Sweet. I used it in my AR, glock 23, Taurus pt140 and my mossberg and took them to the range today. When I got them home I could still see the coat of oil on the bolts. Looks like a winnerDLeeHarley said:I use it religiously on my weapons! And it's the only stuff I use on my S&W M&P's since it works with polymer coatings great. Now if you've used a regular oil product already on a weapon you need to clean ALL the oil off of it first. Then use sparingly. It stays where you put it and doesn't thin out very much as your weapon heats up. I think you'll be very happy with it and it's made by Hoppe's too! Keep Your Powder Dry!
