The Aim Sports APGSM500 Shotgun 6 Position W/ Pistol Grip Black Synthetic For Mossberg 500 is a complete stock and grip upgrade for popular Mossberg 12 gauge pump models. This kit pairs an ergonomic pistol grip with an M4‑style, 6‑position collapsible stock, giving shooters a more natural hand position, improved control, and an adjustable length of pull. The polymer grip includes internal storage and an ambidextrous sling loop, while the stock rides on a durable aluminum buffer tube for repeatable, wobble‑free adjustment.

Designed as a true drop‑in replacement, this Aim Sports setup installs in minutes and immediately modernizes the feel of your Mossberg 500, 500A, 535, 590, 835, or Maverick 88. It is well suited for range use, training, and general defensive roles where a compact, easily shouldered shotgun is preferred. The combination of lightweight synthetic construction and thoughtful ergonomics reflects Aim Sports’ focus on practical design and dependable performance.
