Our take:  Heckler & Koch, renowned for manufacturing industry leading real steel firearms, has released a fully licensed Sportline AEG version of their modern UMP45 submachine gun, featuring a lightweight compact design and premium internal components.  This NEW and fully licensed CQB AEG features a rock solid polymer body, similar to the real steel H&K UMP45,  and plenty of rail space for attaching modular weapon accessories.

The UMP was designed as a lighter weight alternative to the H&K MP5 submachine gun, and is currently being used by military and law enforcement agencies world wide.  Inside the rugged polymer body is a unique and innovative full metal Version 3 gearbox, featuring a quick change spring option and an improved electric trigger switch, providing lightning fast trigger response and improved versatility. This HK UMP45 AEG, manufactured by S&T, shares many of the same internal components and performance features with the premium ARES/ STAR UMP45 AEG, at a fraction of the price!  The NEW HK UMP Submachine Gun AEG's rugged construction, premium performance,  innovative internal design, and affordable price tag truly sets it apart from other compact SMG AEGs on the market!

Battle Ready Exterior:
The HK UMP45 AEG features an impact resistant polymer body, built to withstand even the most intense simulated airsoft combat conditions while keeping the AEG's weight to a minimum.  Unlike most inexpensive compact CQB AEGs on the market, this NEW HK UMP45 AEG features fully licensed trademarks which are prominently displayed on the lower receiver.  The solid construction of the HK UMP45 AEG polymer body, paired with fully licensed trademarks from Umarex gives this CQB AEG a truly authentic look and feel.  Another great feature of this HK UMP45 AEG is the attached accessory and optics rails, which provide plenty of rail space for attaching modular accessories and optics.  The bottom, left, and right accessory rails are made from full metal, creating a more stable platform for accessories.  The top optics rail is made from ABS plastic, however its design makes it very rigid and easily capable of carrying heavier optics accessories.

The UMP45 is known for its ease of use in close quarters environments, thanks to its side folding stock, allowing you to easily corner in close quarters combat.  The HK UMP45 AEG also features front and rear sling mounts, as well as an ambidextrous selector switch.  Field stripping the HK UMP45 AEG is incredibly easy, allowing you to quickly access the gearbox and hop up for repairs or adjustments.  With a rugged and light weight build, compact size,  modular capabilities, and fully licensed Heckler & Koch trademarks, the NEW HK UMP45 AEG, by S&T, is sure to be one of the most sought after compact submachine gun AEGs on the market!

Innovative Gearbox Design:
S&T has truly created one of the most versatile full metal Version 3 gearboxes on the market, with an integrated quick change spring design, as well as upgraded and reinforced internal components.  The quick change spring option allows the player to easily swap out different power AEG springs, all without ever removing the gearbox!  This is a great feature for players who want to use one AEG for both indoor CQB and outdoor field settings.  Simply open the door at the rear of the AEG and put in whichever spring provides you with "field legal" FPS!  Another great internal feature of the HK UMP45 AEG is the electronic trigger switch, which provides faster trigger response and eliminates the risk of wearing down trigger contacts.  The only other UMP AEG with similar internal features costs over $100 more! Don't miss out on one of the most adaptive and effective UMP45 AEGs on the market!

If you are looking for a mission adaptable AEG, with a rugged and authentic exterior, paired with high performance internals then the fully licensed HK UMP45 AEG, manufactured by S&T, is the AEG for you!

Features:
- Adjustable hop-up unit
- Adjustable rear sight
- Full length top rail
- Functional charging handle
- Quick Change Spring Option
- Fully Licensed Heckler & Koch trademarks, licensed by Umarex
- Easy field stripping/ disassembly
- Easy access battery compartment

Package contents:  HK UMP AEG, Hi-cap Magazine (400rd), 8.4v Stick Type Battery, Standard Wall Charger, Manual

Battery Charger Recommendation: Airsoft Megastore recommends the use of a smart charger to avoid overcharging the battery (overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly).  Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly, also automatically shut off once the battery is fully charged to avoid overcharged batteries.

