THE K-SPEC BCG COMBINES MULTIPLE KEY FEATURES FOCUSED ON INCREASING THE RELIABILITY OF YOUR AR15 STYLE FIREARM, REGARDLESS IF IT IS SUPPRESSED OR NOT. THE K-SPEC IS A TRULY PLUG-AND-PLAY BCG THAT WILL ACCOMMODATE WHATEVER CONFIGURATION YOUR MISSION REQUIRES. FOR THOSE RUNNING SUPPRESSED WEAPONS, THE K-SPEC ENHANCED BCG REQUIRES NO ADDITIONAL TUNING OR TWEAKING OF THE GAS OR RECOIL SYSTEMS TO FUNCTION RELIABLY. LIKE ALL KAK BCG'S, THE K-SPEC IS MACHINED TO THE M16 FULL AUTO PROFILE. IT IS MANUFACTURED FROM FORGED 7075 ALUMINUM, HAS AN NP3 FINISH ON THE DUAL EJECTOR BOLT AND BOLT/CAM PINS, ALONG WITH DOWNWARD GAS VENTS WITH ANGLED CARRIER RAILS. IT ALSO HAS A SATIN GOLD ANODIZED FINISH ON THE CARRIER.
