You sure can, and it's easy with these guns, if you wish you can remove the barrel and place it on (across) a cardboard box with 2 small "v" shaped notches cut at opposite ends to support the barrel, look through the barrel at a distant object through a window, then without moving the gun or box raise your line of vision and look through your scope or iron sights, adjust the scope or sights so they are at the same point and you are done. It does not matter if the box is moved at any time in the sighting process as long as ech set/pair of times you look through the bore and scope there is no movement in between, you can even pick it up and put it away and finish at a later time with no problems, even the distance you are looking at should have no effect since you are looking on 2 straight lines of sight and this is only for a "boresight" to get you close to the bull anyway. If concerned try to pick out an aiming point at the distance you want to shoot, 50, 100, 200 yards etc. Your final fine turning will be done at the range anyway. All this talk about it I might as well do it. I put a scope on my Tracker II to try instead of the Red Dot that has been on it. I am going to set it up and bore sight it right now, I'm going to set the gun up on the kitchen table and aim at the center of the wreath hanging on my neighbors door!! I want to get it done before my wife gets home!!....<><.... :grin:
