This AR15 Armorer's wrench from AIM Sports is a steel, fully featured M4 gunsmithing tool. The AR15 tool features a number of specific applications for M4 rifles.
One end features an AR15 barrel nut wrench, while the other is a castle nut wrench. This allows for modification to the stock and the barrel. The notch on the side is designed for attaching flash hiders or other muzzle devices, while the small square is used to connect to a torque wrench for proper barrel installation.
These tools are a must have for anyone who owns an M4 and likes to tinker. They are perfect for use with some airsoft M4s, especially the KWA LM4 Gas Blowback Rifle.
