TacStar Stock Adapter Mil-Spec AR-15 for Remington 870 12GA

The TacStar Stock Adapter is a drop-on ABS polymer interface that lets a Remington 870 12 Gauge shotgun wear modern Mil-Spec AR-15 furniture. Once installed in place of the factory stock, the adapter accepts any telescoping AR-15 carbine stock or AR-15 pistol grip, opening up the entire world of aftermarket AR furniture for the venerable 870.

The adapter is designed to fit standard AR-15 grips without a beavertail, as well as grips fitted with a flexible rubber beavertail from makers such as Pachmayr, Ergo, and many Hogue patterns. At a compact 7.7" overall length, the unit installs in minutes with no gunsmithing required, making it one of the simplest ways to modernize the ergonomics and adjustable length-of-pull on a Remington 870 for tactical, defensive, or competition use.
