Let’s Talk About Leupold 176887 Mark Integral Mounting System With 20MOA 1-Pc Base & 35mm Ring Co
The Leupold 176887 Mark Integral Mounting System With 20MOA 1-Pc Base & 35mm Ring Co is a purpose-built optic mounting solution for AR-style rifles. Designed and manufactured by Leupold, this system aims to eliminate common issues faced when mounting scopes on these platforms, specifically scope height and eye relief. This integrated system combines a one-piece base and 35mm rings, featuring a 20MOA elevation bias for extended-range shooting.
I was looking for a rock-solid mounting solution for my AR-10 build. I needed something that could withstand the recoil of the larger caliber and provide a stable platform for long-range shooting. The 20MOA cant was a key factor, as it would allow me to maximize the elevation adjustment in my scope when shooting at extended distances.
Upon unboxing, I was immediately impressed by the robust design and the quality of the aluminum construction. The finish was clean and even, and the overall feel was solid and confidence-inspiring. The weight felt appropriate, not too heavy as to be cumbersome, but substantial enough to suggest durability.
Compared to other options, like separate bases and rings from various manufacturers, the Leupold IMS system appealed to me because of its integrated design. It eliminates potential stacking tolerances and ensures perfect alignment between the base and rings. I also considered a Nightforce one-piece mount and an American Defense Manufacturing QD mount, but opted for the Leupold due to its reputation for reliability and the specific 20MOA cant that I required.
My first impression was overwhelmingly positive; this looked and felt like a premium mounting system built to perform. The simplicity of the design was also appealing, suggesting an easy and straightforward installation process. I was excited to get it mounted and head to the range.
Real-World Testing: Putting Leupold 176887 Mark Integral Mounting System With 20MOA 1-Pc Base & 35mm Ring Co to the Test
First Use Experience
My first test was at an outdoor shooting range known for its varied distances, up to 800 yards. I mounted the Leupold 176887 Mark Integral Mounting System on my AR-10, paired with a Leupold Mark 5HD 3.6-18×44 scope. Installation was remarkably easy, thanks to the one-piece design and clear instructions.
The system performed flawlessly in sunny conditions. The scope sat securely in the rings, and the 20MOA cant provided the extra elevation I needed to reach out to the longer distances. There was absolutely no movement or slippage, even after repeated firing of the .308 cartridge.
I did not need any time to adjust to the system; it was intuitive and performed exactly as expected. I was pleased with the initial zeroing process and the overall stability it provided for my optic.
Extended Use & Reliability
After several months of use, including multiple range trips and a precision rifle competition, the Leupold IMS system has proven its reliability. There are no signs of wear and tear beyond some minor cosmetic blemishes from handling. The finish has held up well despite exposure to the elements and regular cleaning.
Maintenance is minimal; I simply wipe down the system with a clean cloth after each use and occasionally check the torque on the mounting screws. Compared to previous setups with separate bases and rings, the Leupold IMS system has significantly outperformed them in terms of stability and ease of maintenance. It provides a consistent and reliable platform for my optic, enabling me to focus on my shooting.
