The Heckler & Koch MP5 has been the CQB weapon of choice for military and government operatives around the world for better part of the last half century. Weighing in at just over five and a half pounds this 9mm select fire submachine gun gained popularity for being lightweight and easy to maneuver. There have been over 120 different variants of the MP5 each addressing specific tactical requirements making the gun extremely versatile.
This airsoft replica of the MP5 is fully licensed with H&K trademarks through Umarex. It is manufactured under contract by Top Tech of Taiwan and uses their own Pneumatic Blow Back gearbox. Unlike other AEG blow backs which use a tow hook design where the bolt is physically pulled back by the piston, the Top Tech pneumatic system incorporates a secondary cylinder on top of the gearbox which uses a very small amount of air compressed from the main piston to drive back the bolt. Since the system operates solely on air pressure it does not put any stress on your gearbox and does not affect its rate of fire. Also, unlike most tow hook systems the bolt will only recoil when the gun fires making it much more realistic. When the system operates it emits a series of metallic sounds which combined with the noise of the air expanding the secondary cylinder gives this gun an intimidating report.
Top Tech is partnered with G&G and have used their rugged EGM body for their creation. This two piece metal body quickly separates after simply removing a single pin from the receiver making them very easy to take down for maintenance or modification. They used a Version 2 gearbox which although modified for their pneumatic system is still compatible with most aftermarket upgrade parts. Although out of the box this gun is already pretty well equipped with steel gears running on 8mm bearing bushings, a steel core spring guide with bearing, a ported aluminum piston head with bearing and low resistance wiring.
The H&K MP5-SD5 configuration features an integral mock suppressor, a full stock and ambidextrous selector switches along with authentic HK style rotary rear sight and hooded front sight. Its stock is spacious enough to house large type batteries up to a 9.6v 4500mah. However, for reliability reasons we do not recommend using a battery this large as it can push the guns rate of fire to damaging levels. Using only an 8.4v battery this gun will produce a withering 1,000 rounds per minute which will put 16 rounds in the air in less than one second. This coupled with a healthy muzzle velocity of 350 fps makes this an ideal gun for both indoor and outdoor fields of play.
Putting together the sheer shooting enjoyment of the pneumatic blow back, the awesome build quality and design, plus the fact that this is one of the first quality MP5 AEGs to be licensed by H&K makes this a must have for the collector and shooter alike.
: Since the pneumatic blow back operates on back pressure from the piston, the bolt will only recoil fully when the gun is loaded.
