Purchased this gas block for an over gassed, suppressed rifle. Once installed on the barrel, and set screws torqued, the adjuster binds so tight you have to have a punch and hammer to adjust. It was installed an a BA barrel, torqued to SI's specs. This was not any fault of Primary Arms, so I contacted SI's customer support. I was told this is a known manufacturing issue and would be covered under warranty, if I wanted to pay to ship it to them and pay for return shipping. I was also told by SI's customer support that "it's a great gas block, if you get a good one". I did not want to take another gamble if I would "get a good one", so I contacted PA who recommended I return it for a full refund. PA has hands down, the best customer service. I ended up going with a Bootleg adjustable BCG and never looked back. Thanks PA

May need a little more R&D.

I like the concept but the fit and function leave a lot to be desired. The adjustment wheel works fine until I actually tighten the gas block to the barrel, then it won't budge. I've only tried it on a Roscoe Mfg. barrel so results may vary but it seems like the clamp style was a poor choice for attachment.

Great product

Great gas block. Super easy to index. A few notes though. Upon installation the adjustment collar seems super tight and hard to turn especially under a rail. I was very worried about this but that issue resolved itself after actually firing the rifle. Dont really know how, maybe it broke in or whatever but the gas block is affixed nice and tight and proper yet the collar turns easily enough. IF you do not tighten the gas block BACK far enough to fully engage the detent then the collar is liable to disengage and either change settings or get caught between settings. I am using this gas block on a 300 blk that sees use with supers and subs.

Hard to adjust?


U have to set this about 1/16 off the shoulder at the gas block seat problems with adjusting if you do.
