855319005501 Matched bolt/carrier set is machined to mil-spec dimensions using the latest manufacturing and quality-control techniques to deliver superb reliability in both semi-auto and select-fire rifles. Carrier is hard-chromed inside and has an M16-type full-length shroud on the underside to trip the auto sear on full-auto/burst rifles. Bolt is magnetic particle inspected to ensure there are no internal flaws to compromise structural integrity and cause premature failure. Fully staked carrier key and tool steel extractor further aid reliable cycling. Laser-engraved Spike’s Tactical logo on the side of the carrier is visible when the ejection port door is open. .223/5.56 fits standard AR-15/M16/M4 rifles and is available with a FailZero EXO™ nickel-boron coating that’s smoother and slicker than hard-chrome for reduced friction and superb wear-resistance in high-intensity applications.

Brownells USA headspace problems with this BCG 19/10/2015

The ni-boron is not applied evenly and all moving parts are very tight. installed with a new rainier match grade barrel and there was inability to close on a forester go gauge and would not chamber a new factory .223 round.

in speaking with a gunsmith he said the Spikes tactical ni-boron BCG has had this problem before.

I'm returning for a different manufacturer...Thanks to my Brownell Edge

Definitely recommended

Brownells USA Tested and Approved 19/05/2015

I bought a couple of these to test out for a couple builds that I was doing. I have to say that they are far better then the PSA NB BCG and right up there with the wilson combat ones. I have beaten the this BCG in full auto without issue. Buy this one.
