Mi Shotgun Stock Mossberg 590 Blk$274.95
Availability: In Stock
If you run a Mossberg 500 or 590 shotgun and want the ergonomic flexibility of AR-platform controls, the TacStar Industries AR Stock Adapter bridges that gap. This die-cast metal adapter lets you mount standard AR-15 telescoping stocks and compatible pistol grips to your shotgun receiver, giving you modularity that factory shotgun furniture can't match. Built from tough metal alloy rather than polymer, it adds structural rigidity and a bit of weight—both desirable traits when you're managing shotgun recoil.
The adapter is engineered to sit flush with Mossberg receiver contours and maintains proper sight picture alignment for bead or ghost ring sights right out of the box. It accepts most AR-15 grips without a beavertail, or those with flexible rubber beavertails like Pachmayr, Ergo, and some Hogue models. You'll also get QD sling attachment points on both sides, so mounting a single- or two-point rig is straightforward.
Installation is uncomplicated—no gunsmithing required. The adapter simply replaces your factory stock assembly and accepts industry-standard AR components, opening up dozens of aftermarket stock options. Whether you're building a home-defense shotgun with tactical ergonomics or a sport-clays gun with a modern handling profile, this adapter makes it happen without replacing the receiver itself.
