Just a drop.
Awesome stuff. Used to come in a pipette bottle which was so much better as the new bottles neither seal or apply as well but still worth every penny. One drop is more than enough to lub an ETek5 bolt. Great for pops, Tippmanns, marker regs and anywhere the manufacturer recommends using oil. If it's grease you need try TechT Gun Sav. Used properly they will last you years.
Works well. Everything you could need
before i purchased this item i noticed the balls we curling when being fired didnt think it was a big deal. Then i bought this item now it shoots strait which is helpful.
