are you reading off a script? nice product though. looks really nice.

kinda pointless as the air in the chamber escapes through the center of the bolt as it returns with spring tension. seems more likely that the other bolt on the other carrier simply has it's o-ring binding along the inside surface of the expansion chamber. after changing out that red soft silicone o-ring with a black nitrate o-ring of the correct size, my RA-Tech bolt returns just as fast as this "new" one. but hey, what do i know.
