Not familiar with the Reaper II. Is it a single or a double solenoid engine? Can you adjust dwell times on it? Could this maybe be how fast/hard the nozzle hits the bb during chambering? Are the BBs you’re using cheap grade bbs? YOu’ve checked the nub and the adjusting arm, and it’s oporating correctly?
Wolverine Reaper II HPA engine over-feeding problem
Been banging my head on an MP5SD build with a Reaper 2 HPA unit from Wolverine; some BB's hop normally, some underhop, and some roll out the barrel.
I've pinned it down to BB's getting pushed too far into the bucking sometimes. However, it isn't the length on the nozzle doing it as it mechanically cannot push BB's in that far.
Alignment on the barrel/chamber is good, compression is good (the nozzle seats all the way to the bucking lips), and I've tried several buckings and even an o-ring around the feed lips to add a bit of extra reinforcement to slow the BB down...
There doesn't seem to be any mechanism to keep the nozzle from just golf-teeing the BB's past the bucking lips and bump, so it seems to just slap the BB hard into the chamber. An AEG tappet plate has a fin that lets it in slowly, so I'd be tempted to call this a design flaw, but other folks use these without fuss (I think...), so the problem must be with mine.
Any ideas or is this just a poorly-designed engine?
