LBE Unlimited H2BUFKT Buffer Tube Kit Black AR-Style$96.05
Availability: In Stock
Building or upgrading an AR-platform rifle? The LBE Unlimited H1BUFKT Buffer Tube Kit gives you all the core components you need in one package. This complete buffer system includes a six-position mil-spec diameter buffer tube, carbine-length recoil spring, H1 heavy recoil buffer, mil-spec receiver end plate, and castle nut—everything required to assemble a functional, reliable receiver extension without hunting down individual parts from multiple suppliers.
The H1 buffer is the heavier option in the buffer weight spectrum, making it well-suited for rifles running heavier ammunition or those with specific tuning needs. Pair it with the included carbine-length spring for a tested, factory-standard configuration. LBE Unlimited parts are built for shooters and builders who expect their components to hold up through years of range days, hunting trips, and serious use—no shortcuts in manufacturing or material quality.
Whether you're assembling an AR from a stripped lower, replacing a worn-out buffer system, or setting up a dedicated hunting or target rifle, this kit eliminates the guesswork and gets you a complete, mil-spec-compliant assembly. All components ship together so you're ready to start building or upgrading without back-ordering.

The six-position mil-spec diameter buffer tube is the standard size used across virtually all commercial AR stocks and stabilizing braces. If your stock or brace is mil-spec compatible, this kit will fit.
The H1 is a heavier buffer weight, which can help reduce felt recoil and adjust cycling behavior, especially useful with heavier ammunition loads or when fine-tuning your rifle's performance. Lighter buffers are typically used with lighter ammunition or to increase cycling speed.
Yes. The kit includes the buffer tube, recoil spring, H1 buffer, receiver end plate, and castle nut—all the internal components needed for a complete, functional assembly.
Absolutely. LBE Unlimited components are built for serious shooters and builders. This kit works equally well for hunting rifles, range guns, or any AR-platform build where reliability and durability matter.
