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

My first impression of Burris FastFire 3 1x 21x15mm 3 MOA Red Dot Sight

For years, I’ve been a staunch advocate of iron sights, clinging to the belief that simplicity equates to reliability. But the world of optics moves fast, and the Burris FastFire 3 1x 21x15mm 3 MOA Red Dot Sight kept popping up in conversations with colleagues and at the range, piquing my curiosity. The Burris name carries weight in the optics world, and the promise of improved target acquisition and faster follow-up shots was tempting enough for me to give it a try.

I was looking for a compact, durable red dot sight that wouldn’t break the bank. I needed something reliable enough to withstand the recoil of my pistol and the rough handling it often endures during training. Upon unboxing, the FastFire 3 immediately impressed me with its solid steel construction and surprisingly lightweight design. The matte black finish looked clean and professional, and the included picatinny mount felt sturdy and well-made.

I considered the Trijicon RMR and the Aimpoint Micro T-2, both legendary red dots, but their price points were significantly higher. The Burris FastFire 3 seemed to offer a compelling balance of quality and affordability. My first impression was one of cautious optimism; could this relatively inexpensive optic truly hold its own against the giants in the industry?

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

First Use Experience

My initial testing ground was the local shooting range, where I mounted the Burris FastFire 3 on my Smith & Wesson M&P 9mm. I wanted to assess its performance under controlled conditions before subjecting it to more demanding scenarios. Zeroing was surprisingly simple, with the upgraded windage and elevation adjustments providing tactile clicks and consistent movement.

I shot several hundred rounds that first day, focusing on rapid target acquisition and transitions. The 3 MOA dot proved to be an excellent compromise, offering precision for longer shots while remaining visible enough for quick close-quarters engagements. The automatic brightness setting adapted seamlessly to the changing light conditions inside the range, which made for quick transitions between the target and the surrounding environment.

Extended Use & Reliability

After several months of consistent use, the Burris FastFire 3 has proven to be remarkably robust. I’ve taken it through several pistol courses in varying weather conditions. Even after being exposed to rain and dust, the optic continued to perform flawlessly.

I’ve noticed minimal wear and tear on the steel body, which speaks volumes about its construction quality. Cleaning the lens is straightforward, requiring only a soft cloth and occasional wipe-down. I’ve used other optics that require constant adjustments and battery replacements, but the FastFire 3 has been a refreshing change of pace. It simply works.
