Help me out here guys. I'm not up on all the buffer talk. I know that the shorter tubes [used with collapsing stocks] are the rage, but is that because of having a collapsing option, or do the shorter tubes cycle the bolt quicker allowing for more rapid bursts [if one has a full auto weapon]?
I have a full length tube and am going to be going with a 16" mid length upper. If I keep the stock I have [YHM metal stock], would that cause a problem with a 16" middy? Currently running a rifle length upper.
