I recently bought an early 2000's bravo xr upper that had been completly gone through. To my knowledge they are all the same gears in the uppers and the lowers determine the g/r. So my question is if I pair it with a standard bravo 1 lower with a g/r of 1:1.5 will it give me a g/r of 1.5. If not how do I achieve this? Thanks

The STD bravo 1 lower will give you a 1.5 ratio with an XR upper
