Description
Strike Industries treats the AR pistol like a serious platform, not a range toy, and this carbine-length receiver extension backs that up. It's machined from 7075-T6 aluminum instead of the cheaper 6061 you'll find on a lot of budget tubes, so it holds up better under repeated cycling and hard use. The FDE finish here is a Type II anodize that matches nicely with earth-tone builds and other Strike Industries parts.
What the Slick Carbine Pistol Receiver Extension Brings to Your Build
The "Slick" profile means a completely smooth exterior with no fins or steps to catch on gear, clothing, or a bag when you're pulling the gun in and out. That clean shape also makes it a versatile mounting surface, so it plays well with most popular aftermarket pistol braces and stabilizers, including Strike's own Viper Pistol Stabilizer. A supported, anti-rotation buffer retaining plunger keeps everything indexed and locked where it should be.
Sling Setup and QD Mounting Points
One of the smarter touches is the QD sling story. There's a machined sling swivel point at the rear plus QD sockets in both the end plate and the back of the tube, which opens up ambidextrous sling attachment and makes push-pull shooting a lot more natural. If you run a single-point or two-point setup on a compact PDW-style build, this gives you flexible anchor points without adding bulk.
Fitment Notes Worth Knowing
This is a carbine-length tube, so it's built to run carbine-length buffer springs and buffer weights, and it threads onto any standard mil-spec AR15 lower receiver. It is not made for adjustable stocks, rifle-length buffer components, or AR10 and LR308 platforms. Plan your buffer, spring, and brace around a carbine-length pistol setup and this tube slides right into place.

Frequently Asked Questions
What buffer and spring do I need for the Strike Industries carbine pistol receiver extension?
This tube is built to run carbine-length buffer springs and carbine-length buffer weights. It is not compatible with rifle-length buffer components or pistol-length springs. Match your buffer setup to a carbine-length pistol configuration and you're good to go.
Does this receiver extension fit a standard AR15 lower?
Yes, it threads onto any standard mil-spec AR15 receiver. It is not designed for AR10 or LR308 platforms, and it isn't made to work with adjustable, collapsible stocks since it's specifically a pistol receiver extension for braces and stabilizers.
Will pistol braces mount to the slick version?
The slick profile has a smooth, uniform exterior that accepts most popular aftermarket pistol braces and stabilizers, including the Strike Industries Viper Pistol Stabilizer. The lack of fins or ridges is what makes it so flexible for brace fitment. Just confirm your specific brace is rated for a standard-diameter carbine tube.
How does the QD sling mounting work on this tube?
There are QD sockets built into both the end plate and the rear of the buffer tube, plus a machined swivel point at the back. That gives you ambidextrous sling options and makes push-pull operation on a compact build feel natural. It's a handy setup for single-point or two-point slings without adding extra hardware.
