    Best BCG I have ever used in a .308 build. Very smooth finish.

    Paired this bad boy with my Aero M5 upper. 5000+ round. So far so good. Very high quality and very easy to clean.

  • Nitriding on carrier is garbage

    Posted by William stebbins on 18th Nov 2021

    I just bought this bolt carrier and after 100 rounds the nitride on the front bearing surfaces is already gone. Like real bad! Do not buy this bcg. It's like it's a spray painted coating rather than a real nitride job. I will be sending this back for a refund as soon as I find a replacement.
