Just have one quick question for anyone who has used one of these. After looking at their website, it states that the brake was designed for use with a Gemtech suppressor, therefore, it comes with a peel washer.

Now my question is, if I am not going to run a suppressor on my XCR, do I still need to use a peel washer or can I just use a crush washer? It seems to me that it would be easier to install with a crush washer due to the peel washer having to be heated to remove the layers (at least this is what the instructions call for).

Any help would be appreciated.

If I remember correctly the peal washer , by pealing, allows you adjust the thickness of the washer and so you can position the muzzle break ports in the correct orientation. The crush washer limits length of adjustment. As a aside note IMHO compensators are not necessary for these small calibers and are really loud to anyone next to you. I had a H&H .375 once and it kicked so bad I got rid of it and went back to my .338 for dangerous game. I had 2 narrow slits cut in the barrel of my 338,about a inch or so back from the muzzle and the that helped with the recoil but did annoy any one standing behind me. I just use the standard bird cage flash hider on my AR/XCR type rifles.

I believe you are correct. By peeling a layer at a time, you can orientate the brake by placing the logo at the 12 o clock position. And essentially, this is the same with a crush washer, just tighten until it is where you want it. I just wanted to make sure it is okay to use a crush washer instead of the peel washer due to easier installation. I guess it probably wont make a difference since I am not using a suppressor.

Thanks for the reply

I wouldn't pay more for the one with ears for mounting the supressor if you don't intend on using it ever with a supressor.

As far as crush vs. peel, you don't ever want to use a cruch washer with supressors. If for some reason they don't crush "evenly" as you tighten there is a chance that they wont be perfectly concentric with the bore. While this wouldn't be a big deal with no silencer the broblem is magnified when you have 4+ inches of can on the end. This is what leads to baffle strikes. You will see that most silencer manufacturers that use a fast attach type system have a muzzle device that doesn't need to be clocked. You don't use any type of washer, just some Loktite.

If you haven't ordered yet contat Roy at Aussie Arms, I have purchased 4 PWS brakes from him and he will treat you right.

This may be a dumb question, but I was looking at the XCR spec's and they say the berrel is threaded 5/8x24 and the PWS website says the FSC556 is threaded 1/2x28. So what gives? Are these compatable or not? Or is it "just close enough"?

Thanks.

I think the XCR 5.56 is 1/2x28, I put the FSC556 on mine.

If you dig around on the FAQ page it states that the 5.56 has a 1/2-28 thread and the others are 5/8-24. I'd measure mine, but I'm still waiting for it...

First impressions on shooting this brake!!!

1.) Holy crap this thing directs pressure to the shooter!!!!
2.) Damn! any muzzle rise is gone.
3.) I'll take 2 bi-lock models please.

My initial thought after shooting my 11" 6.8SPC with this brake

"Self, wear long sleeves if you like your arm hair"

I can totally imagine! the wolf .223 ammo is bad enough for me.

I had one mounted to my M4 (work gun) and my buddies called it the Buddy F*cker Front End. It did keep the muzzle down, by man will it ring your ears in an enclosed area! Kinda felt like I was gonna get a nose bleed after continuous shooting.
