Have a elite force UMP45 ELITE that I bought back in November and immediately dropped a F2 in it. The Gearbox I used for the F2 was not the one that this gun came with so the Gearbox and Motor is unused And unopened aside from just test firing the gun. I disabled blowback when took the Gearbox out because I stretched the springs (whoops!) however I will include the parts should you wish to make the blowback function. Truthfully it’s better without it because you can fit bigger batteries in it without the blowback mechanism in the way. Anyway, the gun shoots great, has a QC spring guide, an electronic trigger board so it has safe, semi, 2-round burst, and full auto. The HK slap on this works. Has full HK trades. Stock folds and locks into place nicely. Has a 6.03 tightbore barrel in it as well as a G&G bucking with M nub. Has a 14mm CCW threaded outer barrel. The bottom of the pistol grip has a section drilled out for when I ran the HPA F2 in it. This has absolutely no effect on performance as it’s a V3 Gearbox so the Motor is alligned and adjusted directly on the Gearbox, not by the grip screws. Comes with 5 mid caps and 1 hi cap (hi cap not pictures) as well as the pouches pictured. I have the tops for the pouches I can include them too I just found it easier to run it open top. Can produce any shooting tests upon request. All the upgrades and extra mags and pouches were over 400. I am Asking 275 OBO. Shipping will be roughly 20$. Thanks for looking have a blessed day.
