PRI’s Low Profile Adjustable Gas block is a perfect option for those looking to configure their rifle for absolute best performance with their chosen ammunition. Adjustable gas blocks are a huge improvement when it comes for suppressor use or irregularly demanding conditions. The PRI adjustable gas block gives all the control to the user without the massive footprint that some adjustable gas blocks use. Made from 1141 high strength steel with a magnesium phosphate finish, this gas block is a perfect fit for .750 diameter barrels.
The gas block is secured with 2 10-32 set screws and is 1.38” tall, 1” long, and is .625” from bore center to gas tube. Width is .92”, and distance from back of the block to the gas port hole is .250.

This leaves .035 between the back of the gas block and most steps in the barrel for A2 handguards. This space can be filled with a spacer or left empty to shooter preference.
