Shimming a Muzzle Device

[titsonritz]

Have you looked into Accu-Washers?

I use them almost exclusively, regardless of if I'm doing a pin & weld.

Same here.

What is the consensus on indexing a pinned flash hider? Do most of you guys do it?

I also index on p/w jobs.

Whether you decide to index it or not, make sure the gunsmith your using is aware that it is a suppressor mount, and cannot use a crush washer. I had one sub in a crush washer on a P/W device once, and I’m still a little annoyed years later.

These are absolute trash. Avoid.

I had four installed per the directions and they all came loose shooting suppressed

On a pin and weld I would index. And I also recommend the Precision Armament AccuWashers. They are by far the best I've used.

Did the same person install all four?

Respectfully, wouldn't you be able to choose thicker shims as needed to get the desired torque and combine that with Rocksett? Just curious.

Well I installed all 4 myself; cleaned, degreased, and used Rocksett. Timed all of them and torqued to 40ft lbs.

Very interesting. I'll have to stick with the SF shims for my suppressed options. I'd hate to risk a baffle strike.

OP..... did you open the flash hider package up? Every Dead Air flash hider and brake I have purchased came with a shim kit. It is sandwiched between the black card stock in the package.

And it's because of the shim they shot loose?
