AR-15 Gas Block Front Sight No Lug .750 Steel Black

Immediate Response Sighting For Tactical Emergencies

Multi-purpose front sight works as a fully functional gas block, plus delivers lifesaving backup when primary optics fail or become hindered by low light or poor weather conditions. Machined, steel body features a spring-loaded pushbutton that locks sight in the deployed position. When not in use, simply depress the button and fold down for an unobstructed view through your optics. Protective ears guard the sight post from blows incurred during duty. Split, barrel clamp design allows easy mounting to standard contour barrels without removal of flash hiders or muzzle brakes. Hex cap screws pull clamping halves tight to barrel for complete sight immobilization when properly tightened. Durable, mil-spec, phosphate finish resists rust and corrosion. YHM-9394 includes bayonet lug and pivoting sling swivel that accepts tactical slings up to 1¼" wide. Rubber coating prevents swivel from rattling and giving away your position while on patrol. YHM-9395 has sling swivel, no bayonet lug. YHM-9835A has Picatinny-style under-rail that accepts lights, lasers, and other forward-mounted accessories. No sling swivel.
