The H&K MP5 SD offered by Umarex USA is a rimfire rifle authentic in looks, feel, and operation. This HK clone is engineered as a dedicated .22 Long Rifle. It’s built with a match grade precision barrel, metal receiver, and retractable stock. It also has a NAVY pistol grip as well as HK MP5-style sights. The sound dampener (SD) is actually a compensator. It is attached to conceal the 16.1 inch barrel that extends the full length of the gun and compensator.
The MP5’s magazine is made of high-strength polymer and is designed for ease of loading with dual grips for holding the spring when loading. A 25- and 10-round version of the magazine is available. Both are proportionate in size to the centerfire version’s mag to maintain the authentic look of the 9mm MP5s magazine.
A blowback system operates the .22 caliber HK MP5 SD. When the magazine empties the bolt remains open. Its front sight is adjustable for elevation and comes with interchangeable posts. The rear sight is adjustable for windage and elevation. The safety switch rotates 90 degrees, as does the 9 mm MP5.
