CMMG H3 Buffer Assembly
The H3 buffer represents the heaviest option in the carbine buffer lineup, engineered for shooters seeking maximum recoil reduction and improved reliability.
Key Features
- Weight: 5.4 ounces—the heaviest carbine buffer available
- Purpose: Reduces felt recoil and corrects erratic case ejection patterns
- Quality: Backed by CMMG's Lifetime Quality Guarantee
Performance Considerations
Heavier buffers work by increasing the mass in your bolt carrier group, which slows the cycling rate of your rifle. This can provide noticeable benefits:
- Reduced recoil impulse for more comfortable shooting
- Improved case ejection consistency
- Better reliability with certain ammunition or suppressor setups
Installation Guidance
When tuning your AR15, approach buffer weight changes incrementally. Start with a standard buffer and work up to heavier options as needed. A buffer that's too heavy can negatively affect function, so find the balance that works best for your specific rifle configuration and ammunition.
The H3 is an excellent choice for shooters running suppressors, shooting high-volume practice sessions, or simply seeking a softer shooting experience.
