I have a savage axis 223 and looking to up grade to a chassis system. The system I was looking at are the mdt lss/xl, or the xlr element. I know there have been threads on here about them but they were a while back and was wondering if anyone has any new remarks regarding the two chassis system? I have done my research on both. A question that I have is, what is the difference between a v block and a u block. The lss is v block and the element is u block. What is the difference and is one better than the other.

Thanks in advance
