JP Low Profile, Non-RailedAdjustable AR15 Gas Block System .936 BoreAllows tuning the AR15 bolt velocity to reduce bolt slamming, manage recoil, and increase accuracy potential. The JPGS-8 model gas block is our low profile large bore (.936 dia) model with a non-railed design to fit under extended handguards. This model also now includes our locking adjustment feature, which consists of an integral set screw that can be tensioned against the adjustment screw after it has been set to prevent any migration that might occur.
The installation of this gas block requires use of a 6-32 H1 or H2 bottoming tap. If you do not own such a tap, you can add one to your order at right. Click the link to the JPGS-8 instruction sheet below for more details.
