[ARCHIVED THREAD] - Question on Gas Block for Dimpled Barrel

Posted: 8/29/2014 3:38:22 PM EDT

I'm going to pick up a 14.5" Midlength, Enhanced LW barrel from BCM. The BCM website says the barrel comes dimpled for a gas block.

Would you recommend using the dimples and installing a set screw gas block? Or ignoring them and installing a clamp on?

I have had equal success. I know a lot of people have particular opinions but I say find the block you want and go with. A pinned block ,is however, a significant upgrade.

I use the dimple for alignment when installing a clamp on gas block...

Thanks guys. Based on some searching here on arfcom, looks like the popular opinion is pinned>clamped>set screw.

So, even though the barrel is already dimpled, it may still be better to clamp than set screw? Or, of course, I could go with the first post's advice and just pick the gas block and go with it regardless of whether its clamp or set screw.

Pinned. You do not want your gas block walking. If it does you now have a bolt action AR. If you cant go pinned get a clamp on. Set screw gas blocks scare me.

I have yet to have a set screw on a dimpled barrel walk. I use loctite on the set screws. Never a problem. I am not tier 1, but I use my guns.
