Heckler & Koch is world renown for reliability and making sexy guns.  Heckler & Koch (H&K), in English is pronounced Heckler & "Coke".  Now with that out of the way H&K is a German military defense manufacturer.  What is a defense manufacturer? They specialize in making Militär waffen or military weapons. Their company motto is currently Keine Kompromisse! (No Compromise!) and depending on the era you may also know that their catch phrase used to be "In a world of compromise, some don't." Now lets talk about some of the other iconic offerings from H&K you may be familiar with such as the G3, MP5, MP7, MK23, HK69, G11, HK 21, P7, VP70, USP and the list goes on but those were my personal favorites. Today we will be looking specifically at the UMP 45 which was produced in the 90's and was designed to be a lighter and more cost effective alternative to the MP5 which is still in production and has been since the 1960's.  The real UMP is offered in a few different flavors such as 9x19mm, .40 S&W and .45ACP.  The UMP has been a favorite of mine since 1998 when I used to play the computer game, Tom Clancy's Rainbow 6.  Enough history. 

Elite Force Airsoft is a division of Umarex, which is a Airgun & sporting goods conglomerate from Germany. Elite Force Airsoft division focuses on the Airsoft side of their business and is responsible for providing excellent products and customer service. Elite Force Airsoft (and Umarex for that matter) specialize in offering licensed replica airsoft guns and hold some of the best names in the real gun market and thus can offer us some amazingly detailed licensed Airsoft replicas. With that being said we have the H&K UMP 45 Gas Blow Back Rifle (GBBR)

The H&K UMP 45 GBBR is a high end, Taiwan made, green gas powered airsoft gun.  The body construction is polymer just like the real one and would still be considered a "metal body gun" in airsoft terminology.  The polymer used is extremely impressive and feels much like a real USC (That is not a typo, the USC is the civilian version of the UMP.)  I am not cool enough to have fondled or shot a UMP, just the USC variant.

The first thing that really stands out to me is the magazine, THIS THING IS HUGE! <insert witty remark here> Why is it so big you ask (don't even say it)?  Because the real one is meant to hold 25 rounds of .45 AUTO, and to do that effectively and not be a foot and a half long single stack magazine it is a girthy 25 round, double stack magazine.  However for airsoft purposes this bad boy holds what seems like an entire can of green gas and 30 rounds of 6mm BBs.  Oh and the magazine doesn't really hold an entire can, it just holds A LOT of gas, which is a good thing. I'd much rather run out of BBs before gas as with some select fire airsoft sub machine guns.  You may also be wondering what all this writing on the side of the magazine means?  Well it all happened on a dreary September day in 1994 when former President Bill Clinton (domestic partner of Hillary Clinton) signed into law the "Violent Crime Control and Law Enforcement Act of 1994." Which enacted the Federal Assault Weapon Ban which specifically banned many SEMI-automatic weapons which had a detachable magazine and 2 or more features or characteristics of an assault weapon (Who gets to consider what features make a sporting pistol, rifle, or shotgun an evil assault weapon when the weapon has never assaulted anyone is beyond me.)  Besides banning a number of types of guns the law also banned possession of newly manufactured magazines holding more than ten rounds of ammunition and all magazines manufactured during this period had to be stamped "Restricted Law Enforcement / Government Use Only" and have the date stamped on the magazine. Fast forward 10 years later and the Assault Weapon Ban sunset September 2004 and is no longer in effect. Studies have shown no statistically significant evidence that either the assault weapons ban or the ban on magazines holding more than 10 rounds had reduced gun violence.  

The next thing that really pops out at me is the side folding, skeletonized stock. H&K guns always have the coolest stocks in my opinion and this one is certainly no different.  The stock has the perfect length of pull for use with or without body armor and when deployed provides a really stable platform and is really robust.  Everything about it screams German engineering from the well thought out stock holes (what about the holes?? more on that next) to the intuitive stock release button, latch and hinge mechanism. 

Tada!  It's to hold you pins while field stripping and cleaning your gun.  It is a very well thought out design feature which they have been implementing since the late 1950's.  Could you imagine being in a active war zone in some outpost and you need to clean your rifle because you decided to fall into a big mud puddle and while cleaning your disassembled rifle, Murphy decided to make your pin go full Chuck Norris on you and end up missing in action. I suppose the pins could some how be captured like an M16 or retained some how, but probably due to the construction design that would not be feasible and a push pin would be the only option. I actually really wish Airsofters would use this feature, especially on the G36 and MP5A4 while changing their batteries.  

While we have the thing cracked open, lets look at the internals of this gun.  Here you can see the trigger pack, and internal guts as well as the ball bearing roller hammer.  Much like the real gun, its simplicity makes it beautiful. 

