NiBx PSA BCG M16.

[Starcraftmlg]

I have a fairly new PSA BCG M16 that's nickel boron coated. It's got a couple rounds thru it. Wipes down clean and super slick! It requires minimal or no lube at all! Very awesome! I've upgraded all of my BCG to NiBx! Price is $185 shipped! Anyone know about PSA is that they are great and already $180 for a brand new BCG m16! Email is Starcraftmlg@gmail.com or PM me on here.

I can email pictures if needed.
