Product description

Now you can get a proven Spike's Tactical M16 BCG Coated in Nickel Boron!

If you're looking for the finest BCG on the market today, search no more! This is the same Mil-Spec BCG that we sell but the only difference is that it's coated in Nickel Boron. And yes, it's High Pressure Tested and Magnetic Particle Inspected (HPT/MPI)

Nickel Boron has proven itself to be the most durable finish on the market. It's much smoother than Hard Chrome, it's easier to clean, makes the rifle cycle smoother, it can be run almost lube free for thousands of rounds, and it will never chip, peal, or flake off! Because of these benefits, Nickel Boron is being adopted by the Military as well as many Government agencies. As you can see, these BCGs are a huge improvement over a standard Phosphate BCG and it's even an improvement over Hard Chrome.

Upgrade to a better BCG today. You won't be sorry! BCG works in AR-15s.
