Best Gun Oil for the AR-15 Rifle

Is there a best gun oil for the AR-15 rifle?

I think so. The AR-15 rifle has fairly tight tolerance and so you need a thinner oil that can get into and stay in tight places. I have had 2 AR-15’s (Stag Arms T2 and Smith & Wesson M&P 15) and tried many gun oils on them. Both of these rifles were 100% reliable with zero failures regardless of lubricant.

So what gun oil did I like and use? I first used BreakFree CLP for about a year and then switched to Hoppe’s No 9 Synthetic Blend Lubricating Oil. The reason I switched was not because BreakFree CLP failed but because I physically tested the 2 lubricants with 2 pieces of metal and the Hoppe’s No 9 Synthetic Blend gun oil felt a lot more slipperier. Synthetic oils reduce friction and wear more than conventional oils.

I want to say one more thing about firearm lubrication and that is that most gun oils are better than CLP’s at lubrication and synthetic oils are better than traditional petroleum oils. If you’re looking for a dry lubricant, Hornady One Shot is excellent. It is extremely slippery and easy to apply.
