Mos 500 12G Optic Rail Mount Review

First Thoughts on the Mos 500 12G Optic Rail Mount

The Mos 500 12G Optic Rail Mount promises to enhance the versatility of one of the most popular shotguns in history, the Mossberg 500. For years, I’ve relied on my trusty Mossberg 500 for everything from upland bird hunting to home defense, appreciating its reliability and simple design. But I’ve always felt limited by the lack of easy optic mounting solutions, especially for red dots or weapon lights.

This led me to seek a practical, robust, and affordable way to add a Picatinny rail to my shotgun for mounting accessories. The market offers a variety of options, from complete forend replacements to receiver-mounted rails that require gunsmithing. However, I wanted a solution that was easy to install, didn’t require permanent modifications, and wouldn’t break the bank. Enter the Mos 500 12G Optic Rail Mount.

Upon unboxing, my initial impression was positive. The black finish appeared durable, and the machining looked clean for a product in this price range. It felt solid in hand, hinting at a robust design capable of withstanding the recoil of a 12-gauge. Compared to some of the bulkier, more expensive forend rail systems, the Mos 500 12G Optic Rail Mount appeared streamlined and unobtrusive, a definite plus.

I was choosing between this and a similar rail mount from ProMag, and a more elaborate forend from Magpul. I ultimately went with the Mos 500 12G Optic Rail Mount because it seemed like the best balance of functionality, ease of installation, and affordability. My first impression was cautiously optimistic; I was eager to see how it would perform at the range.

Real-World Testing: Putting Mos 500 12G Optic Rail Mount to the Test

First Use Experience

I tested the Mos 500 12G Optic Rail Mount at my local shooting range, focusing on evaluating its stability and how well it held zero with a mounted red dot sight. The weather was mild and dry, making for comfortable shooting conditions. Installation was surprisingly straightforward; it took less than five minutes using only a screwdriver. I primarily shot standard 2 ¾-inch birdshot and buckshot loads.

The mount held firmly in place throughout the initial 50 rounds. The red dot remained accurately sighted, showing no signs of shifting. Using the integrated sling stud with a tactical sling also proved comfortable and secure. There were no immediately apparent issues; the accessory felt like a natural extension of the shotgun.

Extended Use & Reliability

After several weeks and over 200 rounds of mixed birdshot, buckshot, and slug loads, the Mos 500 12G Optic Rail Mount has proven to be surprisingly durable. There are no signs of loosening or significant wear and tear. The black finish has held up well, with only minor scratches from handling. Cleaning is simple; a quick wipe-down with a lightly oiled cloth is all that’s needed.

Compared to other aftermarket shotgun accessories I’ve used, this mount has exceeded my expectations, particularly considering its price. I was initially concerned about its ability to withstand the constant recoil of a 12 gauge, but it has held up admirably. It definitely outperforms some of the cheaper, less robust options I’ve encountered.
