The GrovTec Picatinny Rail Adaptor (brand part no. GTSW259) lets shooters mount standard Picatinny rail accessories onto a stock AR-15 forearm without swapping out the factory handguard for a full rail system. Machined from aluminum and finished with a Type III hardcoat anodize, the adaptor is built to hold up to repeated mounting and dismounting of lights, lasers, and other Picatinny-based accessories. An elongated screw slot accommodates a range of hole and slot spacings found across different forearm designs, which widens the number of accessories and mounting positions the adaptor can support. It is a straightforward, low-cost way to add rail space to a rifle that is not already running an aftermarket handguard.
