Works really slick - Griffin Armament Griffin Armorers Wrench

This worked great for getting the castle nut off my Windham rifle. I just put a 1/2 ratchet wrench in the square hole, and torqued away. When done mounting the new end plate, I put the wrench on the other side and torqued the castle nut back on. The edges on the wrench are clean and sharp, like they were cut with a laser. This is a quality tool for removing the castle nut. It's something to keep with your gun maintenance tools. The bottle cap opener is silly, but I guess the engineer had to do something with that extra space.