Besides the trigger pack in the previous picture, this is the only other moving, mechanical part in the gun. The bolt houses the loading nozzle and all the gas blowback related parts.  Take a look at the burly recoil spring.

The recoil system is well thought out and the recoil spring is as it should be. But, looking further to the left, we see a polymer recoil buffer which the bolt directly impacts (this reminds me of the recoil buffer used in the real USP Compact).  The shock mitigation doesn't end at the buffer, note the burly spring just to the left of the buffer, that is a burlier spring which absorbs any excess rearward movement of the bolt and protects the entire body of the gun, especially the lower receiver from stress fractures overtime. It also sends that bolt home with authority for a very satisfying felt recoil and sound.


The gun is awesome and can be field stripped into 3 basic components, talk about not a lot of moving parts, this should be a very easily serviceable gun in the future.

While we are still looking at the aft end of the gun, lets look at the rear integrated sling loop and that burly stock latch we mentioned earlier. This mounting point would be perfect for mounting a Lancer Tactical Single Point Bungee Sling.

The rear sight is fully adjustable for elevation and does not require any absurd tools like the MP5 or G3 and features two apertures, a ghost ring, and a notch sight.  I do prefer a ghost ring sight, however I feel for the close in use and with having a electronic dot sight mounted co-witness to the irons, I prefer to use the notch rear aperture as it allows looking through the dot sight at unconventional cheek welds and takes advantage of the "parallax free" theory of red dot sights.

In the above picture you can see Lancer Tactical Mini Red/Green Dot Sight co-witnessed nicely with the irons. You may start to notice a trend of me using this particular sight, but it is my favorite sight, it is just so versatile and works great on so many applications.

Here is a better view of the Lancer Tactical Mini Red/Green Dot Sight, it's so unobtrusive and at home on the UMP.

Next to SEF this is quite possibly the most iconic and recognizable selector markings of all time, BULLET PICTOGRAMS!  H&K on their MP5 Navy lowers used pictograms to show you what the different selector positions would do.  In the above picture you will note 4 different pictures.  This lower has Safe, Semi, 2 round Burst and Full Auto. The gun actually has a fully functional 2 round burst! I think this is just too cool, especially with a Gas Blow Back Airsoft Gun with limited BBs and gas.  You can conserve ammo but get higher hit / calling hit probability by automatically double tapping people for you.

Another familiar feature for those old school HK users, a paddle magazine release!  You can love and hate the paddle magazine release. It is very intuitive and positive, however it is just a hair slower on reloads versus drop free magazine designs with a button you can press with your strong side index finger.

While we discussing notable H&K features, lets look at the forward cocking knob, an iconic sight of H&K guns.  It is also a favorite of Airsofters who love to do the "HK Slap" over and over until their cocking knob breaks off and flies forward. Now days it doesn't seem to be an issue but certainly was with old school Tokyo Marui MP5 variants.  Luckily this is a gas blowback and this is how you cock the gun, so it is certainly not decorative, so start slapping away and look like a boss on your next reload.  Ooo, look at that sexy sight again.

Moving forward there are two notable features we should look at in this picture, lets look at the front ambidextrous sling loop which are perfect for the H&K 3 Point sling with HK Hooks.  Next lets look at the bright orange muzzle device, much like MP5s, they used a special base mount, which you could then quickly attach your desired muzzle device, such as a Navy Flash Hider, or suppressor.  It appears they use a ring now opposed to the HK 3 Prong Muzzle, however the concept is very similar except the bearings surface is pretty much 360 degrees.

In this picture you can see the muzzle device I referenced above but more notably you can check out the rail interface system on the front of the gun as well as one of my favorite vertical fore grips, the ASG Hera Arms HFG.  It is such a nice looking design and so comfortable. It looks great on just about any gun with its modern styling.

I love using the Action Sport Games weapon light as it is low profile and short in overall length, perfect for shorter guns. On M4 variants I like to use a SureFire Scout light, but being 6V and the batteries in a line, it makes the overall length of the light very cumbersome.  The ASG Weapon light is still 6V meaning it has 2 CR123A batteries but is short in overall length and has built in paddles to turn the light on and off, which are in a perfect position for manipulation with your thumb while using a vertical grip.

Overall, if you are an H&K Enthusiast/Collector or an airsoft player that loves gas blowback rifles, look no further and definitely consider the Elite Force H&K UMP 45 GBBR! The recoil and cyclic rate is stout and satisfying and is shooting at a respectable 380FPS with a .20g BB in my testing.  Click here to check out more on the Elite Force UMP 45 at Fox Airsoft.
