Agree with jayrando....it works!
And he's right-it does require a re-zero,because POI rises after recommended application.
I was pretty skeptical....but plunked down $30 for a 4 oz. can.Several guys had told me it was a great product - and they all shoot more than I do.
But here's another use: coating the inside of sizing dies.Definitely reduces friction.
I cleaned mine with acetone;let dry.
Apply Microlon Gun Juice; let dry overnite.
Repeated the Gun Juice over 3 nites,on a set of my oldest dies.
It's a definite difference you can feel.
