Odin Works H-FRB Heavy Buffer and Spring for Forced Reset Triggers Fits AR-9 Stainless Body 8.6oz Silver OS-BS-HFRB-9 UPC 850048530911
Product Description
The Odin Works H-FRB Heavy Buffer and Spring System (OS-BS-HFRB-9) is a specialized recoil management kit engineered specifically to solve timing, bolt bounce, and cycling reliability challenges in 9mm pistol-caliber carbines (AR-9s) equipped with Forced Reset Triggers (FRTs) or high-rate-of-fire control groups. Designed to tame the harsh direct-blowback impulse inherent to 9mm PCC platforms, this kit slows down the cycling cadence just enough to ensure clean trigger resets, positive ejection, and reliable feeding during rapid-fire strings.
Precision CNC-machined from solid stainless steel, the heavy 8.6 oz buffer housing features dense internal dead-blow weights that absorb secondary bolt bounce as the action locks back forward. Paired with an included high-performance flat wire recoil spring, the system delivers consistent compression resistance across the entire stroke. Flat wire springs store significantly more energy than standard round wire springs while eliminating "buffer tube twang" noise and maintaining tension over thousands of rapid cycles.
Engineered to work seamlessly with extended PCC bolt carrier groups, the Odin Works OS-BS-HFRB-9 provides the ideal weight-to-spring-rate ratio needed to prevent premature unlocking, primer smearing, and out-of-battery malfunctions on high-performance AR-9 builds. Upgrade your PCC with American-made precision designed specifically for hard-use forced reset trigger applications.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits standard carbine-length buffer tubes (receiver extensions) on 9mm AR-9 pistol-caliber carbines and AR-9 pistols using blowback bolt carrier assemblies. Specially tuned for setups utilizing Forced Reset Triggers (FRT), binary triggers, or full-auto BCGs.
- Perform a complete firearm safety check: drop the magazine, lock the bolt rearward, and visually inspect the chamber to verify zero live rounds are present.
- Depress the rear takedown pin and pivot the upper receiver away from the lower receiver.
- Depress the buffer retainer pin inside the lower receiver extension and carefully remove the existing recoil spring and buffer.
- Clean any excess grease, carbon buildup, or debris from the internal channel of the carbine buffer tube.
- Slide the included Odin Works flat wire spring onto the OS-BS-HFRB-9 8.6oz stainless heavy buffer.
- Insert the assembly into the buffer tube until the buffer retainer pin snaps up to hold it in place, reassemble the receivers, and perform a manual action rack and trigger reset test before live fire.
Key Features
- Tuned for Forced Reset Triggers: Calibrated weight and spring tension resolve bolt bounce and timing issues during high-rate-of-fire operation.
- 8.6 oz Heavy Stainless Steel Buffer: Dense stainless steel body and internal dead-blow weight matrix dampen violent direct-blowback recoil impulse.
- Included Flat Wire Recoil Spring: Provides smoother, more uniform energy storage while reducing buffer tube operating noise.
- Prevents Out-Of-Battery Malfunctions: Maintains forward bolt pressure to guarantee positive lockup and reliable primer ignition.
- Corrosion-Resistant Silver Finish: All-stainless body resists carbon fouling, harsh cleaning chemicals, and moisture.
- Made in the USA: Precision-manufactured in Idaho to demanding tolerances for competition and hard-use PCC builds.
