The ASA/HVC mount won't stay tight despite repeated tightening of the phillips head screw that holds it in place. It doesn't leak air, in fact the assembly does tighten up up when you put air on it. The sight rail flexes too much to stay put. My son just took it off because it rattled.
Overall this is a great gun as it is. A little work puts it in the 'killer' category. Some thoughtful upgrades, rather than just tossing on Nitro and every gimmick out there will produce a very sweet piece. It has very good performance out of the box and looks great. The only down side is that I wish we had gotten the bottom line instead of the Vertical. For under $100 this is a fantastic deal that I would recommend as an alternative to your basic Spyder/Tippman/Rebel buyer.
