GTSW238) is a rail attachment built to bring 1913 Picatinny compatibility to an M-LOK handguard for mounting lights, vertical grips, and other rail-based accessories. GrovTec machines this section from solid aluminum and finishes the ends with a bevel that reduces snagging and eliminates the sharp corners and edges that plain-cut rail sections leave behind.
