ODIN Works · Southern Idaho — 100% USA Made
Aluminum body · 7 interchangeable weights · Mil-spec AR-15 carbine tube compatible
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.

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.
