I'm getting ready to place an order with RRA for a Mid-Length A4 Upper and would like to know how much weight difference there is between the standard Mid-Length barrel and the Lightweight Mid-Length barrel?  Also, is there any accuracy loss due to barrel whip in the lightweight barrel profile?  I've seen comments about how heavy the RRA Mid-Length is and that it's front-end heavy, so the lightweight barrel may be the way to go as long as there isn't any any accuracy sacrificed by going with the lighter barrel profile.

THANKS FOR YOUR HELP!!!

About half a pound, and yes, inherently, there is a potential for some loss of accuracy with a lighter barrel, due to both it being lighter and more prone to whip as well as inability to dissipate heat from the chamber/bore as quickly as an HBAR can.

Thanks Steve, the standard 16" barrel that comes in the RRA Mid-length would be defined as a medium weight barrel rather than a heavy correct?

Our standard is an HBAR (not a Bull profile, but they are full HBAR weight under the HGs).
