Otis Mission Critical Grease & Lubricant Review

The Otis Mission Critical Grease & Lubricant Made a Bold First Impression

In the demanding world of firearms maintenance, where reliability and longevity are paramount, the Otis Mission Critical Grease & Lubricant combo promises unwavering protection and performance. Otis, a trusted name in gun care, claims this unique blend of aerospace-industry lubricants can withstand extreme temperatures and prevent breakdown, making it a vital tool for any serious shooter. I was on the hunt for a lubrication system that could withstand the punishing conditions of high-volume shooting and varying climates, so I decided to give this product a try.

The Otis MC-10 arrived neatly packaged, the spray lubricant and grease applicator pen exuding a sense of quality. The sleek design and compact size were instantly appealing, promising convenient application and storage. I’ve previously used Hoppe’s No. 9 and Lucas Oil Extreme Duty Gun Grease, but the MC-10’s temperature resistance and promise of not carbonizing caught my eye, leading me to believe it could offer superior protection in extreme conditions. Initial impressions were positive, and I was eager to test Otis’s claims.

Real-World Testing: Putting Otis Mission Critical Grease & Lubricant to the Test

First Use Experience

I first tested the Otis Mission Critical Grease & Lubricant at an outdoor shooting range in the Nevada desert. Temperatures soared above 100 degrees Fahrenheit, presenting a perfect environment to challenge the MC-10’s high-temperature claims. I applied the lubricant to the slide and internal components of my AR-15, and the grease to the trigger assembly using the precision applicator pen. The gun felt noticeably smoother after the application.

Even after firing several hundred rounds, the action remained remarkably smooth, and I noticed minimal carbon buildup. The Otis MC-10 seemed to be performing as advertised, holding up remarkably well in the harsh desert conditions. The grease applicator pen allowed for precise application, avoiding any unnecessary mess.

Extended Use & Reliability

After several months of regular use and cleaning, the Otis MC-10 has proven to be a reliable and durable product. I’ve used it on a variety of firearms, including pistols, rifles, and shotguns, and it has consistently delivered excellent results. There’s been no noticeable wear or breakdown of the lubricant or grease, even after repeated exposure to high temperatures and harsh cleaning solvents. It continues to outperform my previous lubrication methods in terms of longevity and protection.

Maintaining firearms treated with the Otis MC-10 is also easier. Carbon fouling and debris wipe away with minimal effort, saving time and effort during cleaning. Compared to previous experiences with standard gun oils, which often require more frequent reapplication and cleaning, the Otis MC-10 delivers superior performance and peace of mind.

Breaking Down the Features of Otis Mission Critical Grease & Lubricant

Specifications

The Otis Mission Critical Grease & Lubricant combo includes a 1 fl. oz. spray bottle of high-performance synthetic lubricant and a 3mL precision applicator pen brush containing high-performance synthetic grease. This unique blend of aerospace-industry lubricants is formulated specifically for firearms, delivering unrelenting protection from -65 to 650 degrees Fahrenheit. The molecules are treated to hold to metal surfaces, unlike traditional lubricants.

• Temperature Resistance: The MC-10’s ability to function reliably from -65 to 650 degrees Fahrenheit ensures consistent performance in virtually any environment. This extreme temperature range is critical for maintaining firearm functionality in both frigid and scorching conditions.
• Synthetic Formula: The synthetic composition resists breakdown and carbonization, providing long-lasting protection and minimizing the need for frequent reapplication.
• Safe for All Surfaces: The MC-10 is safe to use on metals, plastics, rubbers, and woods, ensuring compatibility with a wide range of firearm components.
• Precision Applicator: The grease applicator pen allows for controlled and precise application in hard-to-reach areas like actions, triggers, and slides.
• Odor-Free: The absence of any noticeable odor makes it worry-free for indoor application.

Performance & Functionality

The Otis Mission Critical Grease & Lubricant excels in its primary function: protecting firearms from friction, wear, and corrosion. The lubricant provides a smooth and consistent action, improving the overall shooting experience. Reliability is consistently high, and firearms treated with MC-10 are less prone to malfunctions caused by friction or carbon buildup.

While the lubricant performs admirably, the grease applicator pen is a standout feature, allowing for precise application in critical areas. If there’s one area for minor improvement, it would be the spray nozzle on the lubricant bottle; a slightly finer mist could improve application consistency. Overall, the Otis MC-10 meets and exceeds expectations for a high-performance firearm lubricant.

Design & Ergonomics

Both the spray lubricant and grease applicator pen are designed with user convenience in mind. The spray bottle is compact and easy to handle, while the grease applicator pen offers excellent control over the amount and placement of the grease. The materials used are high-quality, ensuring durability and resistance to chemicals and solvents.

The applicator pen’s push-button mechanism allows you to meter grease with high precision; this is extremely valuable when you want to ensure the trigger and other action components receive the right amount of lubrication. There’s no steep learning curve associated with using the Otis MC-10. The application process is straightforward and intuitive, making it accessible to both experienced shooters and beginners.

Durability & Maintenance

The Otis Mission Critical Grease & Lubricant is designed for long-lasting performance and minimal maintenance. The synthetic formula resists breakdown, reducing the need for frequent reapplication. The treated molecules adhere strongly to metal surfaces, providing continuous protection even under extreme conditions.

Cleaning firearms treated with MC-10 is significantly easier. Carbon fouling and debris wipe away quickly, saving time and effort. Regular maintenance involves simply reapplying the lubricant and grease after cleaning, ensuring continued protection and smooth operation.

Accessories and Customization Options

The Otis Mission Critical Grease & Lubricant combo doesn’t require additional accessories for its intended purpose. However, it complements any standard firearm cleaning kit. It’s compatible with a wide range of firearms and accessories, making it a versatile addition to any shooter’s arsenal.
