The PBStick is by far the best lube I have EVER used. There is nothing like it out there. All you do is pop off the cap and rub it on your bolt. It's super slick, doesn't get on your hands, and lasts crazy long. It's been about a month left and I still have my first tube! It's only $5 too. That's way cheaper then anything i've seen out there.
Buy this...do it and do yourself a favor. It'll make you lower your LPR and make your gun shoot crazy smooth. No more messy hands either.
