Title: A1Armory .223/5.56/300BLK M16 Nickel Boron Bolt Carrier Group - Premium Firearm Performance

Description:

Enhance the performance of your firearm with the A1Armory .223/5.56/300BLK M16 Nickel Boron Bolt Carrier Group Complete Assembly. Crafted with meticulous attention to detail and precision engineering, this bolt carrier group is designed to meet and exceed mil-spec standards, ensuring reliable and smooth operation.

The 8620 M16 style carrier undergoes a rigorous process, including heat treatment, shot peening, and relief cutting, resulting in a component machined to exact mil-spec dimensions. The UCT EXO Nickel Boron Coating provides superior lubricity and wear resistance compared to regular nitride coatings, facilitating easier carbon cleanup and ensuring long-lasting performance.

The Carpenter 158 5.56/.223 bolt, featuring heat treatment, shot peening, and UCT EXO Nickel Boron Coating, is paired with a 4140 billet gas key. The gas key, also coated with UCT EXO Nickel Boron, is properly seated with Grade 8 fasteners and staked to guarantee reliability. The 4140 cam pin, heat-treated and precision ground, along with the billet extractor made from 4140 steel, ensure durability and dependable extraction.

The firing pin, precision machined from 17-4 H-900 stainless steel, further enhances the overall reliability of the assembly. The entire unit is 100% USA made, reflecting a commitment to quality and craftsmanship.
