The GEMTECH Suppressed Bolt Carrier is a drop-in replacement and will allow the shooter to choose between suppressed (S) and unsuppressed (U) settings without any permanent modifications to the firearm. No longer will you need to change gas blocks, buffers, or any other components. Not only that, but with the GEMTECH Suppressed Bolt Carrier, there is a reduction in carrier speed and less felt recoil, bringing the cyclic rate of the suppressed rifle down to unsuppressed levels. And in some systems, testing has shown that it can actually bring it LOWER than unsuppressed levels.

NOTE: This carrier is designed to operate with full power 5.56 and 300BLK ammunition, and will not cycle with subsonic ammo.
While it can be used for subsonic 300BLK, more reliable cycling is had in the Unsuppressed setting when using subsonic 300BLK ammo.
