Superlative Arms AR-15 Adjustable Gas Block - Melonite - Set Screw - .625"

The Superlative Arms Bleed Off AR-15 Adjustable Gas Block gives you a near-endless range of tuning for a low-recoil, reliable rifle. Built for a .625" gas block journal, this set screw gas block bleeds excess gas forward instead of restricting flow, using only what's needed to cycle the bolt.

Features:

• .625" inside diameter
• Set Screw attachment method
• 416 stainless steel construction with a Melonite finish
• 30 adjustments
• Bleeds off excess gas rather than restricting flow
• Adjustment detent located outside the block to resist erosion and carbon seizing
• Includes set screws, gas tube roll pin, and hex key for adjustment
• Low profile: 1.259" height fits under most handguards
• Suited to suppressed rifles and SBRs

Because the bleed-off port vents excess pressure forward instead of holding it back, the rifle runs cleaner and cooler, with less blowback to the face. This version adds a Melonite finish over its 416 stainless steel body for extra wear resistance. The detent sits outside the block, so finding a setting doesn't mean fighting carbon buildup or screw erosion.

Superlative Arms draws on more than thirty years of aerospace engineering and manufacturing experience, applying that background to patented gas block designs for the AR-15 platform.
