The LBE Ar Milspec Buffer Tube Kit in brown is a complete, US-made carbine-length recoil system for AR-15 platform rifles. Whether you're building a new AR, replacing worn internals, or swapping uppers between lowers, this mil-spec buffer tube assembly gives you everything needed to manage recoil and cycle your rifle reliably. LBE Unlimited has earned a reputation for no-nonsense, American-made gun parts—the kind you can count on whether you're at the range, in the field, or running drills.
This isn't a stripped-down kit that leaves you hunting for missing parts. The buffer tube assembly comes complete: a six-position mil-spec diameter tube (the industry standard for AR carbines), a carbine-length recoil spring, a standard carbine buffer, the receiver end plate, and the castle nut. All the pieces fit together and do the job. Brown finish blends with most modern AR furniture and resists corrosion in the field.
Drop this kit into a lower receiver and you've got a functional stock assembly. No guessing at compatibility—mil-spec means it plays nice with standard AR-15 lowers and aftermarket stocks. LBE parts are made in the USA, which matters if you care about where your gun parts come from and want to support domestic manufacturing.

Yes. This is a mil-spec diameter buffer tube, which is the standard for AR-15 carbine-length stock assemblies. It will drop into any standard mil-spec lower receiver. If you have a commercial-diameter lower (less common), this kit won't fit—but nearly all modern AR lowers are mil-spec.
You get the buffer tube itself, a carbine-length recoil spring, a standard carbine buffer, the receiver end plate, and the castle nut. It's a complete assembly—no trips back to the parts bin.
Yes. The buffer tube has six positions, so you can adjust the length of pull to fit your body or preferred shooting setup.
The buffer tube itself is mil-spec, so it will accept any mil-spec stock. You may not need the entire kit if you already have a stock; the tube, spring, and buffer are the working parts if you just need to replace internals.
