Hoppe's HBL4 Black Precision Oil - 4 Oz Squeeze Bottle | Lubricates, Prevents Rust & Corrosion

The Hoppe's HBL4 Black Precision Oil is a 4-ounce squeeze bottle lubricant formulated to keep modern rifles—especially AR-15 platforms—running reliably in demanding conditions. AR shooters know their rifles prefer generous lubrication, and this is the right formula for the job. Whether you're putting rounds downrange in rapid succession or maintaining your rifle between trips to the field, Black Precision Oil is engineered to stay where you put it and keep doing its job.

What makes this oil stand out is its ability to withstand the intense heat generated inside a receiver during extended shooting. A lot of general-purpose gun oils thin out or evaporate when things get hot; this one is built to endure high-temperature environments and keep lubrication present even after a hard day at the range. The formula also incorporates rust-preventative chemistry, so you're protecting your investment against corrosion while you're protecting its performance.

The 4-ounce bottle is sized for serious shooters and maintenance kits. It comes with a precision-tip applicator, which makes it easy to get oil exactly where it needs to go—into tight spaces, onto bolt carriers, and into receiver channels—without overshooting or making a mess. Keep one in your range bag, your field kit, or your cleaning station.
