Elevate Your PDW Build: Strike Industries Carbine Length Pistol Buffer Tube

Crafted from robust 7075-T6 aluminum, this buffer tube offers a major upgrade over standard 6061 models. Featuring a supported, anti-rotation buffer retaining plunger, the CARPRE provides a secure interface for your AR pistol’s stock or stabilizer. A convenient sling swivel is machined into the rear, enabling efficient “push-pull” operation.

This “Slick” version boasts a smooth, streamlined profile, allowing for the seamless integration of popular aftermarket pistol braces, including Strike Industries’ own Pistol Stabilizer. Built-in QD sockets at the end plate and rear of the tube further enhance your sling attachment options.

Fully compatible with carbine-length buffer springs and weights, this receiver extension is not suitable for use with adjustable stocks or rifle-length components. As always, know your state and local laws before proceeding with any build.
