Amazing difference! - POF USA .308 Roller Cam Pin Assembly RCPA308

Dropped this into the bolt on the AR-10 and I was initially skeptical, I fired about 60 rounds with it and didn't really notice much aside from a slightly different ejection angle (tad higher and more consistently placing cases in a smaller spot on the ground). When I cleaned my gun up, I dropped the factory cam pin back in and compared cycling (just by moving the bolt carrier by hand) and it was noticeably easier to pull out of battery and through the bolt stroke with the Roller Cam. From anywhere I've looked POF doesn't claim this as an attribute, but its pretty clear that it does move easier. Hard to argue with its intended claim though, its better to roll than slide...well, most times anyway...LOL!
