Strike Industries Collar Adjustable Gas Block

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

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 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.

U have to set this about 1/16 off the shoulder at the gas block seat ..no problems with adjusting if you do.

Not sure what they mean by “if your lucky to get a good one” cause I’m not lucky but mine works great!! 300 Blackout subs I open it WFO and supers 2 clicks shut and my 10” pistol runs perfect with out a can for now!

I have read negative reviews however installing per directions this unit is working flawlessly and adjusts as advertised.
In use on: 10.5" kak 9x39 barrel
Ammo: Wolf 278 gr fmj subsonic

After installing per instructions this gas block works perfectly as advertised. I can see if operator error on install will malfunction. I use this on my 9x39 and works flawlessly.

Got this to try out and works similar to the Govnah, which is excellent. Adjustment ring is easy to use and easily accessible. I've used SLR's, SA's, and some other adjustable GB's and I like the SI as much as any of the others.

I ordered on of these gas blocks and it works great.. There isn't any installation instructions so if you have any questions YOUTUBE.com has a video on how to install it. There is a tiny set screw that locks the adjuster in place before you install the actual gas block. That makes it easy to line it up with your gas port on the barrel. I hope this review helps anyone looking to buy this product. It's well worth the money.

This gas block was worth the money
You can quickly adjust with either your fingernail or a pointy object such as a flathead screwdriver if you handguard permits!
**NOTE**
Make sure to follow directions, you can run into trouble and it CAN be very hard to adjust if its too tight against the gas block flange on the barrel. If the Adjuster nut is too tight against the gasblock flange on the barrel it will be crazy diffcult to adjust. I had to install it twice jusut to get it right. Oil it all up. Also lube up the barrel flange where the gas block adjuster nut sits against. a Good video is online

Set the ADJUSTER nut with the alrgest port size over the gas port then set it with the small single screw. Not the gas block setting screws. Once the adjuster nut is set with the largest port size over the gas port, then install the gas block itself over it. ENSURING proper fitment! Give it time to break in as well
