If you adjust your velocity it turns the bottom pin
I bought this gun off of Ebay brand new and I loved it right away. This gun shoots really accurately right out of the box. The only bad thing is it's kind of loud. So if you want a better sound to this gun, don't use CO2 or the stock barrel. Use Air and a 16" J&J ceramic barrel. I can barely hear it when I shoot it by my self.
It's very durable. I fell on it because I was running a way in a speed ball Tourny with my friends. And this was my back up. I screwed up my Ion Xe and had to forfeit that round. I went to grab my MR1 and dropped it in the mud. I sqweeged it out and it works better than it did out of the box. I used it for a while. Now I sold my Xe to buy an A5 so i can have two woodsball guns.
This gun is still a great gun even though its 2009. Its very durable and can take any hit. BUY IT!!
