The Luth-Ar A1 Buttstock Kit for AR-15 is a complete, ready-to-assemble stock upgrade that gives your rifle a classic, proven design in a modern package. This kit bundles everything needed to swap out or build a traditional A1-length stock setup: the stock itself, buffer tube, buffer, and spring all together so you're not hunting parts individually. It's ideal for builders who want the ergonomic familiarity and clean lines of the original A1 profile without sacrificing contemporary materials and durability.
The A1 stock is molded from glass-filled nylon, a material strong enough to handle repeated shooting cycles without the added weight of a foam core. This construction keeps things light while maintaining the rigidity needed for consistent shouldering and reliable recoil management. The stock arrives with an attachment screw pre-fitted in the trap door, removing one more thing from your assembly checklist. Whether you're building a retro-inspired rifle, setting up a dedicated .223/5.56 platform, or simply prefer the compact length and classic aesthetics of an A1 design, this kit streamlines the process and pairs quality components in one go.
Available in black, the Luth-Ar A1 kit appeals to AR-15 owners who value both form and function—shooters who appreciate the reliability of mil-spec proportions and the convenience of buying matched, compatible parts rather than sourcing them separately. It's a straightforward upgrade path for anyone building a no-nonsense rifle or refreshing a worn stock assembly.
| Stock Model | A1 (BS-A1) |
| Buffer Tube | BS-09 Extension Tube |
| Buffer | BS-11 (.223/5.56 Rifle Buffer) |
| Spring | BS-10B (.223/5.56 Rifle Buffer Spring) |
| Stock Material | Glass-filled nylon |
| Color | Black |
| Includes | A1 stock, extension tube, buffer, spring, attachment screw |
This kit is designed for AR-15 platforms chambered in .223/5.56 and uses standard mil-spec buffer tube dimensions. Confirm your rifle accepts standard buffer tube assemblies before ordering. The A1 length is shorter than modern commercial or mil-spec carbine lengths, so make sure the A1 profile fits your intended build or use case.
The kit includes the A1 buttstock (BS-A1), extension tube (BS-09), .223/5.56 buffer (BS-11), .223/5.56 spring (BS-10B), and a screw for attaching the stock to the tube. Everything needed to install a complete A1-length assembly is in the box.
No. The A1 stock is manufactured from glass-filled nylon, which provides sufficient strength and rigidity without a foam insert. This keeps the stock lighter while maintaining durability under normal shooting conditions.
Yes. This kit is well-suited for AR-15 builders and is a convenient way to acquire all four essential components at once rather than sourcing them individually.
