WMD Guns Buffer Tube Carbine NIB-X Silver – AR-15 Mil-Spec

The WMD Guns NIB-X Silver Carbine Buffer Tube is a mil-spec receiver extension designed for AR-15 carbine-length stocks. This buffer tube replaces standard mil-spec tubes and features WMD's proprietary NIB-X nickel boron coating, which offers exceptional hardness, corrosion resistance, and self-lubricating properties. Shooters who run their rifles in harsh environments or who want reduced friction during stock adjustment will appreciate the NIB-X finish over standard phosphate or anodized tubes.

Manufactured from 7075-T6 aluminum with a durable NIB-X silver finish applied to all surfaces including the threads. Installation is straightforward for anyone familiar with AR-15 lower assembly—requires a castle nut wrench and staking tool for proper installation. The mil-spec diameter ensures compatibility with standard carbine stocks from all manufacturers. Threading is precise and the finish is uniform, allowing smooth stock movement without binding.
