This skeletonized aluminum vertical foregrip mounts to any MIL-STD-1913 Picatinny rail and gives you a positive forward hold while keeping weight to a minimum. The aluminum body is cut out to shed mass, so it adds control without making the front of your rifle or carbine feel heavy. Fit: Any standard Picatinny rail section, including railed handguards and Picatinny segments bolted to M-LOK or KeyMod handguards. This grip clamps to Picatinny and does not mount directly to M-LOK slots; if your handguard is M-LOK only, add a short Picatinny rail section first. Finish: Aluminum construction with a skeletonized profile. Features: Skeletonized aluminum body Vertical foregrip design for a positive forward hold Clamp-on MIL-STD-1913 Picatinny mount Lightweight construction Check that you have enough open rail length where you want the grip, tighten the clamp securely, and re-check it after your first range session, since clamp-style mounts can settle under recoil and handling.
