The Walther H&K MP5 SD rifle looks, feel,and operation was to my highest satisfactions. This is a replica HK MP5SD chambered .22 Long Rifle, and is built with a match grade precision barrel, metal receiver, and retractable stock. 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 was very easy to load thanks to the dual grip that was made for holding the spring while loading. It is made from high-strength polymer, and comes in 25- and 10-round versions of the magazine.
The .22 caliber Walther HK MP5 SD operates off of a blowback system. After the magazine is empties the bolt will remain open. The front sight is adjustable for elevation and comes with interchangeable posts. The rear sight is also adjustable for windage and elevation.
On the range
When we got to the range, I was like a little girl that was told she was getting a pony for her birthday! The Walther HK MP5 SD was so easy to use and a pleasure to shoot. The recoil on the gun minimal, also it was light weight so that made it easy to shoot from the standing position. I cant wait to take it back out to the range!
