The GrovTec 3.8-Inch 9-Slot Rail (brand part number GTSW190) is a Picatinny rail section built to mount to an AR-platform stock. It is precision CNC-machined from solid aluminum and finished in a Type III black hard anodized coating, following the MIL-STD-1913 Picatinny pattern so lasers, sights, scopes, or other rail-compatible accessories can be mounted directly to the stock. At 3.8 inches with 9 slots, it gives more usable rail space than GrovTec’s shorter 5-slot options for shooters who need to mount more than one accessory.
