Classified Defense AR15 Castle Nut & Barrel Nut Wrench

A high quality wrench is critical for every AR15/AR10 build. This castle nut wrench / barrel nut wrench is critical to proper assembly and disassembly of PAMAX Tactical handguard and castle nut systems. PAMAX Tactical uses a low profile barrel nut which uses castle nut profile. This wrench by Classified Defense is crafted from quality materials and designed to offer flexibility and comfort during every build. The benefit to using a 1/2" drive ratchet is, you can properly torque the castle nut with a torque wrench during installation to overcome any staking. Further the tool is compact making it a must have in your range bag. We have testing this wrench on a variety of Mil-Spec Castle nuts along with the PWS Ratcheting Castle Nut and End Plate Set. In theory, this wrench will work with any castle nut that has the four slots like Mil-Spec or the PAMAX Tactical Barrel Nut.
