Love it or hate it, I've decided to plunge into the deep end and build of building a rifle out of an AAP-01 after being away from airsoft for about 5 years...
It's still work in progress with some tuning required but one consultant issue I am having with it is that on full auto the bolt binds half way, doesn't rack back and if I push it forward into battery, it vents the mag, this tels me it's not cycling back enough for the hammer knocker to reset.
It's not limited to full auto though, if on single and I hold the trigger, I can feel the difference in how much it's binding when I rack it back slowly and it won't go fully back to battery without assistance, if I rack it normally and let the recoil spring take over then it sometimes seats fully but not always, with the limited internal upgrades at this time I know it's restricted to either the bolt, short stroke kit or the trigger (I'm leaning to the trigger)...
Anyone come across this issue before? I would like to rectify it before doing any other internal upgrades to prevent any unnecessary wear or strain on components.
Installed internally at the moment is as follows (there will be more in due time before she is ready for a game)
Carbine kit W/TDC hop
Cow cow light weight bolt
Cow Cow short stroke kit (1 buffer added)
Charging handle w/ fire select
waiting to be installed:
270mm maple lead crazy jet barrel
Crazy jet 60° autobot rubber
Annoyingly yes... the rail doesn't sit flush with the upper, this is due to the barrel nut not going in far enough, just trying to figure out a solution to this without too much metal work lol
