Excel Accelerator Pistol MP-5.7 5.7x28mm 8.50" 9+1 Black Stainless Steel Black Polymer Grip (BOX INCLUDED) The Excel Arms Accelerator Pistol MP-5.7 is a purpose-built, American-made handgun engineered around the speed and flat-shooting characteristics of the 5.7x28mm cartridge. Its stainless steel bull barrel delivers rigidity, heat stability, and consistent point of impact, while the integrated aluminum top rib provides a solid Weaver-style mounting platform for optics. The heavy stainless steel frame tames recoil and keeps the pistol planted, giving shooters a stable, predictable firing cycle. Adjustable target sights, a manual safety, and a hammer-fired double-action system round out a design focused on control, precision, and durability.
