Thread: Do you need an adjustable gas block when Suppressing an AR?

Hi guys, if its any help to anyone I have a adjustable gas block that I want to swap for a non adjustable one but it needs to be suitable for a .625 barrel. I dont run a suppressor and want to go back to a non adjustable. Or failing that buy a new one outright if someone has one for sale? Cheers

I have a question semi related to this, I want to suppress and get an adjustable gas block but I wondered what happens if I take the suppressor off on the odd day. Will I have adjusted the gas block in a way that my ar won't cycle or anything? Sorry if that's obvious I'm a newbie to the ar. Or am I best to adjust right down to where it's happy without the suppressor on first and just leave it at that

Yes.

Ok thanks @Banana
So pretty much adjust it and leave the suppressor on full stop

Nah you can have it set to run both in suppressed and suppressed

Yeah. I have a click adjustable block so it's easy to adjust between gas settings, but I don't use the gun unsuppressed. I would only consider swaping between suppressed and unsuppressed if you have a qd suppressor. A bare muzzle is pretty pointless, at least on shorter barrels.

You can, but it'll still be over/undergassed for both.

Has anyone tried an adjustable gas tube instead of the adjustable gas block for this??

I have, found it fiddly and would now always choose a adjustable block

Tried my first custom suppressor yesterday, looks like I'll be needing something to ease the gas off a bit.
