LUBE... I love it, couple of little drops to keep your pistol blowing back in the face of the other team. I got some of this a NAF 2016 and still it's going. Use it on all 3 weapons. Just get it, you need it you cheap skate. Nothing worse than playing and having a jam that could be avoided. The lid keeps it check and the hole only allows a drop or two out so you don't splash it all over your pistol. Also good for wiping down after a wet game to avoid the rust.
