Home Forums Hunting & Shooting AR and Tactical Rifles Adjustable gas blocks

I've got one of the superlative gas blocks on a Ruger sfar in 308. got rid of the factory gas system. I have this thing on the pass-through mode bleeding as much gas off as possible. I have not put a suppressor on it but I don't see any reason why it wouldn't work fine except it might be a little overcast from what I'm seeing right now.. if that's purely guessing

I'll test it and "tune" it tomorrow.

I have a handful of SA gas blocks, they're generally my favorite style. One interesting thing about bleed off mode is that it can reduce sound at ear suppressed. Here's a post from a while back by a dead air engineer showing some metering data.

Yeah, this and blowback reduction are my priorities. My son shoots lefty, so it makes an even bigger difference.

The best gas block I've found is the SLR. Easy to adjust, easy to take apart & clean (by design), holds setting & very well made. Easy to change settings & then go back to the original setting.

Generally, a better AGB, in my opinion...............I have quite a few.
