Spike’s Tactical Adjustable Low-Profile Gas Block, .750 Features
The Spike’s Tactical adjustable low-profile gas block bleeds excess gas out of the block rather than restricting flow like a conventional adjustable block, so the gas adjustment screw doesn’t erode, seize, or lose its detent from carbon buildup. It’s especially useful on suppressed rifles or SBRs, where added back-pressure can cause over-cycling; dialing the gas down restores normal cycling behavior and reduces bolt velocity. Pair it with a Spike’s Tactical carbine gas tube, or browse our full selection of adjustable gas blocks.

The .750″ bore diameter matches the most common barrel outer diameter at the gas block seating area on government, M4, and heavy-profile AR-15 barrels, and on many .750″-journal AR-10 pattern barrels — confirm your barrel’s outer diameter at the gas port before ordering. Installation requires sliding the block over the barrel to the gas port location and securing it with the included set screws against the barrel’s dimples.
