Heckler & Koch addressed the unique needs of special forces units by developing the silenced MP5SD. Despite incorporating a built-in silencer, this variant maintains the identical length and shape of its unsilenced counterpart. Unlike many traditional silenced submachine guns, it utilizes standard ammunition without requiring special subsonic rounds, while still delivering the same impact. The integrated silencer significantly suppresses muzzle flash, making the weapon highly suitable for night operations with low-light amplifiers. Consequently, the MP5SD stands out as one of the most precise silenced submachine guns in its category.

The Hitec Arms SD Barreled Receiver Optic Ready with Top Rail is a 9mm semi-auto roller lock pistol meticulously crafted by HTA. It includes a full auto bolt and bolt carrier, making it an ideal choice for your 922 R compliant short-barreled rifle project or as a host gun for your full auto sear pack. The unit transfers as a receiver, eliminating the need for any specialized NFA paperwork. Once you take possession of the barreled receiver, you have the flexibility to add your preferred trigger pack and suppressor. Each gun is meticulously hand-built with attention to detail and undergoes a comprehensive 31-point quality check, including firing 30 rounds of ammunition before final approval. We stand behind the quality of the parts and construction, offering a confident HTA 5-year factory warranty.

The receiver flats undergo precise rolling, ensuring accurate welds that are both aesthetically pleasing and structurally sound. The front sights are meticulously pressed on and pinned, mirroring the original German build process, as opposed to being welded like in some other cases. Throughout the construction, rigorous headspace checks are conducted at various stages to maintain tight build specifications from start to finish. The gun boasts an exceptional finish, featuring a base of Parkerization coupled with a final coat of Durakote paint that is nearly indestructible. This exclusive finish covers the entire firearm, both internally and externally, with a consistently impressive thickness of .003, showcasing a level of beauty that rivals certain custom high-end guns.
