Let’s Dive into Troy Dioptic Apeture DOA Top Mounted Deployable Rear Sight
The Troy Dioptic Apeture DOA Top Mounted Deployable Rear Sight is a combat-ready sighting solution from Troy Industries, designed for rapid target acquisition and enhanced accuracy. Featuring a di-optic aperture system with settings for both 300 and 500 meters, this rear sight is aimed at military, law enforcement, and home defense users who demand reliable performance under pressure.
My journey to this sight started with a frustrating experience at a recent carbine course. I was struggling with quick target acquisition using standard iron sights, particularly under stress. I needed a backup sighting system that was faster and more intuitive than my existing setup, leading me to explore options like the Troy Dioptic Apeture DOA Top Mounted Deployable Rear Sight.
The Troy sight arrived in a no-frills package, immediately showcasing its robust construction. The anodized aluminum felt solid and lightweight. Deploying the sight was smooth and positive, and the di-optic aperture was noticeably different than traditional round apertures.
Compared to standard A2-style rear sights, the Troy DOA offered a more refined and arguably faster sighting method. I also considered Magpul’s MBUS Pro, but the Troy‘s reputation for durability and the unique aperture design ultimately swayed my decision. The Troy Dioptic Apeture DOA Top Mounted Deployable Rear Sight promised faster target acquisition and greater accuracy, especially at varying distances.
My initial impression was one of cautious optimism. While the build quality was impressive, the di-optic aperture was an unknown quantity. Would it truly improve my shooting, or would it be a gimmick? Only real-world testing would tell.
Real-World Testing: Putting Troy Dioptic Apeture DOA Top Mounted Deployable Rear Sight to the Test
First Use Experience
My first outing with the Troy Dioptic Apeture DOA Top Mounted Deployable Rear Sight was at an outdoor shooting range, under typical sunny conditions. I mounted the sight on my AR-15, pairing it with a standard A2 front sight post. I tested it at distances ranging from 25 to 100 yards.
The di-optic aperture initially took some getting used to. I found that focusing on the front sight post was even more critical than with standard apertures. However, once I adjusted, target acquisition became significantly faster, especially when transitioning between targets. There were no operational issues, the sight deployed and locked positively every time, and adjustments were crisp and predictable.
Extended Use & Reliability
After several months of regular use, the Troy Dioptic Apeture DOA Top Mounted Deployable Rear Sight has proven to be remarkably durable. I’ve put several hundred rounds downrange with it, and it shows no signs of wear or loosening. The finish has held up well against scratches and dings.
Maintenance is simple. A quick wipe-down with a lightly oiled cloth after each range session is all it needs. It’s exceeded my expectations in terms of robustness, proving to be a reliable backup sighting system that I can trust in any situation. It definitely outperforms the basic A2 sights I’d used before.
