Midwest Industries Picatinny Stock Tube Buffer Tube Adapter

Description

The Midwest Industries Stock Tube with Buffer Tube Adapter solves a problem a lot of builders run into: you've got a rear Picatinny rail on your receiver but need a way to run a standard buffer tube and stock. This little adapter bridges that gap. It bolts onto a vertical 1913 interface and gives you a clean, direct mounting point for any Mil-Spec receiver extension, opening the door to whatever stock or brace setup you're chasing.

Machined from 6061 aluminum with a hard coat anodized finish, it keeps things light at right around 2.4 ounces while still holding up to real-world use. Midwest builds these in the USA and backs them with a lifetime warranty, which tells you where their confidence sits. The finish shrugs off wear and corrosion, and the compact footprint means you're not adding a bunch of bulk to the back of your gun.

Why the MI-STAP-BT Fixed Adapter Works

This is the fixed, non-folding version, so it doesn't rotate or collapse. That's the point for a lot of folks. A fixed mount means fewer moving parts and a rock-solid connection between your receiver and your stock tube. Owners consistently note that it locks up with no play once torqued to spec, and the install is straightforward if you follow the instructions and get the torque right. If you want a folding option instead, Midwest makes the side-folder variant separately.

Getting the Most From Your Stock Tube Adapter

This adapter is a great match for platforms and chassis builds where a rear Picatinny rail is the only attachment point available, think certain pistol-caliber carbines, AK-pattern guns with a rear rail, and similar setups. Just remember you supply your own Mil-Spec buffer tube and stock or brace, since those aren't part of the package. Get those pieces sorted and this becomes one of the simplest, most reliable ways to finish out the back end of your build.
