H&K Licensed Umarex UMP build
ASG motor, 13:1 gears, all air seal parts upgraded, stock mosfet w/ burst fire, upgraded barrel. Fully built indoor gun but could be sprung for outside. It is quick change spring.
This was my go to indoor gun, super light weight, super snappy.
Includes everything pictured including the mag holder since these mags can be difficult to shop for holders.
Has a really nice strobe/flash light and tracer/ muzzle flash unit.
