I know the upper is strong! I have imco sc lower, guessing the bmax lower is a little stronger. is it just as fast? does it handle about the same? im not sure how big it actually is or how well its shaped hydrodynamically. any input?

btw not sure if they ever have changed but im talking about buying a brand new one, thanks

The BMax lower is a tiny bit better hydrodynamics. Strength is the same.
