Superlative Arms AR15 .625in Clamp-On Adjustable Piston Gas Block

Superlative Arms AR-15 .625in clamp-on adjustable piston system featuring a piston gas block with mid-length op rod, left-hand configuration.

Key features:

• Reduces gas pressure only to the amount required to drive the bolt carrier; remaining gas is bled off to run cleaner and cooler
• Reduces wear on the bolt carrier group components and upper receiver
• Reduction of felt recoil for faster follow-up shots
• Patented adjustment detent located outside the block to help prevent contamination
• Bleed-off mode: the adjustment screw does not restrict gas flow, reducing erosion/seizing and helping prevent detent loss from carbon buildup
• For SBRs and/or suppressors: bleed-off port exhausts excessive pressure out of the block to reduce blowback
