To basicly clean a Rev. you don't need to take it apart. you just need to open it. That was not my point. My point is when you want to buy a gun as if you are buying a car, as one of the replies said, do you say to the sales man, "wow, thats a really nice red car". then buy it? Of course not. Yoy always look under the hood, no necessarily take the car apart, but look under the hood. Same thing here. I want to look under the slide to make sure the gun is not made from Lego's. Is that so hard to get a grasp on? when you buy a $500,000 house do you say "yup, that's a house here is you money" or do you inspect the house and have someone else inspect the house AND even take the BOLD step of walking inside the house. God knows that would be a cardinal sin. Get my point yet? Geeze!!
