KAK Industry has recently expanded on their hard-use K-SPEC bolt carrier groups with .224 Valkyrie/6.8spc support.
KAK Industry states “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.”
