SIG Sauer MPX VS HK MP5

The SIG MPX is a gas-operated submachine gun designed and manufactured by SIG Sauer, and is primarily chambered in 9×19mm Parabellum cartridge. It is a gas-operated firearm featuring a closed, rotating bolt.[1] These design features, rare in submachine guns, were chosen to enhance the safety of the user and to have a more reliable firearm. It was designed in 2013 and was released to the general public in 2015. It features the SIG Sauer short stroke push-rod gas system to reduce the recoil and improve the reliability of the weapon. The MPX, in its second generation, features a system that would allow for conversion from 9mm to .357 SIG or .40 S&W. However, since its inception, first party conversion kits have not been made available for either of the two production generations of the gun.

This is the first official Heckler & Koch MP5-SD chambered in .22 LR. Authentic in looks, feel, and operation, this replica MP5-SD is engineered as a dedicated .22 rimfire rifle. It's built in Germany 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 compensator is attached so that the 16.1 inch barrel extends the full length of the gun and compensator. On this page we've curated the biggest list of MP5's for sale from the top online dealers.
