This bucking is an epic failure. BBs get stuck and won't even chamber correctly because the nozzle end of the bucking is improperly sized. When I chambered a round with this in my L96 the bb's would get stuck and my APS2 240% spring (that's a 541 fps spring! ) couldn't even clear the jammed bb. I literally had to take the gun apart all the way down to the bucking in order to clear the jammed bb.
Prometheus also did a shotty job of shaping the nub on the interior, mine was torn on the right side and paper thin on the left side ( I could see light coming from the other side when I held it up to look at it).
Possibly a good candidate for use with an SCS bucking since it's thick and won't rip easily. But if it can't even chamber rounds, why bother?
-Gargantuan jams and weapon faults - the jams can't even be cleared by opening the bolt and sticking
an un-jamming rod down the barrel. You litterally have to take the gun apart all the way down to the
-Expensive waste of quality urethane.
-Mine came with a malformed interior nub
