Remington Oil

If you're looking to maintain your AR15, I'd recommend giving Remington Oil a try on AR15 bolt carrier group that experiences lot of friction. Despite some mixed reviews, it's a reliable choice for keeping your firearm in top condition to reduce friction and protect against corrosion.

Remember, it's important to apply it correctly: just a thin layer, and then wipe off any excess. This method ensures that Rem Oil performs at its best.

Plus, its Teflon content adds an extra layer of protection, making it a solid choice for regular gun care. Don't let a few negative reviews sway you; Remington Oil has proven its worth in many gun owners' arsenals without complicating things.

If you're looking to clean your AR15 internals without fuss or needing deep chemical knowledge, I highly recommend Ballistol oil. It's an incredibly user-friendly cleaner. It's non CFC aerosol lubricant made specifically for firearm parts.

Just apply it, let it soak for a bit, and scrub. The dirt and carbon come off easily. It's safe for various materials and leaves a protective coating that guards against rust. Plus, it has a pleasant scent, making the cleaning process more enjoyable. 

The most important thing is that it doesn't smell as strong as Hoppe's No. 9 cleaning oil.

If you're looking to lubricate your AR-15 after a deep clean, I highly recommend Frog Lube paste. Its unique formula works exceptionally well on warmed-up metal parts, ensuring deep penetration and thorough cleaning. 

The paste is easy to apply and leaves your gun parts impressively clean and protected. Plus, its pleasant minty scent is a refreshing change from harsh chemical odors.

Frog Lube not only cleans but also lubricates and protects against rust, making it an all-in-one solution for firearm maintenance. Safe and non-toxic, it's an ideal choice for keeping your AR-15 in top condition.

When firing the rifle, heat will warm up the paste and lubricate any moving parts automatically. I highly recommend placing some around the bolt carrier group and the bolt head.

Gun Oil FAQ

How Much Gun Oil Should I Use?

Lubrication is vital for the longevity and reliability of your weapon. So, keep it well-lubricated to ensure it performs at its best when you need it most.

Whether you use a little or a lot of lube, there's always a chance of attracting some debris. However, the key lies in regular maintenance. Each time you use your gun, especially for intensive training sessions or missions, it's essential to clean and maintain it afterward.

This practice is particularly important for law enforcement officers and citizens who might not encounter extreme conditions regularly but still need their firearms to function reliably.

What's The Difference Between Gun Oil and CLP?

Many shooters appreciate CLP for its ability to resist fouling build-up better than some gun oils, making it an excellent choice for a quick clean and lubrication session.

Lubricants are generally more suitable for immediate, on-the-spot lubrication needs, whereas CLPs are great as comprehensive, all-in-one solutions, especially when you have the time to disassemble and properly apply them to your firearm.

However, it's important to consider the temperature sensitivity of both gun oil and CLP. Each product is formulated to perform optimally within a certain temperature range. Using them outside these specified conditions can lead to the lubricant gumming up, which can cause significant issues with firearm performance.
