I was at the gunshop awhile back and thier gunsmith was there that day and i got to chatting with him on the diffrent length gas systems on an AR15 and he said he dosnt like mid length gas systems due to short stroking issues with some of the set ups hes used and that thiers no standard spec almost and every brand will run slightly diffrent gas tube sizes so thier not as universal like the carbine and rifle length mil spec stuff...is this true or BS? Another thing he said was in theory the mid length is a softer shooting and not as harsh on the rifle as carbine length set up ,its also not gonna handle being gunked up and dirty as well as the carbine ...is this BS?
I have had absolutely NO trouble with mid length AR's, not a single misfeed, Brass case or steel, have two mid length now, one has an m4 profile barrel, the other a heavy barrel! Come to think about it, haven't had a misfeed in any of the five AR's I have built, Bought all uppers complete though! Just milled and assembled the lowers! Two uppers from one Manufacturer, the other three all from different ones! ALL five gas tubes Mil Spec!

Ive never even paid attention to it before really but online it seems like such a big thing i figured id ask about it... Ive owned one mid length (BCM Recce) and i sold it when i needed cash ...my Colt 6920 i like too much to sell and preffered shooting it over the BCM.
