GrovTec GTSW189 Picatinny Rail 2.2" 5-Slot AR Stock - Black Hardcoat Anodized

The GrovTec GTSW189 is a compact 2.2" Picatinny rail section built for AR-pattern stocks, adding a clean MIL-STD 1913 accessory mounting point to your rifle. It is precision CNC machined from a single piece of lightweight, solid aluminum, keeping carry weight to a minimum while delivering the strength needed for hard-use applications.

The GTSW189 measures 2.20" long and provides a 5-slot span in the standard MIL-STD 1913 Picatinny pattern. That length is ideal for mounting a variety of compact accessories such as back-up iron sights, short reflex optics, lights, and lasers, while also offering a wide range of eye relief adjustment to accommodate different-length attachments and shooter setups.

Finished in a Type III black hardcoat anodized coating, the GTSW189 is built to resist scratches, corrosion, and the rigors of regular range and field use. Designed specifically for AR-style stocks, this low-profile rail section integrates cleanly onto the rear of your rifle and provides a rugged Picatinny interface wherever you need it.
