Outerwild Manufacturing produces our M16 BCG which is trusted by seasoned shooters and depended on by experienced builders. Our goal is to go above and beyond Mil-Spec expectations! Outerwild’s secret sauce: PRECISION GROUND. We machine and grind our BCGs to perform for tens of thousands of rounds. We grind the outside dimensions and ALL three interior dimensions of our carrier, giving our BCGs a near frictionless surface finish. The polished nickel boron coating is applied by the industry leading plater, WMD. The NiB-X coating provides a very slick surface that makes for easier cleaning and increases reliability. Properly built, no corners cut.

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.
