Odin Works Adjustable Buffer — AR-15 Rifle-Length | Model OSABSAR15RIFLE | UPC 850048530607

Dial-In Your AR’s Recoil & Reliability the Smart Way (Rifle-Length System)

Fine-tune your rifle’s recoil impulse, cyclic rate, and ejection pattern with the Odin Works Adjustable Buffer for AR-15 Rifle-Length receiver extensions. Unlike fixed rifle buffers, this user-tunable system lets you adjust internal mass so you can match your buffer to your gas system, barrel length, ammunition, and suppressor setup (where legal). The result is a smoother recoil stroke, more consistent lock-back, and flatter sight tracking—all while protecting parts from over-speed wear.

Whether you’re optimizing a precision rig with a 20" barrel, stabilizing a suppressed rifle, or chasing the cleanest ejection pattern for duty reliability, the OSABSAR15RIFLE gives you repeatable, mechanical control over the heart of the action.

Platform: AR-15 • Receiver Extension: Rifle-length (A1/A2-style) • Model: OSABSAR15RIFLE • UPC: 850048530607

Why an Adjustable Rifle-Length Buffer?

• Tune Bolt Speed & Dwell: Add or reduce internal mass to stabilize bolt velocity for your gas port and ammo.

• Cleaner Ejection: Achieve a predictable 3–4 o’clock ejection with fewer flyers and less bolt bounce.

• Suppressor Friendly: Extra mass helps calm gassy setups, softening impulse and promoting reliable return-to-battery.

• Protect Your Parts: Correct bolt speed reduces carrier slam and extractor abuse over high round counts.

• Consistency for Accuracy: A smoother cycle supports a steadier sight picture and faster follow-ups.

Key Features at a Glance

• Rifle-Length Fitment: Designed for rifle-length AR-15 receiver extensions (A1/A2 style)—not for carbine tubes

• User-Adjustable Mass: Modular internals let you configure the buffer weight to your system

• Repeatable Tuning: Serviceable design for experimenting, documenting, and returning to proven setups

• Precision Cycling: Helps mitigate over-gassing, bolt bounce, and erratic ejection

• Premium Build: Odin Works quality components for long service life

• Model / UPC: OSABSAR15RIFLE / 850048530607

Package contents and weight materials may vary by lot. Always refer to the included Odin Works insert for the exact components and orientation.

Who Benefits Most?

• Precision/SPR Builders: Smooth, consistent recoil for stable sight pictures at distance

• Suppressor Users (where legal): Extra mass options to counter backpressure

• High-Round Trainers: Reduce wear and tear while improving reliability

• Duty/Defensive Rifles: Achieve predictable ejection and confident lock-back across ammo lots

Suggested Starting Points (Examples)

Final tuning depends on barrel length, gas port, spring condition, suppressor use, and ammunition. Always verify at the range.

• General Purpose Rifle: Mid-weight configuration for balanced recoil and reliable lock-back

• Precision / Softest Pulse: Slightly heavier stack to slow bolt speed for flatter tracking

• Suppressor / Over-Gassed: Heavier stack to calm impulse, reduce gas-to-face, and steady ejection

Installation Overview (Quick Guide)

1. Verify Unloaded: Remove magazine; visually/physically check the chamber.

2. Open the Receiver: Push out takedown pins and hinge the upper forward.

3. Remove Existing Buffer & Spring: Depress the buffer retainer and extract both.

4. Configure Buffer Mass: Set the internal weights per the Odin Works orientation diagram; cap securely.

5. Install with Rifle Spring: Insert the adjusted buffer + rifle-length spring into the tube; ensure the retainer captures the buffer.

6. Function Check & Range Test: Confirm manual cycling, then test for ejection angle, lock-back, and smooth impulse. Adjust mass as needed.

Pro tip: Change one variable at a time (buffer mass or spring). Record ejection angle and lock-back results for repeatable tuning.

Pro Tuning Tips

• Start in the Middle: Begin with a mid-weight configuration and add mass until ejection stabilizes around 3–4 o’clock.

• Mind the Spring: Use a quality rifle-length spring; springs fatigue—replace as needed and re-tune.

• Ammo Matters: Zero and tune with your intended duty/competition load (suppressed & unsuppressed, if applicable).

• Read the Signs: Forward ejection and harsh impulse often mean too light; short-stroke/weak lock-back often means too heavy or insufficient gas.

Frequently Asked Questions

Q: Will this work in a carbine buffer tube?
A: No. This model is for rifle-length receiver extensions only. Use Odin Works’ carbine-length adjustable buffers for carbine tubes.

Q: Do I need a special spring?
A: Use a rifle-length buffer spring in good condition. If you change spring type/brand, re-verify your tune.

Q: How do I know the tune is right?
A: Look for reliable lock-back on an empty mag, consistent 3–4 o’clock ejection, and a smooth impulse without bolt bounce or excessive carrier slam.

Q: Can I use this with a suppressor?
A: Yes. Heavier configurations often pair well with suppressed rifles to counter added backpressure—confirm reliability with your chosen ammo.

Responsible Use Reminder

After any buffer change, re-zero and function-test with your intended ammunition (suppressed/unsuppressed). Confirm reliable lock-back, consistent ejection, and safe operation before duty or competition use. Always follow firearm safety rules and the manufacturer’s instructions.
