Evike.com Exclusive H&K Licensed USP Airsoft Electric Powered AEP Pistol by Umarex / Elite Force

"Amazing pistol, full auto is lite, it stoped shooting I think the battery’s fried but that’s not the guns fault

"So I bought this because I just did??? It might be a little underpowered but it’s not a primary weapon so I’m not interested in a need for long distance accuracy. I bought two extra magazines simple because it will fire full auto. Oh such fun. I have not worked out how to attach a suppressor/tracer to it yet, any suggestions welcomed.
Pros
No gas to mess with
Fun
Cheap magazines
Solid construction
Going to buy a second one!!!

Cons
Took forever to work out where the battery went.
I hope I won’t loose the mags as they are so thin, but solid.
Can’t work out how to attach tracer suppressor

Really is a fun alternative
Not sure how long the battery is going to last may or may not need a second one.

"My brother got this in a box-of-awesomeness, and sold it to me. It's actually pretty nice.

TL;DR:
Overall, a good buy IF you're inclined to tech on your gun.
If you're looking for the fun/realism of blowback, then you should pass on AEPs.



First thing about AEPs: they're not great out of the box. If you like to tinker, and live where it's too hot for CO2, then this is the gun for you. (or if you hate having consumables like gas)

Look on youtube for some battery guides; these get WAY better if you buy a little LiPo battery and stuff it in there. If you get an 11.1V, you'll also need a MOSFET. I recommend a Perun AB; it'll barely fit under the slide, provide active braking, and save your poor trigger contacts. On full auto, it also improved the fire rate by ~5rps; not trivial.

The pistol itself is solid. Nice weight, and the mags are CHEAP. Like, $10 each.

Pros:
Works in all temperatures.
No consumables (gas, etc).
No mag sealing issues.
Semi/full auto selectable.
Proper trademarks (EF/Umarex version)

Cons:
Weak (maybe 200fps if you're lucky on 0.25g bbs).
Slow, unless you upgrade batteries.
Needs mods to become a beast.
No blowback realism.

With some upgrades (drone racing LiPos, MOSFET) and a little elbow grease, it'll sing like Pavarotti...
And get you a head-nod from other techs on the field, if you care about that sort of thing.
