Umarex H&K G36K

Umarex brings us a G36K manufactured by ARES with an unusual stock, a low rail with RIS and folding sights, a slim handguard that combines RIS, Keymod and HKey mounting slots.  Since HK created this well-known model in the 90s for the German Army, many other countries’ armies and elite police units have adopted different variants of this assault rifle.  And in airsoft, this Umarex replica gun shows why the G36 is so popular, specially with all the specs it has to offer!

Licenses

Umarex has the licenses of Heckler & Koch which means that you can enjoy a replica truly similar to the real model, which obviously includes showing the real markings of the original G36. A point of added value that although it does not affect the game, many airsofters appreciate due to the extra realism they bring.

Handguard

The model has a handguard longer than that of the K (Kurz) or C (Compact) models. A design made of CNC aluminium, thinner than the conventional polymer, which has Picatinny rails both in its lower and upper part, and on the sides it is replaced by a Keymod line and the HKey mounting slots of the German manufacturer. Although you won’t notice it with the grenade launcher’s configuration, if you use it without it, the grip is more comfortable, closer to what you are used to in the M4 type tactical carbines.

Stock

Although the design of the stock is different from the standard, it is a real stock taken from the HK catalogue, which is still foldable but provides more advantages. The first is that you can adjust its length in up to four positions, you can also adjust the rubber recoil pad so that your eyes are at the height of the sights or higher if you use a scope. And if you are wondering what are the stock holes for, they are for storing the pins that will allow us to disassemble the model, 

an intelligent solution by HK. When you have to disassemble the replica in the middle of the field you will thank the system for not losing the pins, it already saved our lives.

Internal Parts

Characteristics:

V3 EFCS Gearbox with Blowback 
Blow Back System
Quick spring change
120 spring type
Metal hop-up chamber
500 mm internal precision barrel
Programmable EFCS electronic trigger
Hi torque motor

It has an ARES EFCS version 3 gearbox with quick spring change 1 by removing a pin to disassemble the piece that will give us access to the spring guide without even having to disassemble the replica. The spring guide 2 is made of steel and does not include bearings, and the spring 3 is an M120 type. When opened completely, you find some steel gears 4 that rotate on two bushings 5 and a bearing 6, a configuration we have already seen in other models and that achieves great performance. 

The pneumatic set has polymer piston7 with a metal toothing 8 and a piston head 9 also made of polymer and without bearings. The cylinder 10 is chromed, lacking an opening, and together with the cylinder head11 and the polymer nozzle 12 provide a great seal for the set. The 6.04 mm precision barrel 13 is 500 mm in length, and works very well with the TM type polymer hop-up chamber 14 and the ARES rubber, posting an average of 385 FPS in our tests (please note this may vary depending on the market to which the replica is intended for) and a firing rate of 850 BBs per minute.

The electronic EFCS trigger 15 (Electronic Firing Control System) offers a smooth and fast firing response, although you can also adjust the hair or the distance the trigger has to travel to shoot. You can program the firing modes of the fire selector but it already has all four positions (safe, semi, burst, auto). 

The EFCS has a low-voltage battery detector that stops firing the replica when it reaches a minimum, without danger of discharging the battery too much or damaging the gearbox, and without the annoying beep of other replicas. It offers a low consumption motor start, in addition to supporting higher firing currents (up to 30A) and has a magnetic neodymium sensor for proper piston positioning after each shot. A detail that helps the correct functioning of the gearbox and prevents malfunctions.

Conclusion

HK will always be a fetish brand within the world of airsoft, and the G36 is its flagship for many players looking to get break away from the M4/AK dichotomy. But when you bring together both the realism that Umarex brings with official licenses and the robustness in the construction ARES is known for, you find a more than interesting set, both for CQB (with the folding stock and grenade launcher) as for open field (thanks to the length of the barrel and how light it feels).
