    Carbine length gas system mated to a A2 lower with rifle buffer and spring lower?

    Was at the range to night and on the rack was a used AR which appeared to have a M-4 profile 14.5" barrel with a pinned Phantom flash hider and a carbine length gas system which was mated to a standard A2 style fixed stock lower with a rifle buffer and spring.

    It looked strange but the counter person stated it ran like a top.

    Would this system work and if so what benefit if any would this combo offer?
    We are all inclined to judge ourselves by our ideals; others, by their acts.

    From what I've read from several posts you mate your buffer with your stock and since you have an A2 stock and buffer tube you'd use a rifle length buffer.

    I could be wrong but I've read that on quite a few different posts.

    It most likely does run like a top.

    The rifle buffer is the most reliable setup available.

    Higher mass and lower spring force makes for nice slow cycling.

    Many companies built guns in a similar configuration during the "Assault Weapons Ban." Although I did not like the configuration the guns worked fine. I also know of many officers that prefer A-1 stocks on their 10.5 to 16 inch guns with carbine length gas systems. Their guns work fine. The A-1 stock uses the same receiver extension and buffer tube as the A-2.

    Im sure it does... That's essentially what the Vltor A5 is, which many of us are using on CAR and Middy weapons.

    It'll work better than a carbine buffer and spring.

    Arguably the best dude.

    Although I hear the A5 is even better. Looking forward to trying it.

    It feels the same as a rifle to me.... not really BETTER. But you pick up a sliding stock and keep the longer buffer action.

    What about the reverse... rifle length upper on a carbine buffer/spring lower?

    Can work... but is the reason for the USMC wanting the A5 set up... to keep the rifle buffer characteristics with a slider stock.
