First Impressions of Luth-AR A2 Rear Sight Kit
The Luth-AR A2 Rear Sight Kit promises to be a complete solution for those looking to complete or replace the rear sight assembly on a Mil-Spec A2 upper receiver. As someone who appreciates the simplicity and ruggedness of the A2 platform, I was eager to see if this kit lived up to Luth-AR‘s reputation for quality components. This kit is designed for AR-15 rifles utilizing the classic A2-style fixed carry handle upper receiver, providing both elevation and windage adjustments.
I had an A2 upper receiver sitting in my parts bin for a while now, stripped of its rear sight assembly. I was keen to bring it back to its original configuration. Finding a complete, reliable kit seemed like the best way to get it done correctly and efficiently.
The kit arrived well-packaged, with all the components neatly organized. My initial impression was positive. The parts felt solid and well-machined. Comparing it to similar kits from other manufacturers, the Luth-AR A2 Rear Sight Kit seemed to offer a better balance of price and perceived quality.
My first impression was excitement mixed with a little apprehension about the assembly process, given the small parts involved. However, I was confident that with patience and the right tools, I could bring my A2 upper back to life. The overall quality and completeness of the kit made me optimistic.
Real-World Testing: Putting Luth-AR A2 Rear Sight Kit to the Test
First Use Experience
My initial testing took place at my local outdoor shooting range, under relatively clear conditions. I installed the Luth-AR A2 Rear Sight Kit onto my previously mentioned stripped A2 upper and mounted it on my go-to AR-15 lower. I wanted to zero the rifle at 50 yards, using standard M193 5.56 ammunition.
The sight adjustments were smooth and consistent, although I quickly learned the importance of making small adjustments, as each click moved the point of impact more than I initially expected. I had no issues with the sight picture, even in the bright sunlight, and found the aperture size to be adequate for both close- and medium-range targets. After a few minor tweaks, I got zeroed in quickly.
The only issue I encountered was a slight loosening of the windage knob after about 50 rounds. However, tightening it resolved the problem. The only surprise was how much I enjoyed using the A2 sight again after years of using optics.
Extended Use & Reliability
After several range trips spanning a few months, the Luth-AR A2 Rear Sight Kit has proven to be reliable. I’ve put several hundred rounds through the rifle with this sight installed. It remains securely mounted and maintains its zero well.
There are no noticeable signs of wear and tear, even after exposure to heat and some mild rain. I simply wipe down the sight with a lightly oiled cloth after each range session. This keeps it clean and prevents any corrosion.
Compared to a budget-friendly rear sight I used years ago, the Luth-AR is significantly more robust and holds its adjustments far better. I’m impressed with the overall durability and reliability of this kit. It has exceeded my initial expectations.
