BLACKNITRIDE℠ Processing:
Reduces the need for oils and
greases – making it optimal for
operation in arid environments.
The best BCG money can buy, IMHO.
I have NiB (Spikes, FZ, WMD) BCG's as well, and this RCA is a better-constructed unit. I have replaced all BCG's in my DI guns with these RCA's -- Colt, LMT, BCM. Only my GP gun (an Adams Arms all-Melonite upper with similar Nitride BCG on a Seekins Billet Lower) has a BCG other than RCA.
These things are very slick. I highly recommend them.
