GrovTec GTSW190 3.8" 9-Slot AR Stock Picatinny Rail - Black Anodized

The GrovTec GTSW190 is a compact 3.8" AR stock-mounted Picatinny rail that adds 9 full mounting slots in the MIL-STD 1913 pattern to the rear of your rifle. Built for shooters who want extra mounting real estate at the buttstock position, this rail installs onto a compatible AR-style fixed stock and provides a full row of standard Picatinny space without adding excess bulk or weight.

Each rail is precision CNC machined from solid aluminum for an excellent strength-to-weight ratio, then finished in a durable Type III Black Hardcoat Anodized coating for corrosion and wear resistance in the field. The standard MIL-STD 1913 Picatinny slot pattern accepts any compatible accessory, and the rail ships with the necessary mounting hardware so it's ready for immediate installation.
