H&K UMP Competition Series Airsoft AEG Rifle by Umarex (Color: Tan)

"Fairly good gun for a while. I don't put much wear on my gear, but the bottom rail mounts are now stripped after taking it off twice. It fell of on the field, but I was able to spot it. I could superglue it, but it'd be a challenge to put anything on the bottom rail, seeing as you can't slide anything onto it.
Pros:
Cheap
Solid Feeding
FPS is low enough for CQB and high enough to use on fields.
Metal Rails
Cons:
Iron Sights too low
Polymer body is weak
Non-functioning charging handle
Only Hi-Caps
No barrel threads

All in all, it's an okay starting gun, but there are some much better options out there for SMGs.

"This was my first skirmish ready AEG and I am not too happy about it. It was good for $160 but there is just some things that could've been better.

Pros:
Sound is pretty loud, but nothing to get so excited about.
Polymer is high quality and is lightweight without being cheap.
Stock folds easily and unfolds easily.
Hop-up is easy to adjust.
Good battery compartment size.
Quick change spring system
Cons:
Charging handle does not work (minor)
Only hi-caps are made (Con to me but might not be for you)
Accuracy and range is ok
ROF isn't good for a smg.
Sights are too low for use of a mesh mask or paintball mask.
Trigger assembly and fire selector are loose.
Trigger response is ok.
Battery compartment door broke.
At first I couldn't put it back together.

I would not recommend to a guy that can't do upgrades, because there is many things to be done to this so it can be a good smg.

"Ok so when I took this gun out of the box I can till it was cheap made by looking at the sight, good weight though.
The wired for the battery department can bend easily, also the wired look cheap also.
I took it outside to shoot and the gun had trouble feeding for some reason even though the mag feels tight inside of the gun.
This gun is very sensitive just in general.

this is by far the worst SMG airsolf I've ever gotten, I might as well by a FN Herstal p90

"This gun is simply OK, my son loves it though. It is not worth $170. I would not buy it again. The magazines do suck, the trigger does suck, and the overall quality is poor. The battery door is a major problem, if the stock starts to fold with the door open, it will break, as my son proved. I should have gone with the G36C, in retrospect this gun is total garbage.

Also the magazines require a special pouch, so there was $30 right there.

Total garbage. Avoid.

"I'm a G&G and KWA player so i'm used to paying a bit extra to ensure high quality. This replica is a good example of "you get what you pay for". I got this thinking that since HK was involved, quality would be great. That wasn't the case.

Out of the box the plastic felt extremely cheap. I slapped a foregrip on the front and did some room clearing and the lower rail ripped through the plastic and broke off the gun. I had to bolt it back on since it hollowed the threads in the cheap plastic. This may not be a con for most, but the mags are much larger than they look, and really get in the way. The gun itself is extremely heavy for having a mostly polymer build.

The hinged stock is a nice feature but feels flimsy. The back door to the battery compartment is very thin and cheap plastic that bent easily.

The trigger has a disappointing long pull and is not immediately responsive. This coupled with the low rate of fire make shooting the marker unsatisfying and pretty boring.

The sights are decent. The quality of the mags are decent, but you need to allocate alot of space on your vest since they're so big. If you're looking for some backyard fun once in a great while, sure. If you're a serious or more active player, stay away.

OVERALL:
Save your money and get a different replica. I could probably go to my local Dick's Sporting Goods and pick up a better AEG off the shelf. If you must have an SMG, go for an Echo 1 MP5 or something else. Regretful purchase but lesson learned on my part.
