Our Ar-15, M16, M4, cleaning jag is made specifically for cleaning the Upper Receiver and Buffer Tube on these guns. It is made with pride in the USA. These patch jags press the patch that has been treated with solvent against the upper receiver or buffer tube to mechanically strip out debris that could inhibit your guns smooth functioning. These Jags are the only jag on the market designed to clean AR-15 Upper Receivers and Buffer Tubes. These patch jags work with the interrupted cuts in the AR-15 receiver and hold the patch during the scrubbing process. “The proof is on the patch”. In addition to cleaning, our jags are also used for lubricating the Upper Receiver. Our shotgun jags fit all standard rods with 5/16x27 threads. In addition to this product, we suggest you purchase and use Round TCS Patches for Shotguns. These patches are the perfect size for use with our jags and other patches may cause problems with tight fit. Square patches should not be used with our jags. Cleaning Jag Instructions
