Trijicon MRO Slip on Cover Clear w/Clear Lens Review

Meet the Trijicon MRO Slip on Cover Clear w/Clear Lens: First Thoughts

My quest for an effective and unobtrusive lens protection solution for my Trijicon MRO red dot sight led me to the Trijicon MRO Slip on Cover Clear w/Clear Lens. I’d recently acquired the MRO for a new build and, having spent years in environments where delicate optics can meet untimely ends, I knew protection was paramount. The thought of rain, dust, or a careless brush knocking against the lenses while out in the field or even just on the bench, was a persistent nagging worry. While many red dot sights offer integrated flip-up caps, the MRO’s design, with its unique shape, seemed to demand something a bit more tailored. After a quick look around, generic lens covers seemed unlikely to fit securely or provide the robust protection I desired.

The immediate impression upon receiving the Trijicon MRO Slip on Cover Clear w/Clear Lens was one of quality, albeit a bit of a puzzle to figure out how it all came together. The cover itself felt like a substantial, yet flexible, piece of molded rubber or a similar durable polymer. The clear lens caps, which are a key selling point, appeared surprisingly robust, not flimsy or prone to immediate scratching. I’d briefly considered the more generic elastic band-style covers, but their tendency to shift or detach under stress made them a non-starter for my intended use. This Trijicon offering, with its “slip-on” design, promised a more integrated and secure fit, a concept that immediately appealed to my desire for a clean, functional setup. My initial feeling was a sense of cautious optimism, hoping this accessory would live up to the Trijicon reputation.

Real-World Testing: Putting Trijicon MRO Slip on Cover Clear w/Clear Lens to the Test

First Use Experience

My primary testing ground for this optic accessory was a mix of range days and general handling while setting up and moving various equipment. I took the Trijicon MRO, now fitted with its new cover, to the local outdoor range. The day presented a light drizzle and a persistent breeze carrying fine dust from the unpaved firing line. Later, I moved it to my workbench, where it sat alongside other tools and components, a prime candidate for accidental bumps and scrapes.

The performance in these initial conditions was quite telling. The cover itself provided a good barrier against the light rain, and the clear lens caps allowed for immediate use without needing to remove anything. The dust, while present, was easily wiped from the cover and lenses. The real test of ease of use came during the installation process, which, as noted by others, was a bit of a struggle. Once on, however, the cover felt incredibly secure, and I was able to shoulder the rifle and acquire targets without any sense of the cover shifting or impeding my view. There were no immediate issues, though the initial application definitely required more effort than I anticipated.

Extended Use & Reliability

After several months of consistent use, including being packed and unpacked, transported in gear bags, and subjected to various environmental conditions, the Trijicon MRO Slip on Cover Clear w/Clear Lens has proven to be remarkably resilient. It’s been exposed to dusty workshops, the occasional damp morning hike (carried disassembled in a pack), and countless hours on the range. The durable thermoplastic polyurethane material has held up exceptionally well, showing only minor scuffs that are barely noticeable against the matte finish of the cover itself. It has resisted oils and solvents encountered in my workshop without any degradation.

Maintenance has been straightforward: a quick wipe with a damp cloth or a brush usually suffices to remove dust and debris. The cover has maintained its snug fit, showing no signs of stretching or loosening. When compared to the generic elastic covers I’ve used in the past, which often become baggy and lose their elasticity quickly, this Trijicon accessory feels like it’s built to last. The initial difficulty in installation now feels like a testament to its long-term reliability and secure fit; it’s a trade-off I’m more than willing to accept for the peace of mind it provides.

Breaking Down the Features of Trijicon MRO Slip on Cover Clear w/Clear Lens

Specifications

The Trijicon MRO Slip on Cover Clear w/Clear Lens is designed specifically for the Trijicon MRO reflex sight, offering a protective sheath for both the optic’s body and its lenses. The primary material is a durable thermoplastic polyurethane, a material known for its excellent resistance to abrasion, oils, solvents, and UV exposure, ensuring longevity even in harsh conditions. The integral lens covers are made from a clear, impact-resistant polymer, allowing for immediate use of the optic without removal.

