Hello,
I just picked up my new Saker 762 today. My host has an 11.5" BCM light weight barrel. http://www.bravocompanyusa.com/BCM-Standard-11-5-Carbine-Barrel-light-weight-p/bcm-brl-s-11lw%20std.htm
I didn’t think about it when I bought the barrel, but the shoulder area must be .625" OD like the gas block journal. Does anybody make a shim kit or peel washer than is .625" OD? The .75" OD don’t seem appropriate.
Look at this system. http://precisionarmament.com/product/accu-washer-system/ The ground washers are 3/4" OD but much thicker than typical shims.
Those look nice. Thanks for the suggestion.
The only downside is the cost if you are only doing one barrel. I can scan and send you the instructions if it helps with your decision.
Don’t go through the trouble to scan, but thanks for the offer. I will most likely go with these unless I find a better solution. I don’t mind paying $25 for shims when you consider the cost of the suppressor and host.
I used the Precision Armament set, fan-****ing-tastic stuff
These are all I use now, regardless of muzzle device.
I’m so glad that the days of Peel Washers are behind us. I’ll have to check out a set of the precisionarmament.com washers.
Oh gawd! How many minutes of my life have I already donated to peel washers? I’m never going back.
AAC has some shims as well, but I haven’t used them.
Even better, I’m glad the days of the crush washer are over
Pappabear runs a lot of their mounts, so I’ve ended up with a bunch of their shim kits from installing his. They’re pretty good.
Sounds like the Accu-Washers are the bee’s knees. I just placed my order.
They’re awesome. I’m still using ones from the first set I bought and I’ve done 5 rifles so far. They are just the right firmness but soft enough to allow around 3 consecutively sized washers to be considered usable for one muzzle device so if the ideal size you need for a specific mount has already been used you can find one that’s close enough to work most of the time.
Plus the set lets you fine tune your installation for timed devices. A smaller sized washer with minimal torque required to time a suppressor mount used with Rocksett or a slightly larger washer to be able to crank down on for whatever reason. Well worth the price IYAM.
The washers are NOT the least bit soft!!! You will wring off the threads on your barrel before compressing them! Using your logic one would just smear some rockset on it and hand tighten to time the MD. Read the instructions.
So their different thickness then?
Yes, but they are all relatively very thick compared to other shim sets.
For the record the thinnest one is twice as thick as the largest AAC shim. Preaching to the choir to you but think of it a system not shims.
Roger that and thank you for the info.
What are you talking about? You read “just the right firmness but soft enough…” as “they’re soft”? Cause that’s not how that works.
Regardless, these washers do compress. We’re not talking crush washer here but there is enough softness [dont read: soft] to allow for varying degrees of torque. Try putting one on, torquing your MD down, and then removing it. You’ll notice that it’s been compressed and that it is no longer the same thickness as before and you didn’t even have to wring off your barrel threads. That’s why the instructions you suggest I read advise that the MD will rotate an additional 10-30 degrees after reaching hand tightened.
But yet using “my logic” the answer is to smear rocksett on there and hand tighten to time the MD? I’m not even sure how you got to that conclusion or what the point of your comment was honestly.
I dont really want to get in the middle of this spat, but I would like to add a couple comments about the terms “soft” and “compressible”. What we are really talking about is deformation. Do the washers deform when the muzzle device is tightened down? Absolutely. Elastic materials will deform under stress. They can either deform elastically or plastically.
I think the question we should be asking is what type of deformation is occuring. Elastic deformation is when you stress a material, it deforms, and comes back to its original shap when unloaded. A spring working in its intended range is a good example of this. Now take that spring and streatch it out beyond where it is intended. It will be permanantly deformed because you have exceeded the elastic limit and have plastically deformed the material. A crush washer is another good example of plastic deformation.
Edit to add: It seems to me that these washers are intended to work in the elastic range of the material, but I do not have experience with them yet.
