Burris FastFire 3 1x 21x15mm 3 MOA Black Red Dot Sight Review

The Burris FastFire 3 1x 21x15mm 3 MOA Black Red Dot Sight Made a Bold First Impression

For over a decade, I’ve relied on iron sights and magnified optics, but lately, I’ve been increasingly drawn to the speed and simplicity of red dot sights, especially for close-quarters scenarios. The Burris FastFire 3 1x 21x15mm 3 MOA Black Red Dot Sight piqued my interest with its compact size, reputation for durability, and ease of use – features that seemed perfect for my AR-15 pistol build. After hearing from other specialists how useful and versatile they are, it became apparent I needed to test one for myself.

I’d grown tired of the bulkiness of some larger optics. Also, I wanted something quicker to acquire targets with in dynamic shooting situations. The Burris FastFire 3 promised both, so I decided to give it a shot.

The unboxing experience was straightforward, with the sight, a Picatinny mount, a protective cap, and necessary tools neatly packaged. My first impression was positive, noting its surprisingly lightweight construction and seemingly rugged build quality, despite its small size. It felt solid in my hand.

I considered the Trijicon RMR and Aimpoint Micro T-2 before settling on the FastFire 3. While those are top-tier options, the Burris offering presented a more budget-friendly alternative without sacrificing essential performance features. I was also drawn to the top-mounted battery compartment, which seemed far more practical than the RMR’s under-mounted design. I was excited to see how this optic would improve my close-quarters performance.

Real-World Testing: Putting Burris FastFire 3 1x 21x15mm 3 MOA Black Red Dot Sight to the Test

First Use Experience

My initial testing took place at an outdoor shooting range, mounting the FastFire 3 on my AR-15 pistol. The weather was typical for the region – sunny with a slight breeze. Zeroing was surprisingly easy, with the tool-less windage and elevation adjustments making the process quick and painless.

The 3 MOA dot was crisp and clear, even in bright sunlight, and target acquisition was noticeably faster than with iron sights. I ran several drills, focusing on rapid transitions between targets at varying distances, and the FastFire 3 performed admirably. After a few adjustments, I was hitting bullseyes consistently at 25 yards.

There were no immediate issues. The sight held zero well, and the automatic brightness setting seemed to adjust appropriately to changing light conditions. My initial impression was definitely positive.

Extended Use & Reliability

After several months of regular use, the Burris FastFire 3 has proven to be a reliable and durable optic. I’ve taken it through multiple range sessions, a weekend-long tactical training course in moderately dusty conditions, and even a brief stint mounted on my shotgun during a turkey hunt. It has consistently held zero and maintained its performance.

While the finish shows some minor signs of wear from rubbing against gear, there are no significant scratches or damage. The battery life has been impressive, and I haven’t needed to replace it yet. Cleaning is simple, requiring only a lens cloth to remove any dust or debris. The sight remains clear and functional.

Having used other budget-friendly red dots in the past that quickly fell apart, the FastFire 3 has exceeded my expectations in terms of durability and reliability. It’s proven to be a worthy addition to my setup. I can happily and confidently say it has outperformed some of the more expensive optics I’ve owned.
