Lockstep Arms Billet MOS Optic Plate Cover Review

First Impressions of Lockstep Arms Billet MOS Optic Plate Cover

The Lockstep Arms Billet MOS Optic Plate Cover is a seemingly simple component that addresses a common aesthetic and practical concern for pistol owners who utilize Modular Optic System (MOS) slides. Lockstep Arms aims to provide a sleek, durable solution to fill the void left when an optic isn’t mounted. This little plate promises to protect the slide’s internals and offer a cleaner look than an exposed MOS cut.

I recently acquired a new Glock 19 MOS, and while I plan to mount an optic eventually, I wanted a temporary solution to protect the slide and keep debris out while I researched optic options. The exposed cut bothered me visually, and I was concerned about long-term wear and tear. The Lockstep Arms Billet MOS Optic Plate Cover appeared to be the perfect fix.

Upon unboxing, I was immediately impressed by the clean machining and the deep black anodized finish. It felt substantial despite its small size, suggesting a robust build quality. Compared to the polymer plates that sometimes come with MOS-cut slides, this Lockstep Arms cover felt like a significant upgrade, both in terms of aesthetics and durability. I chose this over cheaper, generic covers because of Lockstep Arms’s reputation for precision and quality.

My first impression was overwhelmingly positive. The Lockstep Arms Billet MOS Optic Plate Cover seemed to be exactly what I needed: a well-made, aesthetically pleasing solution to a minor but persistent annoyance. It seemed more refined than other options. I was excited to install it and see how it held up to real-world use.

Real-World Testing: Putting Lockstep Arms Billet MOS Optic Plate Cover to the Test

First Use Experience

I installed the Lockstep Arms Billet MOS Optic Plate Cover on my Glock 19 MOS slide in about a minute using the factory screws. The fit was snug and precise, with no noticeable gaps or movement. I took the pistol to my local shooting range for a function test, putting about 200 rounds downrange.

During the range session, the plate remained securely in place. It showed no signs of loosening or shifting, even with the repeated recoil. The black anodized finish also held up well, resisting scratches and marks from ejected brass. While the plate doesn’t directly impact shooting performance, I appreciated the peace of mind knowing my slide was protected from debris.

Extended Use & Reliability

After several months of regular use, including weekly trips to the range and daily carry, the Lockstep Arms Billet MOS Optic Plate Cover continues to perform flawlessly. There are no signs of wear and tear on the plate itself. The black anodizing is still pristine.

Maintenance is virtually nonexistent; I simply wipe it down with a cloth when I clean the pistol. Compared to the factory polymer plate, which showed wear marks and slight deformation after only a few range sessions, the Lockstep Arms cover is a clear winner in terms of durability. It exceeds my expectations, proving to be a reliable and long-lasting solution.
