Fits loose - Griffin Armament Griffin Armorers Wrench

Only 2/3 of the tooth grabs onto the castle nut and you have to be super careful tightening it or else it'll slip off. The muzzle slot is loose and has a lot of pla. Probably not a good idea to torque anything down with this, Just snug tight. Great tool to have if you're with your friends and they need to work on their AR and borrow your tool so you give them this cheap one and use the expensive one for yourself.
