Description
The Luth-AR A2 Buttstock is the go-to fixed stock for anyone building a classic rifle-length AR-15 or refreshing an old M16A2-style setup. It carries the traditional A2 profile that plenty of folks grew up shooting, with a longer length of pull that suits a bladed or prone stance and gives you a rock-solid cheek weld every single time. Because there's nothing to collapse or adjust, you get a rigid, no-wiggle platform that stays put shot after shot, which is exactly what you want for steady long-range or precision work.
What Sets the Luth-AR A2 Stock Apart
Luth-AR builds this one from 33% glass-filled nylon, and it's foam filled inside, so it shrugs off knocks and general field abuse without feeling cheap or hollow. It's made in America and cut to true Mil-Spec A2 dimensions, meaning it drops onto a standard rifle-length buffer tube the way the original design intended. The butt plate includes a polymer trap door that opens up a small storage compartment, handy for a spare battery, cleaning gear, or a little survival kit.
Fitting the A2 Mil-Spec Buttstock to Your Build
This is a rifle-length stock, so it pairs with an A2 rifle buffer tube, a rifle buffer, and a rifle-length spring. A carbine buffer tube or carbine stock won't cross over here, so keep your parts matched to the rifle-length system for smooth cycling. One thing worth noting before you order: the stock itself does not include the A2 screw or the aluminum spacer, so if your build doesn't already have those, grab them at the same time or step up to Luth-AR's complete A2 buffer kit.
Whether you're cloning a retro rifle, putting together a designated marksman build, or just prefer the dependable simplicity of a fixed stock, this Luth-AR A2 delivers old-school ergonomics with modern, low-maintenance materials.

Frequently Asked Questions
Does the Luth-AR A2 buttstock come with the screw and spacer?
No, the stock does not include the A2 stock screw or the aluminum spacer. If your rifle-length buffer tube setup doesn't already have these, you'll want to pick them up separately. Luth-AR also sells a complete A2 buffer kit that bundles the spacer, tube, buffer, and spring if you're building from scratch.
What buffer tube does this A2 Mil-Spec stock fit?
It's a rifle-length stock, so it fits a standard A2 rifle buffer tube. That tube is longer than a carbine tube and uses a rifle buffer with a rifle-length spring. Carbine tubes and carbine stocks are not interchangeable with this one, so keep your parts matched to the rifle-length system.
Is the Luth-AR A2 stock durable enough for regular range use?
Yes. It's molded from 33% glass-filled nylon and foam filled inside, which gives it a solid, dense feel that holds up to repeated range trips and field handling. It's made in America to Mil-Spec A2 dimensions, so it's built to the same standard as the original fixed stocks.
Does the A2 buttstock have any storage?
It does. The butt plate features a polymer trap door that opens into a small internal compartment. It's a good spot for a spare battery, small cleaning tools, or a compact emergency kit.
