  1. Great bolt carrier super easy to clean 5 Star Review

    Posted by on 9th Feb 2015

    I picked this up based on a great recommendation from the guys at Atomic tactical. I had never really considered picking up a Nickel Boron coated bolt carrier. However I now fully understand how awesome these things are. I literally wiped almost all of the carbon build up off with just a paper towel. Save me a bunch of time during cleanup. I used this on my 10.5" pistol build, and you better believe this will be going in any of my future guns.


  2. Slicker than snot! 5 Star Review

    Posted by on 5th Aug 2014

    Used this WMD bcg on a 10.5" pistol build. Took it to the range to sight in, fired 100 rounds, 0 failures! This bcg functioned flawlessly. Used in conjunction with a Noveske KX3 flash hider, and Spikes heavy buffer. Cleaning was a breeze. I will be putting one of these in my M4 immediately! I highly recommend this bcg.
