The K-SPEC BCG combines multiple key features focused on increasing the reliability of your AR15 style firearm no matter if you are running suppressed or unsuppressed, and regardless of conditions. The K-SPEC is a truly plug and play BCG that will accommodate whatever configuration your mission requires.
For those running suppressed, the K-SPEC requires no additional tuning or tweaking of the gas or recoil systems to run reliably. Like all KAK BCGs, the K-SPEC is machined to the M16 full auto profile.
