What’s Included
- Excel Arms Accelerator MP-22 pistol
- One factory 10-round stainless steel magazine
The 8.5-inch bull barrel, machined from 17-4 PH stainless steel, delivers higher velocities than shorter rimfire handguns while adding rigidity for consistent accuracy. Its stainless finish pairs with a black polymer frame for a durable two-tone look.
An integral full-length Picatinny rail runs the top of the receiver, giving you immediate mounting options for optics without additional hardware. Forward-angled rear slide serrations and a reversible cylindrical charging handle provide ambidextrous, glove-friendly manipulation.
The pistol operates on a simple blowback action and uses an internal hammer with a single-action, wide stainless trigger. Safety features include a manual thumb safety and a firing-pin block for confident carry and bench use.
Fully adjustable rear sights work in concert with the ramped front post for precise elevation and windage correction when shooting .22 WMR loads at varying distances.
