Burris FastFire 3 Red Dot Sight – Lightweight Reflex Optic

🎯 Burris FastFire 3 Red dot – Fast, Simple, Proven Performance

The Burris FastFire 3 Red Dot is a proven reflex optic. Also trusted by shooters who want speed without complexity. Designed for pistols, shotguns, and lightweight rifles, it delivers a crisp aiming point, large viewing window, and ultra-lightweight profile that won’t slow you down or compromise balance.

Available in 3 MOA or 8 MOA dot options, the FastFire 3 lets you choose between precision-focused accuracy or lightning-fast acquisition for close-range engagements. The simple, intuitive controls make brightness adjustments quick and easy, even under stress.

🛡️ Burris FastFire 3 Red dot – Built for Real-World Use

The FastFire 3 features a rugged aluminum housing engineered to hold zero under recoil while remaining light enough for slide-mounted pistol use. Its design has been field-proven across thousands of duty, competition, and recreational firearms.

An automatic brightness sensor adjusts the reticle based on ambient light, while manual brightness settings allow shooters to override for personal preference or specific lighting conditions.

🔧 Burris FastFire 3 Red – Flexible Mounting Across Platforms

Using the Docter / Noblex footprint, the FastFire 3 mounts easily to a wide range of adapter plates and optic-ready firearms. A Picatinny rail mount is included, allowing fast installation on carbines, shotguns, or offset mounts right out of the box.

⚠️ Mounting Notice:
The Burris FastFire 3 uses the Docter / Noblex footprint. It is not directly compatible with RMR or RMSc slide cuts without an adapter plate.

🔋 Long Battery Life, Minimal Maintenance

Powered by a CR1632 battery, the FastFire 3 offers up to 5 years of battery life depending on brightness settings. The top-mounted battery compartment allows quick changes without removing the optic or re-zeroing — a major advantage over bottom-mounted designs.
