Need a gunsmith recommendation for drilling a barrel and gas block.

Drifting them in the correct direction helps substantially.

Lol! Yes that helps quite a bit.

We use an 1/8" (.125") pin, which is similar in size to a mil-spec taper pin.

1/8 X 5/8 ?

Honestly, I've never had a problem with either one using IG's technique of a barrel vise jaws, large pin punch and 1" hammer.

Got a link to that technique? I need to remove a BCM pinned FSB sometime in the next couple of weeks.

Thanks.

I mentioned the method in this thread. > https://www.ar15.com/forums/AR-15/Ne...-it-/4-770624/

If you scroll all the way down, samuse has a picture of how the barrel should be placed in the vise using barrel blocks. It's really the best method.

All you need is a vice and it will press the pins loose, which you can then punch out easily.

He describes it here, I've done it multiple times and it works like a charm. I just removed a BCM FSB a couple of weeks ago to replace the Magpul MOE handguard with a Centurion Mlok C4 FSB handguard, not a single hitch.

Remove and reinstall front sight?

Thank you both georgeib and ToR for the replies!

That's the thread I originally read when I was trying to remove my BCM FSB. It didn't work for me because I think I got one that was a bit "extra." Even after removing the pins and trying to press them back in (the same slots they came out of, and in the correct orientation), I haven't been able to get them all the way in.

You got it, man! Let us know how it works out for you.

I have used the Triarc easy pin gas block a couple of times. Super easy and then I dont need to send anything off and wait.
