First off you don't want a Flatline. Yeah other people have it, but also there are plenty of people that bought the Firestone tires that self destructed and killed a couple dozen of them. Also there are a lot of people that pay waaay too much for red wine that because it says it's from France they think it's going to be better than California or Australian or Spanish wine. Does that make it a good idea? NO! You can get great accuracy at an affordable price with Custom Products (CP) barrels, commonly found just about anywhere for around $45. Don't pay more than $55. They are accurate and suprisingly quiet while gas efficient and durable, not to mention attractively anodized. They look good, they work, and you can afford them. What else do you need?
