This is a question for those of you who shoot competitively with QD cans. Like many of you, I have a beast of a rifle from a weight perspective. 19 lbs on an AICS, with a big MTU contour barrel. Do any of you with QD cans REMOVE the can for shooting unsupported positions? I cant imagine adding another 8" of barrel to my rifle with another 1-2 lbs off of that and having to sling up to shoot sitting, unsupported prone, or off-hand. Is the idea of removing the can practical? If not, it seems that I would rather have a direct thread on rather than a QD.
