SOLD Umarex/S&T HK UMP 45 Upgraded/Extras

PRISTINE CONDITION Umarex/S&T HK UMP .45 - Internally upgraded, the gearbox cylinder housing has been radiused and the piston guide rails polished, steel rack piston, ASG 16.5:1 gearset, Prometheus M90 spring giving a consistant 310 FPS.
Ultimate ported cylinder, bearing piston head, modified tappet plate for air seal, steel bushings, and anti reversal latch with Prometheus shims.
Gate Nano ASR with deans connector.
Maple Leaf Super Macaron bucking.l with Omega nub.
Weight added internally so it doesn't feel like a toy as much.
The rear battery door has been removed to better accomodate batteries - this is still a very tight compartment, but a 7.4v 1300mAh Vapex LiPo fits perfectly. The crappy plastic outer barrel has been replaced with S&T metal barrel and modified to take a G&G steel muzzle for B&T QD suppressor. The front/rear sight pins and trunion pin have been replaced with roll pins like real steel instead of the solid steel pins that came with the gun.

The "bolt" has been painted a more realistic colour. Begadi Mid cap and S&T high cap mags included.

The gun has a replica C-More red dot sight on top. €280 posted in box.

Will consider trade for equally pristine Ares/CA HK G36K working or not, but MUST be in excellent condition.
