Specifications

UPC: 855319005501
Manufacturer: Spike's Tactical

Description

This Spike's Tactical Bolt Carrier Group is the same Mil-Spec BCG that they sell but the only difference is that it's coated in Nickel Boron. It is 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. This BCG works in AR-15s.
