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 blowback PCC 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 an (included) proprietary flat wire spring for reliable operation.

Aids in reliable cycling with an FRT in AR-9 platforms, manages recoil impulse, and reduces wear on moving components.

NOTE: Due to the wide variety of AR-platform configurations, the ODIN Works H-FRT Buffer may not function optimally in every firearm with an aftermarket FRT. 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.

*Includes proprietary flat wire spring

1 of 5 FRT Buffer July 5, 2026
Reviewer: JJ from America  
I was excited to receive these but completely disappointed with the outcome. Fit one in and nothing, no bang, no nothing, failed to even fire semi, much less with a FRT. Swapped back out to the H3 and flawless, I have to return them as they are paperweights right now.

5 of 5 H-FRT9 Heavy Buffer June 11, 2026
Reviewer: JakeE from Pickens, SC United States  
Not much of a review here, I’ve only put about 200 rounds down range with this system, but it does seem to function very well. I just built a full Aero/Ballistic Advantage 8.3” AR9, and this is the buffer/spring I threw in, with the intention of putting in a super safety down the road. The only issues I had seem to be ammo related, tried multiple 147 grain rounds, and the one that fired without issue was blazer brass, has feeding issues with Remington UMC and Fiocchi 147’s, but it ate the blazer and regular ball with zero issues. The buffer/spring did its job well, felt recoil was lighter than expected, cycling felt smoother than a standard setup, and like I said, functioned flawlessly with ammo that gun seemed to like. I’ll update this review whenever I throw in a super safety and run this build over 1k rounds. So far I’m quite happy with it.

5 of 5 9mm pcc buffer spring combo June 8, 2026
Reviewer: Russell Carter from Abingdon, VA United States  
My combo appears to be a solid unit. Well thought out and straight forward in design. Although I looks like a hydraulic unit it isn’t. I can’t wait until I find time to use it. I can’t see any reason for it not to do everything I need!

5 of 5 Fantastic Buffer June 8, 2026
Reviewer: Tanner from Saint George, UT United States  
Purchased this to go in my new AR9 build with an FRT. This worked flawlessly out of the box. No adjustments were needed. I slapped this bad boy in and it ran like a machine. Will be purchasing another for my next build.
