The Luth-AR Fixed AR10 Rifle Complete Buffer Tube Assembly is a ready-to-install recoil management system for AR-10 builds and upgrades. This kit includes everything you need to complete the buffer tube assembly on your .308 rifle — the tube itself, the buffer, and the spring — so there's no hunting around for mismatched parts or making separate orders. If you're assembling an AR-10 from a lower receiver or replacing a worn buffer system, this Luth-AR kit cuts out the guesswork and gets you to the range faster.
Built to Rifle length (A2 standard), this assembly is engineered specifically for .308 rifles and works with A2 fixed buttstocks, making it a straightforward swap for traditional AR-10 platforms. The buffer and spring are sized and weighted for the .308 cartridge, so you get the proper cycling and recoil impulse your rifle needs without having to second-guess compatibility or performance.
Whether you're finishing a precision long-range build, fixing a damaged buffer system, or setting up a new AR-10 from the ground up, having a complete, matched assembly removes a common source of feeding, cycling, or reliability headaches. Luth-AR's no-frills approach means you're getting functional, field-tested components rather than over-marketed hype.
| Rifle Platform | AR-10 (.308) |

Yes. This Luth-AR kit is specifically designed for A2 fixed buttstocks and uses the standard Rifle-length tube that fits that platform.
It's complete. The kit includes the buffer tube, the .308 buffer, and the recoil spring — everything needed for assembly in one box.
This assembly is built for .308 rifles (AR-10 platform). The buffer and spring are weighted and sized specifically for .308 recoil.
No. This is an AR-10 (.308) assembly and is not compatible with AR-15 rifles, which use a different buffer system.
