Crush washer larger than the comp and barrel

[BenL]

I'm setting up my 308 AR to shoot Heavy Metal division this year. For the comp, I picked up a SJC Titan Comp because it received good reviews. the base of the comp is the same diameter as the barrel: .750". However, the crush washer they included is larger and sticks out a little. Other than looks (don't really care about that), should this be OK? It seemed really easy to turn (~18-20 ft/lbs.) I test fired it and it didn't shoot loose (only 30 rounds, though.) I didn't want to use Rockset because I may want to switch it back to an AAC suppressor adapter.

You can see it in this picture:

Did you try shims?

Get rid of the crush washer and get some shims from AAC. Washers are nothing but trouble.

Rocksett that bitch and be done with it.

If you have to remove it later, set the muzzle in boiling hot water for an hour - it pops right off after soaking in hot water.

Been there, done that.

No, but I do have some left over from AAC.

I was hoping a crush washer would work (easier removal later.)

Yeah, so have I. My experiences ranged from, "Oh, that wasn't so bad", to "Holy Crap!! Is that welded on??"

You guys aren't supportive to my bad idea at all.

Fine, shims and Rocksett it is.

I've learned that if you don't go super anal about degreasing everything, the Rocksett still holds beautifully but isn't impossible to remove when needed.

That's probably my problem. I go: wire brush, ethanol, electric contact cleaner, then Rocksett. Works great, but you're F'd if you ever want to get it off.

Why not go with an AAC brake? I have one on my 3-Gun AR, it works great and it is threaded for an AAC silencer. I got the same brake for my house AR so they can use the same can, if I ever get around to getting one.

Or Thunderbeast brake for CB or Ultra series cans

Not nearly as efficient. With the SJC brake, it recoils like a .223 (loud enough to make your ears bleed, but really stays on target.)

That's what we are here for.

OK dumb question. When installing a crush washer does the taper side go towards the barrel or flash suppressor/brake?

Tapered side against the barrel.

If it's not being used to host a suppressor, a crush washer will be fine.
