  1. Best bolt carrier for your semi MG42 platforn. 5 Star Review

    Posted by on 18th Sep 2015

    I like the fact these can be "tuned" via washers for specific ammo. I had to do a little trimming too in the rear lower area for hammer clearance ...something that should be expected in this type of semi build.

    Both of mine built using these BRP parts run about 99% using good surplus SA .308, about 97% with 8mm surplus ammo; with a rare light primer strike, maybe one per hundred, which is good enough for me for this type of semi converted belt fed.

    Another "tuning" area often over looked can be booster sizes and recoil springs which also play a huge role in reliability with these.

    Keep your build (receiver) straight, with barrel and rails bind free as well.

    To sum it up...this is the bolt carrier you want for you semi build.
