I just got my rifle back from the gunsmith today, he put a A2 F/S on my post ban barrel.

My question is when I ask him if he put on a crushed or peeled washer on he said that he put on some kind of nut. (He called it a name and said it was better than those washers) Is this the proper ? It looks like there is a nut then the F/S.

Dont get me wrong... its look great, I just dont know what the difference?

can you post a pic? I don't ever recall any "nuts" put on a muzzle except on AKs.

It is a probably washer, just not a typical peel washer. Not a big deal, there are plenty of people using crush washers, they work well.

if it looks like a nut than what he probably did was put on a lock nut. similar to the mucilek(cant spell it).

he probably did this cause it would be easier to time it with a lock nut, not the best way cause it could eventually work itself loose.

if it has flats than it would be a lock nut but if it is rounded like the barrel then its some sort of washer

A lock washer maybe? Is the washer split? or is it contiguous all the way around the barrel?

A pic would do wonders.

Man, that dont look right. Take it back and have him do it right. That looks like "homesmithing" to me.

Looks like it's a thin lock nut. Not a standard way to attach the hider but it should work just fine. Lock nuts are used in a lot of applications where vibration can cause things to loosen up.

I see he went to the WECSOG institute, it will work, but is not the way it is supposed to be.

he needed to use the proper crush washer or a peel washer

Mechanically speaking, a locking nut is more secure than a washer.

Looks great and nothing wrong using that washer.

Wile E. Coyote School Of Gunsmithing. (Or something like that)

It looks like an AR180 set-up with that nut on the end. (Read, effective, but cheap)

It doesn't look bad, but it does not look correct.

jam nut
Link Posted: 10/12/2004 2:25:04 PM EST
That is not correct.

Crush/Peel washers are used for a reason.

The Jam Nut your "gunsmith" used will work loose as the barrel goes through heating/cooling cycles due to different expansion rates of nut and Flash Hider.

The Jam Nut your "gunsmith" used may also reduce the effectiveness of your Flash Hider by placing the restrictor in the base of the FH too far from the muzzle (thus creating a mini expansion chamber before gases get to the FH).

In any event, this is not the accepted method to mount a FH. Will it work for you? Maybe. Would I accept this buthcher job? Absolutely not.

Ok, now what?

Can I, myself just get a crushed/peeled washer and replace the jam nut or do I need to have a "pro" do it?

Please dont tell me may barrel isn't wrecked.....

Thanks
Bri

Whats better, Crushed or peeled washer?

Take it off yourself, and replace it with a crush washer as it will be easier to time your FS. It is a simple deal.

There's no way a jam nut should have damaged your barrel. I can think of several possible reasons why your smith may have used it, none of which are acceptable.

1. He didn't have the correct peel washer or crush washer.
2. A jam nut would make it real easy to index an A2 flash suppressor.
3. A jam nut is less tedious than a peel washer.
4. A jam nut can be employed without the use of a set of AR-15 barrel vice blocks, which your smith may not own. A crush or peel washer usually cannot.

Bottom line--it's a shortcut method of installing a flash suppressor. While it looks fine, at least in my book, it isn't the accepted way of doing the job. Will it shoot loose? I dunno, but it seems like all the AR smiths and the military would be installing them that way if it was. Just my .02.

It's a pretty easy job to do yourself. But just be careful about marring the finish of the barrel/flash hider when you clamp it down and index the F.S. Ideally your gunsmith should make it right, but if he is of the mindset that a locknut is better than a crush washer, then you might be better off doing it yourself.
