Overtorquing flash hider

[Hmac]

You can't overtorque a crush washer. The torque stays the same as it crushes, until it completely crushes. The whole idea is to just turn it until it's indexed. Very simple device, pretty much a no-brainer. You didn't damage anything except the crush washer, which is, what....$.75. I've never used anything except crush washers for years to install a muzzle device. Shims are a PITA. Maybe a preferable route for a precision build but I wouldn't know...I've never striven for precision exactly.

Op-Which barrel did you buy? The stainless one?

Yessir, I have the SPR stainless. Centerpiece of my Centurion build.
It’s not like the recoil on any 16” (or even my 12.5”) is actually bad, but I liked BRT’s gas design and profile. And, the barrel is undoubtedly more accurate than I am capable, so I also like the idea of a known good quality.
Kind of like learning on a Martin over a Yamaha; you don’t need to, but why not?

I'd bet that there are some garbage crush washers out there that don't meet this description. For A2 flash hiders, I use them too. I even re-use them when they've not been smooshed much.

I've installed so many shim devices that I dread that ass ache incredibly.

There is no torques value for an A2 styled flash hider. The manual clearly states it is based upon alignment.
