Replacing Flash Suppressor - Tightness

[Conaso]

Awaiting stamp for 22LR sound suppressor/silencer. When replacing the flash suppressor, how tight, e.g. hand-tightened, xx lbs. torque?

I swap muzzle devices around all the time on my .22s. I just hand tighten them. With the sound suppressor I'm in the habit of checking the tightness after every mag. If it turns just a tad the POI impact shifts, and of course I don't want a loose can causing a baffle strike. As far as the flash supressor that really doesn't matter unless it got so loose it fell off... . If you had a compensator or brake that required timing that would be another matter.

You mean timing for POI? I hope not. I've have a already paid for Silencero 22Sparrow waiting for me. I bought it for my SIG P226E2 with 22LR Conv. Kit. So, with the spacer, I hope it shoot true.

You'll be fine. While hanging a sound suppressor off the muzzle can change POI, it's repeatable. My rifles and pistols all shoot great with my YHM Wraith. Yours will too. What I was talking about before is POI shifting when the can started to turn loose while firing. That happened once to me while shooting my old Ruger 22/45. Was popping away at 50 yards at junk on the backstop when all of a sudden the bullets were hitting the dirt a half foot high and left. The can had turned about a 1/4 turn loose. Gave it a quick snug back up and POI came right back. After that I check it after each mag. The suppressor has never budged on my rifles, only on the pistols.

Just use a new crush washer whenever you put a muzzle brake or flash hider back on and you won't have any problems.
Most suppressor MFG's do not want you to use a crush washer. Follow their instructions to the letter.

I guess I better get some crush washers also. Silencero recommends using a spacer, which I bought, when replacing a flash hider because the muzzle will sit too far into the suppressor. AR15 Spacers are required when using an AR15 barrel and a 22LR silencer. The normal length of threads on an AR15 barrel is .635 inches. This places the crown of the barrel too close to the first (blast) baffle in the silencer which accelerates wear on the baffle and can potentially destroy the crown.

Seems a bit ofa pain with the crush washer. Seems better to leave the can on or, if used infrequently, forget about using it.

Yeah, I don't know why they don't just build the cans to fit the standard length of threads and use a crush washer.
