And here's why Gemtech suggests that you only shoot these on rifles that do NOT use crush washers.

I got one of these within months of Gemtech releasing them well over a decade ago and never had a problem until last year.

Oh well. $250 lighter and 3 months later it's back in my hands, re-cerakoted and looks new again. Damn those crush washers.

I think its Geissle that makes precision rods that are caliber specific to check supressor alignment, but yea the crush washer is no bueno. At least they could fix it. I am always worried about YHM QD suppressor and swapping them back and forth.

This is enlightening for me. I run the AWC PSR on an AR. These use a proprietary "flash hider" that the can screws onto. I was told to use shims to get the "flash hider" ports aligned. Has worked fine. I need to make note of the crush washer concern as another can, for a pistol, needs to be purchased. Thanks for sharing this cautionary tale. Glad they got it back together once again.

Shims are fine as long as they are actual shims. A crush washer is a no no.

Yep, Yankee Hill specifically states crush washers are BAD, BAD, BAD. Hindsight is...
Hopefully this will inform others.

You will get the same strike from a 71/2 barrel with peel washer on.
Experience speaking.

I got some YHM shims I don’t need if anyone wants them. 5/8 ID

I have 2 SRT's in 22 and 9 along with a Bowers CAC9 Gen 1. Only the 9s have had strikes.
The 22 is 3 point welded to a 10 inch barrel as was the SRT 9mm at one time.

Doug at SRT told me from the first purchase to not use crush washers and that worked until the threads started to loose their new grip. The SRT 9 darn near spun off of my Beretta 92 with the right twist after a heavy session. Called Doug and he suggested using teflon plumbers tape if I wanted to be able to take it off easy. Been using that ever since without any issues. Dont know if there is a high heat tape available.

Wish left hand threads was the standard instead of right hand from the beginning.
HK and SIG knew better. I see it is an option from some vendors.

Shim and Rocksett all muzzle devices, especially if it’s a suppressor host. They won’t come off until you want them off.

sooo... a few years ago, my third can -
for whatever reason, I tried to save a couple $$ and bought a cheap 5.56 can ($250 I think + stamp). It was mfg'd by a local SOT who's no longer around.

I had some family visiting from Chicago and let them have some fun. She ran a couple magazines fairly quick, and what turned out to be steel (freeze plug looking) baffles got soft.

If you haven't seen one, here's what a baffle strike looks like on a 10.5
You get what cha pay for!

That pic is worth $500...LOL

Were you running video, or just lucky to catch it?

Nice pic for sure, but I'd rather have the 5 hundy! Ha!

It was captured on video
