Odin Works H-FRB Heavy Buffer

Forced Reset Trigger · AR-15 · 6.2 oz · 303 Stainless · Carbine-Length Buffer Tube · Proprietary Spring Included The Odin Works H-FRB is a 6.2 oz heavy buffer designed for AR-15 platforms running forced reset triggers. 303 stainless steel body. Designed for carbine-length buffer tubes. Proprietary spring included—must be used with the included spring. Minimum barrel length: 10". Compatible with standard AR-15 platforms. Note: Forced reset trigger setups often require tuning. The H-FRB may not function optimally in every AR-15 configuration. Barrel length, gas system, buffer tube, spring, ammunition, suppressor use, and trigger setup can all affect performance. Tuning of the gas system, buffer weight, spring, or other components may be necessary based on your specific firearm configuration. Contact Odin Works if assistance is needed.

6.2 oz Stainless Body

303 stainless steel body at 6.2 oz. The increased weight aids cycling reliability with forced reset triggers and high-rate-of-fire applications. Reduces wear on moving components.

Carbine-Length Buffer Tube

Designed for standard carbine-length buffer tubes. Not intended for folding stocks, adapters, or non-standard buffer tube setups without confirming fitment with Odin Works first.

Proprietary Spring Included

Includes proprietary spring—must be used with the H-FRB, not a standard carbine spring. The proprietary spring is part of the system's designed operating parameters.

10" Barrel Minimum

H-FRB AR-15 should only be used on firearms with barrels over 10". Use on shorter barrels is not recommended.

Tuning Note

Forced reset trigger systems typically require tuning. Short-stroking, sticking, failure to reset, or semi-auto-only behavior may indicate the need for gas system, spring, buffer, or ammunition adjustments. Confirm full setup—platform, caliber, barrel length, buffer tube, spring, trigger model, ammunition, and suppressor use—before replacing components.
