Description Warranty Policy & Prop. 65 Warning
 

The ODIN Works Heavy Buffer is built to run with Forced Reset Triggers. It offers a simplified, performance-driven approach to firearm tuning, delivering consistent cycling and recoil control without the need for adjustment. Designed to run smoothly on a variety of setups, this buffer achieves increased weight and pairs with a proprietary spring for reliable operation.

Helps manage recoil impulse, reduce wear on moving components, and and aid in reliable cycling with an FRB in AR-15 platforms.

*Includes proprietary spring


NOTE: Due to the wide variety of AR-platform configurations, the ODIN Works H-FRB Buffer may not function optimally in every firearm with an aftermarket Forced Reset Triggers. Some rifles may require adjustments to the gas system, buffer weight, spring, or other operating components to achieve reliable performance. As with any performance upgrade, proper tuning may be necessary based on your specific firearm configuration and ammunition.

H-FRB (AR-15) should only be used on firearms with barrels over 10"

    FAQs:

    H-FRB Buffer FAQs


    What is the H-FRB Buffer designed for?
    • The H-FRB Buffer is designed to help tune AR platforms running forced reset trigger systems. It is intended to support reliable cycling when the firearm, trigger, spring, buffer tube, ammunition, and gas system are correctly matched.

    Will the H-FRB Buffer work in every rifle?

    • No. Forced Reset Trigger systems often require tuning, and what works in one rifle may not work in another. Barrel length, gas system, buffer tube, spring, ammunition, suppressor use, and trigger setup can all affect performance.

    What buffer tube does the H-FRB Buffer use?
    • The H-FRB AR-15 buffer is designed for a carbine-length buffer tube. Always confirm the exact H-FRB model and your firearm setup before ordering.

    Does the H-FRB9 work with folding stocks or non-standard buffer tubes?

    • The H-FRB9 is intended for standard buffer tube setups. Folding stocks, adapters, and non-standard tubes may affect fit and function. If your setup is unusual, contact ODIN Works before ordering.

    Do I need a spacer with the H-FRB Buffer?
    • Most customers should not assume a spacer is needed. If the carrier gets stuck to the rear or the buffer seems too short, confirm your buffer tube, spring, trigger, and platform setup before modifying anything.

    Will the H-FRB Buffer make my rifle run perfectly out of the box?

    • Not always. Forced Reset Trigger setups usually need tuning. If your firearm short-strokes, sticks, fails to reset, or only runs in semi-auto, the system may need adjustments to the buffer, spring, gas, ammunition, or trigger setup.

    What information should I provide if I need help tuning my H-FRB setup?

    • Please include your firearm platform, caliber, barrel length, buffer tube type, spring, trigger model, buffer model, ammunition, suppressor use, and the exact issue you are seeing.

    Why is my rifle short-stroking with an H-FRB Buffer?

    • Short-stroking can be caused by several factors, including buffer weight, spring choice, gas setting, ammunition, suppressor use, or trigger/BCG interaction. Start by confirming your full setup and symptoms before replacing parts.

    Can I use the H-FRB Buffer with a suppressed rifle?

    • Possibly, but suppressed rifles often require additional tuning. Suppressors can change gas pressure and cycling speed, so you may need to adjust your gas system, spring, or buffer setup.

    Do you offer military or veteran discounts on H-FRB Buffers?

    • ODIN Works offers qualifying military/veteran discounts. Customers may be asked to provide DD-214 or other qualifying credentials before the discount is applied.

    Can dealers or bulk buyers purchase H-FRB Buffers?

    • Yes, dealer or bulk purchase inquiries can be reviewed by ODIN Works. Please contact us with your business information, quantity needed, and any dealer credentials.

    Can I cancel or change my H-FRB order after placing it?

    • Contact ODIN Works as soon as possible. If the order has not shipped, we may be able to help. If it has already shipped, standard return or exchange policies may apply.

    Can I return or exchange an H-FRB Buffer if I ordered the wrong one?

    • Contact ODIN Works with your order number and the product you meant to order. If eligible, support can help determine the correct exchange or return path.

5 of 5 Simply BETTER than the rest Saturday, September 5, 2026
Reviewer: Kurt from GA United States  
Just buy the thing already! Its worked in 50+ installs so far without a single issue. Tuning is required for ALL reset triggers, and this makes it Simple Stupid Easy.
