Luth-AR .750 Adjustable Gas Block – AR-15 Platform

The Luth-AR .750 Adjustable Gas Block gives you direct control over your AR-15's gas system, allowing you to fine-tune cycling for different ammunition loads, suppressor use, or to reduce felt recoil and carrier speed. This block is particularly useful for shooters running suppressed setups or handloads who need to dial back excess gas pressure that can cause over-gassing and accelerated wear on components.

Machined from steel with a durable black finish, this gas block fits standard .750" diameter barrels and features a set screw adjustment system for precise gas flow regulation. Installation requires removal of the existing gas block and basic familiarity with AR-15 assembly—while not complex, proper alignment and torque are critical for reliable function. A hex key is typically required for adjustment and set screw installation.
