Gun Grease No. 9 1.75 oz is a must-have for anyone serious about the upkeep of their firearms. It’s not just another grease; it’s a top-tier solution to keep your shotgun running smoothly and protected from wear and tear. Whether you’re a seasoned shooter or a beginner, this product promises to keep your over under shotgun in top shape, no matter how much you use it.

Pros:

• Long-Lasting Lubrication: This gun grease does an excellent job of keeping the moving parts of your over under shotgun slick and efficient. It ensures smoother operation by reducing friction, which in turn, extends the life of your firearm.
   
• Superior Corrosion Protection: One of the standout features of Gun Grease No. 9 is its corrosion-resistant properties. This is crucial, especially if you often shoot in varying conditions or store your gun for long periods. Corrosion is one of the biggest enemies of any firearm, and this grease helps prevent that, keeping your shotgun in pristine condition.
   
• Easy to Apply: The 1.75 oz size is just right, and the grease comes in a convenient, easy-to-use container that ensures you don’t over-apply or waste product. Applying it on your over under shotgun becomes a breeze, ensuring that all necessary parts get the attention they need.
   
• Versatility: While it works wonders for your shotgun, it’s not limited to just one type of firearm. Gun Grease No. 9 is perfect for a variety of guns, which is great for someone who might own more than one firearm. This flexibility makes it a valuable addition to any shooter’s cleaning kit.
   

Cons:

• Not Ideal for Heavy Duty Use: While Gun Grease No. 9 does a fantastic job of lubricating and protecting against corrosion, it's not the best for extremely high-performance firearms or those exposed to heavy recoil or harsh environmental conditions. For certain hardcore users, something with more specialized properties might be necessary.
   
• Can Attract Dirt: As with many greases, it can attract dirt and debris over time. If you’re in a dusty environment, you may need to clean your shotgun more frequently to ensure that grime doesn’t build up and cause issues.
   
• Slightly Greasy Residue: While it provides fantastic lubrication, the greasy residue left after application can be a bit too much for some users. It may require a bit more wiping down, especially in areas where you don’t want excess grease to accumulate.
   

In conclusion, Gun Grease No. 9 1.75 oz offers a stellar balance of performance and protection, especially for over under shotguns. It keeps the moving parts in top form, preventing rust and wear while making maintenance as easy as possible.

But for the average shooter, this product is a fantastic choice to maintain your firearm’s longevity.

MIL-COMM TW25B Gun Grease Lubricant 1.5-Ounce Tube

MIL-COMM TW25B Gun Grease Lubricant is not your everyday firearm grease. It’s the kind of product that U.S. Special Forces trust with their weapons in harsh, demanding environments. Crafted for superior performance, this grease offers unmatched durability and ensures your over under shotgun is running like a well-oiled machine, whether you're hunting, shooting at the range, or in tactical situations.

Pros:

• Unrivaled Performance Under Extreme Conditions: TW25B is engineered to perform in temperatures ranging from -90°F to +450°F, making it the ideal choice for any weather. Whether you're out hunting in freezing temperatures or shooting in the blazing heat, this grease ensures smooth operation without failure. The protection it offers to your shotgun’s moving parts is second to none, making it perfect for over under shotguns exposed to extreme conditions.
   
• Superior Lubrication and Protection: Designed to lubricate while offering superior protection, MIL-COMM TW25B is the preferred choice for military-grade firearms. It prevents wear and tear on firearm components and protects against corrosion, all while reducing friction for smooth and reliable shots. This kind of reliability and protection is essential for any over under shotgun owner looking to get the most out of their firearm.
   
• Long-Lasting and Cost-Effective: TW25B isn't just durable—it’s also highly efficient. Live-fire trials have shown that you can fire 6 to 10 times more rounds between cleanings, using only a fraction of the lubricant compared to other products. This makes it one of the most cost-effective gun lubricants on the market, offering long-lasting protection without needing constant reapplication. For regular users, this makes maintenance easier and more affordable over time.
   
• Versatility Across Firearms: Whether you’re using AR’s, shotguns, handguns, or heavy weaponry, MIL-COMM TW25B is an excellent choice for various types of firearms. Its universal application makes it a one-stop solution for those who own multiple firearms, saving you the hassle of buying different lubricants for different weapons.
   

Cons:

• Thicker Consistency May Not Suit Everyone: While the thicker consistency of TW25B is great for long-lasting lubrication, some shooters may find it a bit challenging to apply, especially on smaller or more delicate firearm components. It can be a bit sticky for certain users, requiring a little extra effort to ensure an even application on over under shotguns.
   
• Slight Build-Up of Residue: Due to its thick nature, MIL-COMM TW25B can leave a residue if not applied correctly. While the grease excels at protecting your shotgun and reducing friction, it may require more frequent cleaning to ensure that no dirt or grime sticks to it, particularly for shooters who prefer a cleaner finish on their firearm.
   
