Centurion Arms Low Profile Gas Blocks
.625″, .750″ and our .750″ tabbed for all current Centurion Arms barrels with the gas block alignment notch!
Carbon Steel Matte Black
*Does NOT come “pre-drilled” for pinning to barrel.*
Currently our gas block is the only one that Centurion Arms can guarantee to fit under the CMR. This is due to the CMR’s extreme low profile.
