This is an excellent AR 15 front post sight adjustment tool for AR15, M4 and M16 A1/A2 front post sights. This ar 15 front post sight tool fits like a glove in the sight ramp. It is double ended, with 4 prong adjustment for the A2 sight pin, on one end, and the 5 prongs for the A1 sight pin on the opposite. It's made of high quality machined steel with black oxide coating to protect the steel and a nice knurled grip to help in adjusting your AR sights.
