Optimus Modular Weight Buffer

Unleash the full potential of your AR platform with the Strike Industries Optimus Modular Weight Buffer. Developed for performance-driven shooters, this innovative buffer system allows for rapid, user-customizable weight adjustment to maximize reliability, accuracy, and overall shooting performance.

The Optimus Weight Buffer arrives pre-configured with standard H1-H3 weights but can be quickly tailored to your exact needs. The durable 7075 aluminum outer body securely houses the modular weight stack, utilizing specialized rubber spacers to reduce internal recoil impact and protect the components.

An integrated O-ring prevents buffer head walkout, while the optimized size and mass distribution promote smooth, consistent cycling. Whether running different calibers, gas systems suppressed, or rapid-fire scenarios, the Optimus Buffer’s wide range of user-configurable weights ensures a perfectly tuned recoil impulse.

Upgrade to the ultimate shooting experience with the Strike Industries Optimus Modular Weight Buffer.
