    Odin Works Adjustable AR-15 Lite Buffer — 7 interchangeable weights, 2.1 to 4.2 oz, aluminum body, 100% USA made Southern Idaho, competition and lightweight AR-15 builds

    Not every AR-15 build needs to go heavy. Competition shooters, lightweight builds, and overgassed rifles need a buffer solution that goes in the other direction — lighter, faster, and just as precisely tuned. The Odin Works Adjustable AR-15 Lite Buffer gives you a 2.1 to 4.2 oz range with 7 interchangeable weights — 3 aluminum, 3 stainless steel, and 1 tungsten — in an aluminum body built for speed-focused AR-15 builds. One buffer. Every configuration from featherweight competition to H2 equivalent. 100% USA made in Southern Idaho.


    Weight System

    3 Weight Types. 7 Combinations.

    AL Aluminum × 3 Lightest — competition, light loads, over-gassed systems
    SS Stainless × 3 Mid-weight — general purpose, standard mil-spec loads
    W Tungsten × 1 Heaviest — max weight for the lite platform at 4.2 oz
    2.1 oz Min — 3× AL Lightest possible. Competition loads, over-gassed builds.
    2.8 oz 2 AL + 1 SS Light-medium. Standard competition carbine builds.
    3.0 oz Carbine Equiv. Standard carbine weight. Mil-spec starting point.
    3.5 oz H1 Range 1 AL + 2 SS. Standard defensive and duty weight.
    4.2 oz Max — H2 Equiv. 2 SS + 1 Tungsten. Max lite weight. FRT minimum threshold.
    Lite vs. Heavy — Which Do You Need?

    The Lite buffer covers 2.1–4.2 oz — ideal for competition builds, lightweight AR-15s, overgassed rifles, and shooters who run lighter loads. The Heavy buffer covers 3.7–5.8 oz — required for forced reset triggers, suppressed builds, pistol-length gas, and high-pressure loads. If you're running an FRT like the Disruptor or ARC-Fire V2, you need the Heavy. If you're building a lightweight competition or 3-Gun rifle, the Lite is your answer.


    Key Features

    Built for Speed and Precision

    • Aluminum body — lightweight construction keeps your build as light as possible while still giving you tuning flexibility. Significantly lighter than the steel-body Heavy version.
    • 7 interchangeable weights — 3 aluminum, 3 stainless steel, 1 tungsten. Choose any 3 for your configuration. Load any combination via the face-mounted set screw — no punches, no roll pins.
    • 2.1 to 4.2 oz range — from the lightest competition weight all the way to H2 equivalent. Covers every lightweight AR-15 configuration in a single buffer body.
    • Competition and 3-Gun optimized — the 2.1 oz minimum weight allows your AR-15 to cycle light competition loads that would short-stroke in a heavier buffer. Run lighter ammo without reliability issues.
    • Over-gassed rifle solution — if your AR-15 runs rough, beats up brass, or has excessive muzzle rise with factory ammo, you're likely over-gassed. Dropping to a lighter buffer slows the cycle and smooths out the action.
    • Set screw adjustment — swap weights in seconds from the front of the buffer. No disassembly, no special tools. Change your configuration at the range between stages.
    • Mil-spec carbine tube compatible — drop-in installation in any standard mil-spec AR-15 carbine buffer tube. No modification required.
    • 100% USA made — designed and manufactured by Odin Works in Southern Idaho.
