I haven't used this product much because winter came and the shooting stopped but I tested it at 100, 200 and 300 yards. Works great at 200 and works well at 300 yards. I see 556 holes on a Birchwood Casey black repair target at 200 yards; There was some difficulty at 300 yards, but the target was well used and a little worn. I also lined out a used black and white 9mm target at 300 yards and could clearly see these holes. I think it will work at 300 yards with the less used Birchwood Casey and I'm pretty sure I can see 556 holes on a black and white target. The included tripod is more than adequate. in that it does what I need at a very good price.
