LBE Unlimited H2BUFKT Mil-Spec AR-Style Buffer Tube Kit with H3 Heavy Buffer – Black

Build or restore your AR-style rifle with confidence using the LBE Unlimited H2BUFKT Buffer Tube Kit in black. This comprehensive kit includes everything you need for a reliable carbine-length recoil system in one convenient package. The six-position mil-spec diameter buffer tube provides a solid, industry-standard fit compatible with mil-spec stocks and components. Paired with a carbine-length recoil spring, H3 heavy recoil buffer, receiver end plate, and castle nut, this kit delivers a complete recoil assembly solution right out of the box.

The H3 heavy buffer is an excellent choice for shooters looking to tame felt recoil, reduce bolt bounce, and improve cycling reliability — particularly on builds with suppressed configurations, overgassed systems, or heavier loads. LBE Unlimited is known for producing dependable, mil-spec AR components at accessible price points, making this kit a smart pick for builders, upgrades, and replacements alike.
