Forward Controls Design A1 Short AR15/M16 AR Grip Black. Largely based on the A2 TDP specs GSA is available in GSA1 (without finger groove). Shortened by 0.375in GS retains the A2's 25 degree angle. We added angled thumb shelves on both sides of the grip for improved ergonomics and grip retention over the A2 grip. GSA is designed for shorter weapons its shorter length means it will not fit large hands. Generally speaking GSA is a great fit if the user's hand is 4 inch wide or less. Both GSA versions are flared at the bottom of the front strap and serrated on the front and rear straps. The sides don't have the cross hatch panels found on the A2 but they are not smooth as the material itself has a semi rough texture for traction. Like the A2 GS doesn't have storage. There are plenty of AR15/M16 grips with storage feature GS is meant to be an A2 replacement hence it's kept many of the A2's design choices such as single piece non-modular design grip angle and absence of storage. For ourselves Forward Controls Design doesn't want to make the AR into a storage platform there are other and often better places to store things than the pistol grip. GSA is shipped with a SOLGW's grip screw and grip screw washer. Compatible with FN SCAR16 and SCAR17.
