Aim Sports ARPTUB AR-15 Pistol Buffer Tube with Pad, Black

Description

The Aim Sports ARPTUB is the pistol-length buffer tube that gets your AR pistol build over the finish line. Machined from 7075 aluminum, it strikes the sweet spot between light weight and real durability, which is exactly what you want on a component that takes a beating every time the action cycles. The black finish keeps it looking clean, and the included rear pad gives you a bit of contact comfort when you're settling into your setup.

What Sets the ARPTUB Apart

This is a smooth, receiver-extension-style tube built for pistol configurations, so there's no adjustable stock riding on it. The threads are cut to work with a standard endplate and castle nut, which means installation is straightforward if you've built an AR before or watched a couple of good videos. It fits standard AR-15 lowers as well as AR-10/M5 (.308) lowers, so it covers a wide range of builds without you having to hunt down something platform-specific.

Building With the Aim Sports Pistol Buffer Tube

Worth knowing up front: this is the tube only. It does not ship with a buffer, buffer spring, endplate, or castle nut, so you'll want those on hand before you sit down to assemble. That's pretty typical for buffer tubes sold on their own, and it gives you the freedom to pair it with the buffer weight and spring that match your gas system and shooting style. Aim Sports has built a reputation for parts that do the job without draining your budget, and the ARPTUB fits right into that lineup.

If you're piecing together an AR pistol or replacing a worn tube, this is a dependable, get-it-done option. It's backed by a limited lifetime warranty, so you can bolt it on and stop thinking about it.
