Tetra oil
have used tetra oil for many years. not on the hunting weapons, it has an oder that lasts. before using tetra, function your weapon, listen to the sound and feel the action. after using tetra listen to the sound and feel. as above ^^^^ a little goes a long way. Q tips on friction areas, slide slots and hard to get areas. suggestion, do not apply on plastic/ dot sights as per instructions. on semi rifles, wipe almost dry on bolt/ slides, the excess will blow back and it burns on the exposed areas of skin it lands on, and it is hot!! the best aspect, it makes cleaning the bore easier after your next range visit. I don't use tetra on mags. shake bottle during the cleaning process.
