Breakthrough Clean BT-AR15AW Modern Sporting Rifle Armorer's Wrench AR-15

The Breakthrough Clean BT-AR15AW Modern Sporting Rifle Armorer's Wrench is a purpose-built armorer tool for AR-15 (and M4) platforms. Constructed out of durable titanium-plated stainless steel, this single-purpose wrench is designed to easily install and remove receiver extensions and castle nuts — the two jobs it is most often called on to handle during stock swaps, buffer tube changes, and armorer-level maintenance. The titanium-plated finish provides long-lasting corrosion resistance, and the dedicated wrench geometry seats and drives castle nuts without slipping or marring the receiver. Finished in Black, the BT-AR15AW is a compact, bench-ready tool every AR-15 builder and armorer should keep within reach.
