    The reason mid-lengths originally came about is because carbine-length gas systems weren't designed for 16" barrels, and some engineers found that moving the gas port closer to the muzzle than the carbine-length allowed on those 16" barrels was more optimal. Thus, the mid-length gas system.
    Thanks Justin. That makes sense. Both of mine are 16" with carbine gas systems. They both are easy to shoot.

    Because The Chart told them it had to be. And virtually everyone on the interwebz said Buy a 6920 and shoot it.

    Unless you shoot full auto or shoot 10,000 rds a year I don't see how it makes any difference except in length of forearm/rail. And it us what is being made for the military so I imagine that length is plentiful.

    3 gun says Thou shalt shoot only 18" rifle systems, so in two years that may be all you see.

    I'm not sold on 14.5" w/ mid length. I prefer my 14.5" to be carbine gassed.

    They're are plenty of threads of people having problems with 14.5" mids, even from good manufacturers.

    On the other hand I would never buy a 16" carbine, I would only buy mid length.

    The question is, why?

    I have both and see no massive advantage. Granted, both rifles are not over-gassed and run a different spring and buffer combo, but the two shoot incredibly similarly. There might be the slightest ammt of recoil difference between the two, but it's not much. That said, I can feed even the weakest Tula (not that I plan on it, but I have run some very low powered reloads through it) into the 16" carbine and the rifle will cycle every time.

    My experience working with manufactures is this:

    1. Availability - there are just a lot more carbine parts.
    2. Cost - same as above.
    3. Lack of education - most folks really don't know how the rifle works; understanding how to make it work better is completely lost on them.
    4. Customer confidence - "That's the same rifle I carried in the service", "So... what does the Army use?"

    If 3 and 4 changed, 1 and 2 would also change... but as we have seen with about every other consumer commodity, the best is not always the one that wins; humans are strange creatures.
    Please let me know if I have offended you...
    I would like to move on to my next task.

    OP, just so you know... That's what a military, select fire M4 uses.

    Example threads?

    I am looking at buying a BCM 14.5 mid length and would like to know about said problems.
