Sun Optics HK Scope Mount Review

Let’s Dive into Sun Optics HK Scope Mount

The Sun Optics HK Scope Mount is designed to provide a stable and reliable platform for mounting optics on Heckler & Koch firearms. Specifically, it is designed for the HK91, HK93, HK94, and MP5 platforms. Sun Optics aims to offer a cost-effective solution compared to some higher-end mounts on the market.

After acquiring an HK91 clone, I encountered the common issue of needing a suitable scope mount that wouldn’t break the bank. Many options available were either excessively expensive or plagued with negative feedback concerning their stability and build quality. This led me to the Sun Optics HK Scope Mount as a seemingly reasonable compromise between price and potential performance.

Upon unboxing, the mount felt surprisingly solid, especially considering its price point. The aircraft-grade aluminum construction gave it a decent heft, and the satin black finish appeared durable. It was clear that Sun Optics had prioritized functionality and affordability over high-end aesthetics.

Compared to some other options like B&T mounts (expensive!) and some cheaper, unknown brands (sketchy reviews!), the Sun Optics HK Scope Mount seemed to strike a decent balance. I ultimately chose it because of the positive (albeit limited) user feedback suggesting that it securely attached to the receiver, which was my primary concern. My initial impression was cautiously optimistic. I was hoping for a functional, no-frills mount that would hold zero, and I wasn’t expecting perfection at this price.

Real-World Testing: Putting Sun Optics HK Scope Mount to the Test

First Use Experience

My first test was at an outdoor shooting range in reasonably dry conditions. I mounted a Vortex Strike Eagle 1-6x scope onto the Sun Optics HK Scope Mount and attached the entire assembly to my Century Arms CA3 (a CETME-based HK91 clone). The initial mounting process was relatively straightforward using the included tools.

The first few shots revealed a solid connection with no noticeable movement of the mount on the receiver. However, I quickly realized that the cheek weld was less than ideal. Because the mount sits quite high, I had to adjust my shooting posture considerably to get a clear sight picture. Despite the initial awkwardness, the mount held zero through the first 50 rounds.

Extended Use & Reliability

After several months of regular use, the Sun Optics HK Scope Mount has proven to be reasonably reliable. It has remained securely attached to my HK91 clone, even after several hundred rounds of .308 Winchester. There is minimal evidence of wear and tear on the mount itself, although the satin black finish has shown a few minor scratches from handling.

Maintaining the mount is easy. I simply wipe it down with a lightly oiled cloth after each range session to prevent rust and corrosion. Compared to some other mounts I’ve used on different rifles, the Sun Optics HK Scope Mount performs adequately, especially when considering its price. It doesn’t offer the same level of refined precision as higher-end options, but it gets the job done for recreational shooting.

Performance & Functionality

The Sun Optics HK Scope Mount performs its primary function adequately: providing a stable platform for mounting optics. The mount maintains zero reasonably well under normal shooting conditions.

It meets expectations for a budget-friendly option. It doesn’t offer the bells and whistles of high-end mounts, but it functions reliably for recreational and range use.

The build quality is decent, with the aircraft-grade aluminum providing a solid feel. However, the 9 oz weight does add a noticeable amount of mass to the rifle. The user-friendliness is good. Installation is straightforward with the included tools, although some users might find the instructions a bit sparse.
