Lines of Effort
Effort Forend is an AR compatible forend made from bricks or other easily manipulated materials. First suggested by ToledoXJ of ARFCOM and seconded by bigfatdave of The High Road, yet another D/FW denizen clamored for one at the gun show. Below is an unglued Mk1, with a conventional carbine forend up top. No heat shield is installed in the lower part.