These covers are designed for one-handed operation, a crucial feature for quick deployment in dynamic situations. The low-profile design ensures they don’t add significant bulk or snag on gear. A key engineering aspect is how the covers nest together, preventing them from flopping around or creating noise under recoil. This attention to detail, combined with the ability for the material to accept most spray paints and hydro dip processes, offers a level of customization and adaptability that is often overlooked in such accessories.

Performance & Functionality

The core function of this optic cover is to protect the Trijicon MRO’s lenses and body from the elements and physical damage, and it performs this role admirably. The clear lens covers are a standout feature; they provide a level of protection that is almost always ready to go, eliminating the need for fumbling with separate caps when seconds count. I’ve found them to be surprisingly resilient against minor scratches, and they don’t seem to introduce any noticeable distortion or color shift that would hinder aiming.

The primary strength of this slip-on cover is its secure, form-fitting design. Once installed, it feels like a natural extension of the optic rather than an add-on. Its weakness, if it can be called that, is the initial installation, which requires significant effort to stretch the polymer over the sight. This is a deliberate design choice to ensure an extremely tight fit, but it can be intimidating the first time. Ultimately, it exceeds expectations for its intended purpose, offering robust protection without compromising immediate usability thanks to those clear lens caps.

Design & Ergonomics

The design of the Trijicon MRO Slip on Cover Clear w/Clear Lens is a testament to thoughtful engineering focused on practicality and durability. The thermoplastic polyurethane material has a slightly textured finish that provides a good grip, even with gloved hands or when they’re a bit sweaty. The overall shape follows the contours of the MRO precisely, creating a sleek profile that doesn’t snag on clothing, gear, or vegetation.

Ergonomically, the most significant aspect is the functionality of the integrated lens covers. They can be flipped open with a single finger, and the way they nest together is a clever solution to a common problem. There is a slight learning curve to mastering the one-handed operation, especially when trying to do it quickly under pressure, but consistent practice makes it intuitive. The tight fit, while a challenge to put on, makes the entire assembly feel cohesive and solid once it’s in place.

Durability & Maintenance

In terms of durability, this Trijicon accessory feels built to withstand significant abuse. The thermoplastic polyurethane material is inherently tough and resistant to damage from impacts, abrasions, and chemicals. I haven’t observed any signs of cracking, tearing, or premature wear, even after repeated flexing during installation and operation.

Maintenance is refreshingly simple. A quick rinse under water or a wipe down with a damp cloth is usually sufficient to keep it clean. For more stubborn dirt or grime, a mild soap can be used, followed by a thorough rinse. The material is non-porous, so it doesn’t absorb stains or odors. I have not experienced any issues that would indicate potential failure points. The design itself is simple – a single piece of molded material with integrated covers – which inherently reduces the likelihood of mechanical failure compared to designs with multiple moving parts.

Accessories and Customization Options

The Trijicon MRO Slip on Cover Clear w/Clear Lens comes as a complete unit, with the integral clear lens covers being its primary feature beyond the protective body. There are no additional accessories included, as this item is designed to be a direct, all-in-one solution for MRO lens protection. However, a noteworthy feature for those who like to personalize their gear is that the cover’s material is receptive to most spray paints and hydro dip processes.

This allows users to camouflage the cover to match their rifle or environment, or simply to give it a custom aesthetic. For users who prefer a different aesthetic or functional approach, the MRO itself has a wide array of mounting solutions, but this particular cover is designed to integrate seamlessly with the optic’s form factor, making it difficult to pair with many aftermarket modifications that might alter the optic’s body shape.

Pros and Cons of Trijicon MRO Slip on Cover Clear w/Clear Lens

This optic cover is ideal for any Trijicon MRO owner who values robust protection for their sight, especially those who operate in challenging environments. It’s perfect for individuals who frequently encounter dust, rain, snow, or potential impacts, such as competitive shooters, tactical operators, hunters, or even those who simply want to safeguard their investment during transport and storage. The clear lens covers make it an excellent choice for users who need to be ready to engage targets instantly without any preparation time.

Those who should consider alternatives might include individuals who prioritize the absolute fastest lens deployment mechanism possible, or those who are apprehensive about the forceful installation process.
