Strike Industries Carbine Pistol Receiver Extension, Red Anodized

Description

If you're piecing together an AR pistol build and want a buffer tube that looks as sharp as it runs, the Strike Industries Carbine Pistol Receiver Extension checks the boxes. It's cut from 7075-T6 aluminum, which is the same aircraft-grade stuff you'll find on hard-use gear, giving it a real strength advantage over the more common 6061 tubes you'll see floating around. The red Type II anodized finish is the eye-catcher here, a clean pop of color that stands out on a black rifle without shouting.

What Sets the CARPRE Slick Apart

Strike built this one for folks who take their AR pistol platform seriously rather than treating it as a range toy. The Slick profile keeps the whole exterior smooth and snag-free, which matters when you're sliding an aftermarket brace over it. That smooth outer surface is designed to accept popular pistol braces and Strike's own Viper Pistol Stabilizer, so you've got flexibility on how you finish the build.

Features That Earn Their Keep

Inside, you get a supported anti-rotation buffer retaining plunger that locks things down and keeps your buffer where it belongs. Out back, there's a QD socket machined right into the tube plus a sling swivel point, so you can run a single-point setup and get that push-pull operation dialed in for tighter shooting positions. It fits onto any standard AR receiver, which keeps the install straightforward.

Fitment Notes Before You Build

This is a carbine-length pistol extension, so it works with carbine-length buffer springs and buffer weights. It's purpose-built for pistol braces and stabilizers rather than adjustable rifle stocks, and it's not intended for AR10 or LR308 platforms. Match it with the right carbine buffer and spring and you've got a solid, good-looking foundation for a compact PDW-style build.
