First Impressions of XTS Polymer Rear Flip-Up Sight
The XTS Polymer Rear Flip-Up Sight promises a lightweight and budget-friendly aiming solution for AR-15 platforms. Manufactured by XTS, this sight aims to provide a reliable backup or primary sighting option without breaking the bank. I was keen to test if this polymer sight could hold its own against more expensive metal alternatives.
My interest in the XTS Polymer Rear Flip-Up Sight stemmed from a desire for a lightweight backup sight for my AR-15. I had recently built a lightweight AR for backpacking trips, and every ounce mattered. I needed a durable, functional, and affordable rear sight that wouldn’t add significant weight to my rifle.
Upon unboxing, the sight felt surprisingly solid for being polymer. The finish was clean, and the flip-up mechanism operated smoothly with a positive lock in both the up and down positions. Compared to a Magpul MBUS, the XTS sight felt slightly less refined, but the price difference was significant.
I considered the Troy Industries folding sight and the Diamondhead USA metal sight, but both were substantially more expensive. The XTS Polymer Rear Flip-Up Sight seemed like a reasonable compromise, offering essential functionality at a fraction of the cost. My initial impression was cautiously optimistic; it appeared well-made for the price.
Real-World Testing: Putting XTS Polymer Rear Flip-Up Sight to the Test
First Use Experience
I first tested the XTS Polymer Rear Flip-Up Sight at my local outdoor shooting range. The weather was dry, with temperatures in the mid-70s. I mounted the sight on my AR-15’s Picatinny rail and zeroed it at 50 yards.
Zeroing was straightforward, thanks to the easily adjustable windage knob. The aperture provided a clear sight picture, and the flip-up mechanism worked reliably. After about 100 rounds, the sight held zero without issue.
However, after repeated use, I noticed the polymer construction did get warmer than a metallic sight. This was particularly noticeable when shooting rapid fire drills. Despite this, the XTS Polymer Rear Flip-Up Sight performed adequately.
Extended Use & Reliability
After several months of use, the XTS Polymer Rear Flip-Up Sight has held up surprisingly well. I’ve used it in various conditions, including a dusty desert environment and during a light rain. There are a few minor scuff marks on the polymer, but the sight remains fully functional.
The flip-up mechanism is still smooth, and the windage adjustment remains positive and secure. Cleaning the sight is easy; a quick wipe down with a cloth removes most dirt and debris. Compared to the metal backup sights I’ve used previously, the XTS sight requires slightly more care to avoid scratching the polymer, but the weight savings is worth it.
