The new GSG-5 .22 caliber semi-auto rifle from American Tactical Imports is an exact replica of the H&K MP5 sub-machine gun aside from the caliber. Ergonomics and handling are identical to that of the MP5 with an overall length of 33.5 inches and a weight of 6.6 pounds which makes it an ideal training tool for Law Enforcement, Military personnel or civilians. 22 long rifle offers an immense savings over 9mm/40/45 caliber ammunition allowing extensive range time with the GSG-5 at a minimal cost to the user.

Barrel length on the GSG-5 rifle is 16.25 inches including the faux suppressor, which surpasses federal requirements making it legal to own by anyone. The GSG-5 utilizes either a 22 or 10 rd detachable box magazine that releases with an H&K style paddle magazine release. The charging handle on the GSG-5 is located on the left side of the receiver and is non-reciprocating just like the H&K MP5 series.

The GSG-5 comes standard with a conventional MP 5 style stock and fore end but American Tactical Imports also offers several different style stocks and tactical fore ends, including a side-folding stock like the H&K MP5k-PDW, and a retractable stock as offered on the H&K MP5A3. The GSG-5 comes with a standard H&K style fore end but is upgradeable to a tactical railed fore end that accepts tactical grips, lights and lasers.

The GSG-5 utilizes the H&K style Drum sight that is windage and elevation adjustable. Accessories available for the GSG-5 include a claw mount with picatinny rail allowing just about any optic from a tactical or hunting scope to a Close Quarters Battle optic like a red dot sight to be mounted on the receiver. In addition to extra magazines ATI also offers a tactical magazine coupler for joining 2 magazines together making for a faster reload. American Tactical Imports also offers an MP5SD style barrel/faux suppressor that looks exactly like the original. Whether you are looking for a low cost tactical trainer or a fun plinker the GSG-5 rifle is a winning choice.
