Very nice BCG

by -

I ordered this Bolt Carrier Group to go with a Melonited barrel I purchased a while ago. The finish on this BCG is very nice. The machining on it appears to be very nice also. The staking of the gas key seems very light. I think with a hammer and punch, I can make the staking marks a little deeper. Overall, I am very happy with my purchase. The shipping was very fast.

Fit to finish last BCG U need

by -

Whether U call it Ferritic nitrocarburizing, Tenifer or Melonite it all adds up to great finish on a great BCG. GunTec has manufactured a BCG with all the right touches and specs for firing even in the worst condition, currently -22° and never had the usual issue with gas or ejector sticking.
