**This is a revised/re-released version of the "AR-15 BCG Problems | KM Tactical" video**

This is Sarge here at C4 Defense, today I'm going to show you the problems I had when trying to run a nickel boron bolt carrier group I bought from KM Tactical at Wannemacher last year in Tulsa, Ok. Two of us got them and they bolt have failed to work. This KM Tactical BCG will not run reliably at all. I ran good for the first couple magazines, then it's had nothing but problems. The most it will run now is three rounds in a row, with multiple failure to feed and double feeds per magazine. The rifle used here ( https://youtu.be/2ZOnr7J-JbA ) ran fine with a Palmetto State Armory BCG both immediately before and immediately after this video using the same mags. I guess I'll have to strip this BCG down to see if I can find the problem, but don't expect this KM Tactical BCG to function out of the box. And as always, SUBSCRIBE, COMMENT, LIKE, hit that NOTIFICATION icon if you're already a subscriber, and we'll see you on the range.