5 HK Licensed Airsoft UMP 45 Full Metal Gearbox AEG CQB Submachine Gun *****
perfect gun

"ive had a couple aeg's and this is by far my favorite. it has an insane rate of fire for a 8.4 volt. pros: great, compact fast rate of fire, light weight, very durable. cons: the charging handle doesn't work, and the trigger pull is to long. Other than that its a great gun. like an amazing gun. i recommend this gun to any intermediate or expert player. easy to upgrade and comfortable."

absolutely worth every penny

"so my friend bought this gun on a whim, i borrowed it for two weeks and fell in love, so i bought one myself. i have seven guns of dif types and name brands, nothing crappy. some fell apart, some work quite well. this has been my most reliable. not one hiccup for any reason in over a year. super easy to work on, pulls apart with one pin (not that u need too but if u want too) and it has a quick change spring, super ergonomic, surprisingly accurate, light, durable, small and easy to maneuver. best cqb gun ive ever used by far!!!!! its become my go to gun above all else. i even use it outside in the open areas a lot. the fps is definitely meant for cqb and is kind of low, but it still reaches fairly far. also you can easily unscrew and remove the whole fake cocking handle assembly (it doesnt move anyway) and the top of the gun is totally hollow ( put the front cap back in though) and fits the matrix 9.6v 2200mah 4/5a large type stick battery that comes w a small tamia, which makes it fire much faster and lasts forever. the version 3 gearbox feels soo solid and is quiet, and almost never locks up in semi, v2 gearboxes are terrible for that. bang for your buck NOTHING will beat this. if you wanna buy more expensive, fine, but on a budget nothing compares and even next to expensive stuff its pretty awesome, my friend and i love this thing and both definitely recommend it to anyone, new or experienced... oh and im 27 years old not 10, just sayin."

UMP 45 AEG (EF)

"First hand, it is a very good piece of equipment. I do believe that this is a 1:1 replica. It is light-weight, sturdy, versatile and strong overall; has a magazine with a healthy 400 rounds for extra carnage. Even comes with a battery and a charger for your convenience. Comes with rails on the sides, top, and bottom for optics, lasers, and fore-grips. There are two things that I was disappointing about though. One (1) is the non-functioning charging/cocking handle. I was really looking forward for the 'HK slap'. It kills sometime when you're bored >:D. Second (2) is the fact that there are no threading on the barrel. Without the threading, one cannot attach a silencer or any other barrel extension. Other than that, I cannot complain. I have no regrets of purchasing this equipment; recommend to anyone new or pro. Good Hunting!"

pretty good

"i love the gun. I've had it for about one year and it works fantastically. the trigger pull is long but isn't a bid deal when you get used to it and it can fit a 9.6 volt battery. the only thing that i found annoying is that my mag wont feed sometimes but is fixable. other than that it would be 5 stars. i recommend this gun for any player. thanks for taking the time to read this."

Pretty Good

"First off my gun would not fire when i first got it, it dry fired only. Turns out that the mags had to be broken in so do that. On to pros and cons: Pros: Great rate of fire, good range for a cqb gun, ok acuracy at close range, and nice and light. Cons: acuracy is bad at distance it looks like a shotgun at one hundred feet, low fps, and thats it. Upgrades: 400 fps spring, 2 more mags because if you use the best quality on the gun, high rof, you blow through mags, angled and vertical; vertical for attaching laser and light preasure pads, angled for the outdoor field., laser , light, EOtech, point sling, and get .2 bbs they work the best, Thanks for reading"

Pretty great gun

"When the gun came out of the box it wasn't too bad from the moment I pulled it out it was awesome feels really nice the plastic isn't isn't cheap plastic so when you hold it's got a nice feel to it, the stock can be just a little awkward since is not adjustable and only foldable so if you're used to the adjustable M4 stock then it's going to take some time to adjust. As far as the battery goes when I finally did charge it and put it to shoot it only shot for about 10 maybe 15 minutes so I recommend getting a new battery for it, as far as the railing goes I don't have a problem putting my fore grip on it and I haven't had a problem with the sling getting in the way, the fire rate is pretty good to start off with and I did have the same problem as other users where the mag doesn't want to feed into the gun properly. I haven't checked to see if mock suppressor can be added to it but I'm assuming it can. All in all this gun is great and if you're looking to just start, or adding to your collection, then this is definitely one that you want. "

ump 45

"I have to say this gun is very good for its price. It comes with a high cap, battery, and charger. (I would recommend a smart charger) Pros: good rate of fire very customizable for any optics comes with every thing you need to start airsoft metal gearbox Cons: Mags some times don't feed well But besides that it is a good gun for a good price!"

