Fightlite Industries Mcr H3 Buffer
The Fightlite Industries MCR H3 Buffer is a specialized component designed for MCR (Modular Carbine Rifle) platform full-auto weapons. If you're running a select-fire MCR setup, bolt bounce—that unwanted recoil-driven movement of the bolt carrier—can degrade accuracy and accelerate wear on critical components. This buffer is engineered to control that action and keep your cycling consistent, which matters when precision and reliability are both on the line.
Built for a specific platform and use case, the H3 is the right choice if your MCR is configured for full-auto fire. It works within the MCR's recoil system to dampen and stabilize bolt carrier movement, helping maintain shot grouping and reduce the mechanical stress that comes with rapid cycling.
Whether you're at a registered range, a professional training facility, or a private property where you're legally running a full-auto MCR, this buffer ensures your platform performs as intended. It's a straightforward upgrade that addresses a real problem in high-round-count or full-auto shooting.

Frequently Asked Questions
Is this buffer compatible with semi-auto MCR rifles?
This buffer is designed specifically for MCR full-auto weapons. Compatibility with semi-auto MCR platforms should be verified with Fightlite Industries or your gunsmith before installation.
What does bolt bounce mean, and why should I care?
Bolt bounce is the uncontrolled rearward movement of the bolt carrier after firing, caused by recoil. It can reduce accuracy and increase wear on your action. The MCR H3 Buffer is engineered to control and dampen that movement, keeping your cycling smooth and your shots consistent.
Do I need tools to install this buffer?
Installation details are not provided in our materials. Consult the Fightlite Industries documentation or a qualified gunsmith for proper installation procedure.
