Compact Power: Strike Industries Pistol Buffer Tube

The Strike Industries Pistol Buffer Tube delivers enhanced functionality and reduced overall length for your AR-style pistol or personal defense weapon. Machined from rugged 7075-T6 aluminum, this receiver extension offers greater strength than standard 6061 tubes.

Equipped with a supported buffer retainer and an anti-rotation tab, the SI Pistol Buffer Tube ensures a secure, wobble-free connection. The included tungsten-filled buffer and flat-wire spring optimize reliable cycling over the long haul.

An integral QD socket at the rear of the tube enables efficient “push-pull” sling operation, further enhancing your PDW’s versatility. Measuring just over 5 inches in length, this compact design helps minimize your firearm’s overall footprint.

Whether you’re running the Strike Industries Pistol Stabilizer or another compatible brace, the SI Pistol Buffer Tube provides a sturdy, reliable foundation. Unlock the full potential of your AR pistol with this premium hardware upgrade.
