Over a year ago my youngest son spent his own money on a used AKM being sold by a local shop's staff member, which on paper looked sweet, however it was very unreliable with the Perun optical controller just craping out every few shots. Finally bad Dad has sorted it out and installed a GATE Titan v3 and a 27k Warhead brushless motor, with it now running very well (especially on full auto).
With it having now been worked on by me I've taken a few photos that were interesting and have a few questions for others.
When he first bought it and when it did work, for the first few shots, it had great range and consistency and a few things probably helped this in that there's a 3D printed block keeping the hop unit steady, the inner barrel has PTFE tape wrapped around it, and there's also a sliver of a tin can and masking tape below the inner barrel at the front of the receiver (all of which I suppose kept things very much in-place). Is this all a smart thing to do with an AKM?
It's no specific brand either, it's very much a mongrel. The gearbox is CYMA, and like a boneyard CYMA MP5K I sorted out there was this awful thick green grease in it which I had to clean out. The receiver and wooden furniture is a bit of a mystery, I've no idea where the wooden furniture is from, however the receiver says on the bottom it's APS and the front left of the receiver has painted Russian symbols and numbers.
