Its only a minimal upgrade for my AK47 GearBox.
I got the AK47 (a swap for my old former friend TM AK47 ßeta Spetnaz)with PDI150 spring and already changed into CA Oiless Metal Bushing.
Ported the PistonHead and testing maybe i got the 400+fps. So i decided change it to stock spring and stock spring guide from CA g36, measured at the average of 330fps. fine!
after using the aeg more than two months, the screw holding the piston loosen and need to put some "thread lock", sealing the cylinder head with teflon tape...
chronoed again, 325fps? why? maybe the spring settle back after usages!
what i got here now, because i don't want to buy a new parts!...hmmmn...
the CA Aluminum Piston Head with Bearing bought from lyndon and a chikom "x120 spring" from kris g3 (replaced into pdi150 spring to her g3 equals 325fps only maybe because of some airleak)....
here i go again...
Comparison with TM stock (ported already) and CA aluminum piston head with bearing.
the new piston head
after polishing/cleaning the gears and the gearbox...putting a silicon grease from snyper...tnx sir!
returning back all the parts...
and chronoed again...
fine with me now, at least my AK47 at 1AD 350 fps limit...
Not bad for the responsible player like me... :-)
nice move sir scorpion.......
