Excellent Bolt
Bought 2 of these bolts! Initial inspection was excellent and they just feel slippery! I disassembled them both and the only thing I noticed is on one the cam pin was a little out of alignment rubbing on the gas key to remove it! Function is perfect; it only takes a little lift with thumb nail to pry it out. There is a real noticeable difference in smoother functioning of the Nickle Boron bolt over the mil spec bolt! Very nice bolt for the price! Would buy it again, 5 Stars +

Slick
I bought this for a build, the first time I slid it in it so smooth that I had to try it on another. It was just as smooth, I had had to buy another.
