I'm sure this has been beaten to death, but I can't find a specific thread, so here's mine.

I need to change the gas block on my 6721 (16" HBAR, A3 if that matters)). Last time I got a chance to work on it, I started messing with it and I noticed there's a little pin. I've read different things...some say this is just a pin and threads, others say this is pinned and welded and I'm gonna have to drimmel tool it off.

I barely trust myself to cut pie ot turkey, let alone hack through a flash suppressor.

If its not welded,  can I just use an Allen wrench of the right size and work the pin out and unscrew it from the barrel as normal?  If so, will I need a new pin and flash hider?

I would get a shop to do it, but no one anywhere near me has the time or is willing to do it.

thanks you!!!

I wonder why anyone would pin a flash suppressor on a 16 inch barrel?  If it is pinned, there is no need to pin it when you replace it, because it is already legal length.  If you mean the pins holding the gas block on, just drive them out left to right with a good punch and hammer.

seriously---if you say yourself that you shouldn't cut a turkey, gunsmithing isn't for you. don't fuck with it----call ADCO and send it to them. or post in your HTF to see if there's any recommended smiths in your area that can help you. there may even be someone close by that is willing to help you out.

Okay, I'm stupid.  I hadn't looked at ot for awhiole and was going to work on it this weekend. You are correct. I was thinking of the pin in the gas block. Don't know why my brain criss-crossed those wires.

Got a good punch and hammer. Should be good for it.

I do okay. I'm just not used to cutting metal and don't trust myself without some more practice. Help is few and far between so I have to rely on myself to do this stuff. Best way to learn is to do it.


Thanks for the input folks. Apologies for wasting your time on a stupid question.

This is true.  If you don't have someone around to help you, youtube is actually very helpful.

Honestly, a few years ago I didn't know jack shit about putting an AR15 together.  Between youtube and common sense I figured it out and now I have built and/or helped build 20+ AR15, AR10, even a 1911.  Once you start getting into it, you realize how simple it all really is.

Yes! Youtube pulled me through my build when I got stuck on some things. I now have a pretty sweet FrankeM4. Now I'm just tooling with the options.
I learn more from doing than watching, so having a visual reference going as I do something helps immensely.

I'm gonna tackle a 1911 sometime. I have another AR to build first though. lol

thanks!~

GoldZulu---sorry if I sounded harsh with my post. you are correct that the best way to learn is by doing it. I was just kinda thrown by the comments you made in your original post.

you really should try to find someone on your HTF that can help for the first time, or watch a bunch of videos.
