Optic shown in images not included.The H&K UMP (Universale Maschinenpistole, Universal Machine Pistol) was developed and manufactured as a lightweight and cheaper to produce successor to the venerable MP5.The UMP utilizes high tech polymers for the great majority of the firearm to help cut down on overall weight as well as make the firearm less susceptible to the elements and corrosion. Other features include 4 different trigger group settings (safe / semi / 2rd burst / full auto), a side-folding buttstock to help reduce the weapon profile for transport, Picatinny accessory rails, and a bolt lock which will engage after the last round is fired.

The UMAREX gas blowback UMP features realistic construction and functionality that replicates the actual UMP as closely as possible. The sturdy polymer receiver and front assembly helps make this SMG incredibly light weight, perfect for high speed loadouts. The UMP boasts very realistic recoil and an impressive fire rate that can quickly empty its realistic 30rd magazine, putting a lot of firepower down range.

"Ok to start off the review I am VERY biased towards the UMP-45 in general just because of looks and it's place in movies such as Casino Royale and Quantum Of Solace. That being said, this is a very nice gas blowback SMG. This thing has some GREAT RECOIL and once the hop-up and rear sight were adjusted properly, it shot very straight. I did have a slight problem with the magazine though but it was fixed after I let all of the gas out, let it warm back up, and re-gassed it. The only con about this gun is the magazines are a PAIN to load even with the speedloader. Other than that, I removed all the rails and the handstop and am planning to buy the G&G UMG mock supressor for it. Overall, I rate this gun a 5 out of 5 and it would be a fun CQB or Outdoor gun for the gas blowback enthusiast such as myself.

"I got this from a trade and the previous user took extremely good care of it. He told me he had this for about a year and a half, and rarely had a chance to use it due to his location.

The gun is built from a stronger type of polymer compared to the standard non-blowback version. It is very light weight and anyone can use it. The magazine holds around 25-ish rounds, and it's very hard to load bb's in even with a speed reloader. Firing mode comes with safe, single, double, and full auto; honestly 2 round burst works best for me in face-to-face combat. Gas consumption is moderate: I usually get about one and a half mags worth of bb's with one fill of propane. The abundance of rails on the sides allows you to customize this the way you want: I have mine decked out with an (replica) EoTech, foregrip, and the G&G UMG Silencer (The UMG silencer is not a 100% fit, but it clips on the barrel to the point in which it does not wiggle around. Highly recommended if you're looking for a silencer!) Overall, I love this a lot and I thinks it's a little bit under rated, but this is merely my opinion. Best of all, you can do the HK slap!!

"Update to my previous Review:
After tuning the hopup a bit more and allowing it to break in, I decided to take it to my local indoor arena.
Oh boy, this gun was fantastic. The building was room temperature, about 70˚F, and using a 6 second gas fill I got 2 mags worth on semi, which isn't that bad thinking about the rapid semi shots that occur in cqb.
Everyone noticed the loud "clank" noise every time I fired a shot. This thing is LOUD inside.
The only con was that the official field chrono readings were as follows:
w/ .25g
375.6 FPS
365.2 FPS
This gun may be a bit hot for some places without an NPAS or a quick mod, however I got lucky and my indoor arena has high FPS limits.

Still a 10/10!
