SIONICS handguards are incredibly rigid and the inherent design features ensure anti-rotation. Through rigorous testing both by SIONICS and the many LE agencies using SIONICS rifles we can ensure zero retention when using IR/VIS aiming devices.

SIONICS handguards feature QD attachment points at the forward and rear 3 and 9 o’clock positions. SIONICS QD receiver sockets are anti-rotational.
