single screw has never loosened under recoil - though I still check it periodically. The steel version adds weight but feels indestructible; if you’re concerned about bulk, the aluminum model might suffice for lighter use. Zero retention has been excellent, even after dismounting and remounting.

 

Mine’s aluminum. The last few times I’ve checked their site, only the aluminum was available.
