JM J12 AK74U - Plenty of Pew for your Penny
More of an SMG than an AR.
Good weight, slim, balanced, metal parts and heavy duty nylon and quiet for 250+ fps OOTB.
Impressive build, easy to strip although 4 bolts to hold detachable front end is overkill.
Everything is easily removable including plate that houses the mag contacts.
Trigger feels good.
Wiring is minimal and tidy.
25cm 7.5 plastic barrel
T-piece is custom.
Solid gearbox shell.
Large capacity mag held on by a lip and not inserted, fits firmly with no play.
Non-descript motor is adequate but will not pull anything stronger.
At current prices, this is plenty of Bang for your Buck.
See through gaps in battery cover (use plastic sheet provided).
Flash hider goes CW onto a thread adapter that is CCW onto 14mm outer barrel. Tightening one loosens the other.
Mag springs both bent and not making contact.
Shot selector is flimsy, needs to be pulled away from shell to move and is held on by a tiny screw under a little cap that comes off easily.
Pistol grip is nicely textured but child-sized.
Open sights are tiny and close together like some pistols and too far forward to be practical.
No mounting rails athough removable side-mount adaptor is provided.
Seal check although stock fps suggests it’s good
Metal barrel 7.2 or 7.3, length to be decided
Spring tidy-up plus gen9 spring guide.
Spring upgrade depending on effect of tighter barrel. Closer to 300fps is adequate
UV LEDs, naturally.
Stabilise barrel in outer barrel
Hop up. Have to remove unthreaded section of outer barrel front end as it gets in the way of most threaded hop ups.
Something about that shot selector.
