I am wondering if the feeding tube on the prowin M4 unit is longer than standard hop-ups. I have viewed a number of vids and it appears to be so but I am unsure. If someone can supply me with the info that would be great. Even better if they were to use calipers and could measure that would be even better. Does the unit match up to other aftermarket ones in measurements or do they extend further down once installed? Thanks for your help.
