Here at SIONICS, we test fire EVERY BCG, upper receiver group, and firearm.

Our test firing process is simple:

• BCGs get 5 rounds of M193 and another single round in a separate magazine to ensure function, ejection pattern, and lock-back.
• All upper receiver groups and firearms get 7 rounds of M193 and another single round in a separate magazine to ensure function, ejection pattern, and lock-back.

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.
