This is the second jp enterprise adjustable gas block i have bought. The first was a new build . And this one is a upgrade to a dpms lr 308. Work great to tune the recoil and cycling of the weapon. To change the rail on lr308 you have to change out gas block. For the money to quirky this gas block is hard to,beat.

Great Product. Fit perfectly under my Aero Precision Rail on a Seekins Barrel.Comes with a long Allen key to adjust the block without removing the hand guard. I did not need shims or any extra parts.

The Jp low profile gas block slid onto my barrel smoothly and was easily able to align it with gas port and get it clamped onto barrel nice and snug. The adjustable set up seems to work well after you get it tuned allowing the right amount gas to go through to push the bcg back enough to be reliable. Chose the stainless bead blasted matte finish to match my furniture and controls on my custom rifle build. It was a tight fight but it fit perfectly under a 16” fortis night rail just had to be careful sliding the night rail over the gas block and onto the barrel nut in order not to come in contact causing possible scratched on the finish of either part. the only issue with it I have is the placement of the adjustment screw. It may be only an issue due to the handguard i have on my rifle and jp does warn that it may not be accessible on other free float handguards other than their own but wish they would of came up with a way to make it accessible from the front of the gas block and placed the the set screw holding the adjustment screw secure on the side about 1/4 inch further to the front. Not sure if that would help make it compatible with other free float handguards but would make it accessible on the night rail. Since thats probably a personal issue with the rail i have and they warn that it may not be accessible with other free float rails besides theirs im not deducting any stars for it. its still usable on my rifle just a little more of a hassle having to loosen the barrel nut n slide the rail forward a little bit to be able to access the adjustment screw to tune it but once it’s tuned you probably wont have mess with it after that unless you need to adjust the gas later on for some reason.

Quality product and very well machined, would definitely buy again!! It was to big for one of my rifles handrail but I was able to use it on another build! The clamp on feature is best for barrels with no predrilled detent hole if you don’t wanna drill some yourself

Set it up on a shorty 300 Blk build and set it up about 4.25 turns out and runs perfectly with 147 grain and cycles reliably with 208 amax. Only problem is, the profile is a little too large for my m lock handguard where the set screw hits the handguard. Just had to shave off .080 thou off the top of the set screw, where it will still turn reliably and it works just fine now. Still gave it 5 stars cause I should have checked dimensions for fitment. Would buy another.

For the price it would not have hurt them to drill out the set pin hole. And include a dab of loctite. Any way optics planet split up my order into like five shipments all different delivery dates. One as much a a month out….