• Not Ideal for High-Volume Cleanings: For those who engage in high-volume shooting or competitions, the extra layer of protection may lead to more frequent cleanings to avoid the build-up of grime. Though TW25B reduces the need for cleaning, it doesn’t eliminate it entirely, especially if you’re shooting hundreds of rounds in a short period.
   

In the world of gun lubricants, MIL-COMM TW25B stands out as a powerhouse designed to withstand the toughest conditions. Its ability to keep over under shotguns and other firearms functioning at their peak is unmatched. While it might not be the best fit for those who prefer a lighter, quicker application, its long-lasting effects and reliable protection make it a great investment for anyone serious about firearm maintenance.

Whether you're a recreational shooter or a professional who demands peak performance from your weapon, this synthetic light grease is engineered to significantly reduce friction and wear while offering unmatched durability, even in the harshest conditions.

Whether you’re firing hundreds of rounds or simply maintaining your over under shotgun, you can count on this grease to keep everything running smoothly.

No need to worry about rusting parts; EWG keeps them safe and operational.

This extreme temperature range is perfect for those who shoot year-round or engage in tactical situations where temperature fluctuations are common.
   
• No PTFE Ingredients: SLIP 2000 EWG is formulated without PTFE (Teflon), which means it doesn’t burn off like many petroleum-based lubricants. This is especially important for those who use their firearms frequently and want long-lasting performance without worrying about grease degradation. The absence of PTFE ensures the grease stays in place longer, offering continuous protection without the mess of burning-off lubricants.

Cons:

For those who don’t engage in high-volume shooting or don’t face extreme environmental conditions, the extreme pressure properties and long-lasting nature might be more than they need.
   
• Thick Consistency: While this thick consistency contributes to its durability, some shooters may find it slightly harder to apply, especially in tighter spots. You may need to spend a little extra time ensuring an even layer on all parts of your over under shotgun, particularly in the moving mechanisms.
   
• Price Point: Although SLIP 2000 EWG offers exceptional performance, it might be on the higher end of the pricing spectrum for some users. If you're on a tight budget, this may not be the most economical option compared to other lubricants on the market. However, considering the product’s longevity and effectiveness, many believe it’s a solid investment.
   

SLIP 2000 Extreme Weapons Grease (EWG) is an exceptional grease that delivers excellent lubrication, protection, and durability, particularly for over under shotguns.

If you're looking for an all-purpose gun grease that covers your entire firearm, you might need to complement this with a more robust lubricant for other parts of the gun.
   
• Requires Consistent Application: The effectiveness of the grease depends on regular use. If you forget to apply it before a session or neglect to reapply it after several rounds, you may find that your choke tubes can still become stuck or difficult to remove. While it’s easy to use, maintaining a routine application is key to its optimal performance.
   
• Can Leave a Residue: Some users might find that the lube leaves a slightly greasy residue on their hands or other parts of the firearm. While it’s not overwhelming, it might require a quick wipe-down to keep everything neat and clean, especially when applying it in a hurry or after several rounds of shooting.
   

Birchwood Casey Choke Tube Lube Grease offers excellent performance in preventing stuck choke tubes and protecting against corrosion, heat, and friction. Its easy application and heat resistance make it a perfect choice for over under shotgun owners who need a reliable solution to maintain their choke tubes.

• Reduced Friction and Wear: Slip2000 EWG is formulated to significantly reduce friction and wear on high-stress parts of your firearm, such as locking lugs, sears, bolts, and slides. This feature is critical for semi-auto and full-auto firearms, as these parts are subject to extreme pressures during repeated use.

Additionally, it’s an excellent choice for those shooting in confined spaces or for individuals with respiratory sensitivities.
   

Cons:

• Thicker Consistency: While the thick consistency of Slip2000 EWG provides great lubrication and long-lasting protection, it can be a little trickier to apply in tighter spots or small components. Some users may find that it takes a bit more effort to spread the grease evenly across delicate parts. However, with the included syringe applicator, this issue is somewhat mitigated, allowing for a more precise application.
   
• Not Suitable for All Temperatures: Although Slip2000 EWG performs well in high-pressure environments and against corrosion, it doesn’t quite hold up as well in extreme cold conditions. In freezing temperatures, the grease may stiffen, which could potentially interfere with the smooth operation of your over under shotgun. This makes it better suited for milder climates or for use in warmer months.
   
• Syringe Applicator Can Be Messy: While the syringe applicator is generally convenient for precise application, some users may find it a little difficult to control, especially when using it for larger tasks. Over-applying can lead to excess grease, which can be messy and require extra cleaning. It’s essential to apply just the right amount to avoid this issue, which might take a bit of practice.
