ProMag PM249 Carbine Stock Wrench Black Oxide Steel Rifle

The ProMag PM249 Carbine Stock Wrench is a multi-function AR-15 gunsmithing tool designed to handle the most common assembly and disassembly tasks on your workbench. Built from durable carbon steel with a corrosion-resistant black-oxide finish, this tool consolidates several essential functions into one compact package — eliminating the need to hunt through your toolbox when you're building your first AR or performing maintenance on rifles you already own. Whether you're a first-time builder or an experienced gun owner working on multiple platforms, having the right tool for the job makes the work faster and more reliable.

This wrench handles four distinct tasks: castle-nut wrench function for stock and buffer-tube work, receiver-extension removal capability, A1/A2 flash-hider wrench function, and a bottle opener for the range or shop. The black-oxide steel construction resists corrosion and is built to withstand repeated use without wearing out or stripping. Made in the USA, the ProMag PM249 is the kind of tool that earns a permanent spot in any serious shooter's maintenance kit.

If you're setting up an AR-15 building station or just tired of improvising with the wrong tool, this wrench pays for itself the first time you use it. It's compact enough to store easily but substantial enough to do real work without flex or failure.
