Patent Pending

This BCG enables you to run a standard 3 oz standard carbine buffer instead of H buffer weights with an FRT.

There is a floating weight in the carrier tail which has a dead blow effect eliminating bolt bounce, and providing enough weight for the FRT to function as intended. 

We have tested this successfully with the Hoffman Tactical Super Safety, AS Designs ARC fire FRS, Atrius Development FRS, and Rare Breed FRT. Similarly designed product should work as well.

    I love it!

    I was tired of trying to fine tune my 300 blackout to run with a trigger kicker. I swapped the kicker out for a super safety and it ran ok but still had problems with subs after numerous springs and buffer weights. I threw this in with carbine spring and h2 buffer just because and I have no complaints. GET ONE! I shoot suppressed and was told a down vent was the better option but I have no issues

    The Triggered Company's Disruptor FRT drop in trigger group didn't work with a H3 5.4 oz buffer....but worked like a champ with this KAK BCG. Nothing but praise from me!!! Easy FRT tuning with one try. AWESOME!!!

    If you’re looking for a no guess way of tuning any AR with a FRT, THIS IS IT!!! I use these on multiple barrel lengths from7” to 16” and the FRT works perfect. These DEAD BLOW CARRIERS are the answer to so many issues!!

    Solved everything

    5.56 Carbine has been driving me nuts trying to get an FRT to function and was about to give up. Found this, ordered, dropped it in and ran flawlessly.
