Spikes Tactical BCG W/ Nickel Boron Coating
by Dan C. Watkins
After years in the US Army (now retired) and having had BCG's in M16 that always seemed to get so horrible dirty after shooting on ranges. I wanted to make life easier for me with my Ar15 at home. The BCG coated with Nickel Boron is like nothing I've ever dealt with before. It is truely awesome and can be cleaned almost just by wipeing with a clean rag. A must have for anyone who's concerned with making easy in the cleanup after firing!
BCG
by Devonson Martin
Always a pleasure going to primary arms.nice quality bolt carrier group for your money.
Looked good...
by CW
BCG looks good, slightly different than the last Spikes NibX I got, different machining/look... But still a quality piece. The first I got was missing a gas ring and the remaining rings were damaged, but PA took care of me... This BCG came complete, but has more of a rough overall appearance. Happy with it though.

Excellent service as usual, fast delivery!
Disappointed
by Nicholas Case
Finished my build and put it in and it was great, until I function checked. When I let the hammer fall it jammed, would not extract and the bolt would not rotate even with heavy lube. Took disasembly and force, tried it in factory Colt, DD, and Stag. Same prob. My BCM bcg works fine in my build, but wanted NiB. The part I got seemed to be machined to the wrong specs (I know that FailZero coats some of these products, and I read a post by their head gunsmith that stated that if the bcg does not fit you need to have your headspace checked that it is not match grade and is instead mil spec as these bcg's are patterned after Colt style rifles... But it would not work in my colt?). Returned to PA for refund. They are out of stock. How does that even leave Spikes Tactical not functioning? I have to add that PA is still the great. They handled it well, gave me return shipping labels and a full refund. I will try another when in stock.
