Unless it was silver soldered I would thing once you grinded the weld off the pin would fall and it you could easily back the break off no?  I got one I'm gonna do also but have been hesitant

I've cut the brake in half length wise down both sides then split it with a cold chisel . That works most of the time to remove.

I shaved the weld down to the pin on mine, turned it upside down and rapped on it, pin dropped out. MD spun right off.

What'd they hit you for that?

20 bucks. It was worth it to me.

It was to make room for the AAC quick connect flash hider for a future suppressor.

I did this on an HK91 clone once and it worked well.  I couldn't grind down the weld over the pin because it had been done so well I couldn't tell where the pin was.

Hell, for $20 it's almost not worth doing it yourself.

Maybe a stupid question, but why was that barrel pinned?

yes i thought i'd be able to shave of the weld but the pin wouldn't budge, i think the pin was small and really inside there. As i dremed lower i couldn't see where the pin started.  It was welded on there so good i pretty much had to dremel down to the thread. I was thinking about shipping it off to adco couple years ago but never did.

I was thinking the same thing......that looks like a 16" barrel to me.

this was my first AR i bought at a local shop, turns out they did sales in california as well . In cali a muzzle break has to be pinned, mag release disabled, with a fixed stock i didn't know better and they sold me a CA compliant AR (bastards) Didn't know that until a year later. The muzzle was the last thing i needed to get it back to stock configuration

Still have that bullet button?  Putting together a parts kit for a Bernie supporter.  Gave him a functional blem 80% - his LRBHO will be intermittent.  Gonna give him some 10 round mags, maybe a Thorsden stock.

That's truly a bummer, but they gave you bad information.
Muzzle devices only need to be pinned/welded to conform with the 16" federal requirement, same as everyone else. The disabled mag release and fixed stock part is also wrong, to be brief, we have three common statuses/configurations for "assault weapons;"
1. "Fixed magazine rifles" that can have "features" like flash hiders, collapsible stocks, and pistol grips, but your magazine/magazine release is fixed in some manner.
2. "Featureless" which of course means you don't have features, so instead you have muzzle brakes, fixed stocks, and grip wraps or some other grip replacement, otherwise it's a normal rifle with a regular mag release.
3. "Registered Assault Weapons" which are, you got it, registered with the state and are otherwise just like free state weapons. Except now your gun is classed differently and has extra restrictions, like transportation and destination requirements, can't be transferred to another person, etc.

I don't meant to derail the thread, just a small clarification (and for CA laws this is incredibly brief.)

Hi OP, or anyone who can answer, what dremel wheel did you use? I'm going to do this to a couple of pin/welded A2 flash hiders soon. Planning on trying the grind down the weld method first. If no luck then the cut both sides and pry apart method.

I used the wheel that it came with. ive seen others used a reinforced wheel , mine was a standard wheel that wasn't to thin

I have run into a few barrels that were pinned so well that you could not find the weld on the pin, what I have done with those is, I take a dremel with a small sanding drum on them and just keep going around the the MD until you break through the coating and then you will see the pin/weld and then you can drill it if you have a punch, drill press or small mill.  That way if you are so inclined, you can reuse the MD, just need to cold blue it and it works fine.  I normally do it on my mill with a small diameter mill so you can follow the pin down until you break through the weld section, then the pin will fall out.
