Obsidian Arms Enhanced AR-15 Bolt Carrier Pin Kit

The Obsidian Arms Enhanced AR-15 Bolt Carrier Pin Kit is a replacement component kit designed to enhance the reliability and durability of AR-15 bolt carrier groups. Manufactured in the USA, the kit includes an enhanced firing pin, enhanced cam pin, and retainer pin. The firing pin and cam pin are precision-machined from 4340 alloy steel, heat treated for strength, and finished with a hard chrome coating to improve wear resistance, corrosion protection, and reduce friction during operation.

Suitable for routine maintenance, replacement of worn components, or new rifle builds, this kit provides key bolt carrier group parts engineered for compatibility with standard AR-15 platforms. The nickel-plated retainer pin offers additional corrosion resistance, while the hard chromed components are designed to withstand repeated firing cycles in demanding conditions.
