The GrovTec Push Button Rail Base for KeyMod, 3.1 inches with 5 slots (brand part no. GTSW231) is a rail attachment built to bring 1913 Picatinny compatibility to a KeyMod 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. Its push-button base design adds a quick-release option beyond a standard fixed rail section, in a compact 3.1 inch footprint with five full slots.
