Odin Works Adjustable AR-10 Buffer — tungsten, stainless and aluminum weights, 3.45 to 4.65 oz, .308 Win 7.62x51 platform, 100% USA made Southern Idaho

The AR-10 is a fundamentally different cycling equation than the AR-15 — more mass, more gas pressure, more BCG energy to manage. Getting the buffer weight right on a .308 Win or 7.62x51 AR-10 is critical for reliability, brass life, and felt recoil. The Odin Works Adjustable AR-10 Buffer gives you 3 interchangeable weights — aluminum, stainless steel, and tungsten — covering a 3.45 to 4.65 oz range in a stainless steel body built specifically for the large-frame AR platform. Stop guessing. Start tuning. 100% USA made in Southern Idaho.

3-Weight System

Precision Tuning for the Large-Frame AR

The AR-10 buffer includes 3 weights — one of each material — covering the precise range the .308/7.62 platform demands. Load any combination of the 3 included weights to dial in your exact configuration.

AL Aluminum × 1 Light end — 3.45 oz minimum config

SS Stainless × 1 Mid-weight — intermediate tuning

W Tungsten × 1 Max weight — 4.65 oz heavy config

Why AR-10 Buffer Weight Is Critical

The AR-10 platform runs at significantly higher bolt thrust and gas pressure than the AR-15. An AR-10 that's running too light a buffer will slam the BCG rearward aggressively — beating up your receiver, your bolt, and your brass. Too heavy and it short-strokes. The Odin Works adjustable system lets you find the exact weight your specific AR-10 needs based on your gas system, barrel length, and ammunition — without buying three different fixed-weight buffers to get there.

Key Features

Large-Frame AR. Precisely Tuned.

◆Stainless steel body — heavy-duty construction built for the higher bolt thrust and cycling energy of the AR-10 / .308 platform. More durable than aluminum for large-frame applications.
◆3 interchangeable weights — aluminum (lightest), stainless steel (mid), tungsten (heaviest). One of each, giving you precise control across the 3.45–4.65 oz range.
◆3.45 to 4.65 oz range — covers the full practical buffer weight range for AR-10 and .308 builds. Whether you're running a 16" mid-length or a 20" rifle-length gas system, the Odin Works adjustable covers it.
◆Face-mounted set screw adjustment — swap weights from the front without punching out roll pins or disassembling the buffer. Change your configuration at the range in seconds.
◆Compatible with .308 Win, 7.62x51 NATO, and other AR-10 platform calibers — fits standard AR-10 rifle-length buffer tubes.
◆Recoil management — properly matched buffer weight reduces felt recoil and muzzle rise on the AR-10 platform significantly. Faster follow-up shots, better brass retention, longer component life.
◆100% USA made — designed and manufactured by Odin Works in Southern Idaho. Lifetime warranty.
