What are the proper methods to permanantly attach muzzle brake

[thrasherfox]

What are accepted methods of permanently attaching a muzzle brake.

I was looking at Loctite Red. and it says the only way to remove something with that on there is you have to heat it up to 450 degrees for 5 minutes, then remove the bolt while it is still hot.

This seems as though it would even be better than pins that are factory installed. I have had experience with those and they snap pretty easy.


Anyone know if the loctite would be acceptable? if not does anyone have a list of acceptable methods?

Welded, blind pinned or 1,100 degree silver solder.

Loctite won't keep you out of jail.

Jail is only an issue if the barrel is less than 16" front bolt face to the end of the barrel.

As long as the barrel itself is 16" or longer from bolt face to the end without a muzzle brake then it should be fine right?

Or is there some other law in California in regards to muzzle brakes that I am not aware of?

Just wondering because I know someone who has a Kel-Tec they purchased in California and on the end of it there is a cap that just screws on. it has the same threads as an AR ( 1/2 -28 ) and the person wants to put a muzzle brake on it.

I don't think they make a Kel-tec that doesn't have a long arse barrel on it.

But he and I didn't know if maybe taking the cap off and putting a muzzle brake on it required a permanent mounting. And once he finds the muzzle brake he likes he doesn't plan on taking it off. So he figured it wouldn't hurt to just have it permanently attached. And if he is going to have it permanently attached he felt he might as well do it in whatever method is the accepted method so there is never any issues in the future with it.

He would prefer to do it himself instead of paying a gunsmith to do it, especially since there are not any close to where he lives.

If that is a rifle then don't worry about it, as long as the barrel is at least 16".
Locktite won't cut it, Like the lelandEOD stated pin and weld, weld (the weld must cover at least 50% of the circumfrince in at least 3 places), or silver solder that has a melting point above 1200f

So far it sounds like pinning, welding or silver solder seems to be the only acceptable methods. Thinking he is going to need to drive a long way or ship it off to somebody.

Ok, thanks!!

If the barrel is 16" there is no need to do anything. The only reason any muzzle device needs to be permenently attached is to get the barrel length up to the 16" federal min. Why pay money or risk damaging something for no reason.
BTW, the pinning, is pinning and welding.

I was making the assumption that you were looking for a permanent method to bring the OAL barrel length into title I configuration from title II.

If the barrel is over 16.1" measured as described above, there is no need to do anything.

I have never heard that the BATFE requires the weld to cover more than 50% of the circumference.

I have. One opinion letter said if using multiple beads, one of them needs to be 1/3 the circumference. With another required spot or two, might as well weld up the whole damn thing. Must be why blind pinning is much more popular.

Don't try to make sense of the ATF and their rulings. It will just make your head hurt.

Where are the letters that say that?

I always thought pinning would be best, can you pin and cover with jb weld? It says weld in the name!

[tonelar]

16" barrels don't need to have muzzle
devices permanently attached

Ryan; dja really wanna roll the dice on a federal sbr case?

Well, you just hit the nail on the head. There is no consistency in those letters because the answer is often up to the interpretation of a given agent/inspector/examiner on a given day. Their responses can vary greatly and there is almost nothing black and white.

It's basically the calling card of tyranny: "Because we can".

Awesome.

The red loctite with some JB smeared on the joint and sprayed black would pass the eyeball/wrench test...

Hypothetically of course....

and when the put your barrel in a vise and have a 2-3 foot wrench and spin the brake off= felony???

Never seen a cop car equipped with a vise and 3 foot monkey wrench....

I said eyeball/wrench test. As in a range/patrol officer...