All around good gun

"I bought this gun mainly for CQB confrontations but often found myself getting kill shots from medium and occasionally long range encounters. I ended up buying a 4x magnification ACOG for it because it was so accurate. It was great at CQB as we'll due to the folding stock. The only problems I had were that sometimes the mag has trouble feeding into the gun (just hold it in with you hand for a couple shots and that will fix it) and that occasionally the button to fold the stock jams in and won't pop back out (just pat the stock a few times and it comes back out). All around, this is an accurate and reliable weapon to dominate the battlefield at all ranges. PROS -accurate -good FPS -high rate of fire -plenty if rails for customization -relatively cheap CONS -mags don't feed at times -mags are awkward and bulky (after all it is a .45 in real life) -charging handle doesn't function - button to fold stock jams in"

UMP 45

"First off the mag is bigger than expected, tried to use the gun and the battery gave out after ten minutes. I do have a smart charger and I am going for round two in an hour. It shot great but needed a lot of winding of the mag, probably am going to get some med caps for this gun. I did not feel a long trigger pull like other people who bought this gun, but I also did not shoot it for long to tell. It is plastic but it's not a cheap plastic. Don't throw it around or anything cause it will break."

Ok gun

"This gun is overall ok. I bought it about 6 months ago, and a couple of things have gone wrong. The air nozzle has somehow gotten chipped, and the tappit plate broke. But those are easy fixes. Pros: lightweight, small with folded stock(enough to use with my sniper), fast rate of fire, realistic charging handle Cons: only takes stick type batteries(i modified mine to take other types), in order to put a foregrip on you have to remove the bottom rail due to the sling mount, crappy sling, battery that came with it was horrible. Metal rails could be pro or con, becaues they eat away at any plastic foregrip. Most 9.6 v batteries i have tried are too long to fit in the compartment, as it is very specifically sized. Overall i would buy this, just make sure you get another stick battery."

Nice Sportline Gun

"I just got this gun today but have been shooting it around outside. I bought a 9.6V battery along with this and it greatly increase the ROF. I originally encountered problems with the magazine not feeding BBs, but after awhile it fed them better. I attribute this to the magazine needing to be broken in first. At first I thought there was something wrong with my gun because I pulled the trigger back and nothing happened. It turns out that this gun has a longer trigger pull than the guns I have fired. Onto Pros & Cons. Pros: Lightweight Lots of Rail Space Large Magazine Capacity Quick Change Spring option High ROF (with 9.6V at least) Built in iron sights (with two different options for the rear sight) Cons: You can see where the plastic body was attached to the mold (kind of cheap feel) Long Trigger Pull Can't put a slide on vertical grip on the bottom rail due to the sling mount. The Stock doesn't like to come unlatched sometimes Cramped Battery compartment with 9.6V stick battery (not to bad though) The barrel isn't threaded for new flashiders/mock suppressors (as far as I know)"

Awesome!

"I just got this yesterday for Christmas, and I'll have to say as my first (working) Airsoft gun I really enjoy it. It came complete except for one part, it did not come with a lazer. Its light-weight, sturdy, hard-plastic, and very fun to use. The only thing that really bothered me was that the safety doesn't work, it fires even when on safety. PROS:Hard-plastic, light-weight, accurate, folding stock, and it comes with a high-cap mag. CONS: Didn't come with a lazer, my safety came broken, and the trigger takes to long to fire a bb."

Meh

"This gun was great... when I first got it. It was working perfectly for a while, but then the battery died mid shot, and messed up the gun. It doesn't fire anymore. I might buy another one of these when I get the money, because I like UMPs, and this gun is perfect for me. When you buy this gun, be careful about the battery life and stuff."

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
