This tool, designed for AR15s, allows you to assemble or disassemble 13 different pins on the 5 major parts of the weapon. Made with a non-slip coating and moulded to the shape of the parts, you can work easily and comfortably to remove or install the pins. Each section clearly indicates which part of the weapon to place there and the size of pin punch to use. Avoid losing pins thanks to the 4 powerful magnets located in the block. Finally, there are also slots for storing extra pins or those you have removed.
