    I am looking at some different AR setups... and I want two major types.

    I want a good distance gun in a SPR config, but I also want whatever you want to call a 14.5 gun setup.

    Does anyone run one lower with two uppers? Is that just a bad idea?

    I am thinking of doing the SPR first most likely as a complete rifle, and just buy a short upper to stick on it. That way the SPR everything is fit well.

    That or I may start building a rifle super cheap(The 14.5) a part at a time then just end up with two full rifles.

    At one point I had three uppers and one lower.

    Here is my billet upper/lower in 6.8 SPC, shown with
    a Spikes dedicated .22LR upper

    I'd do a quality lower build and SBR it. Then you have options.

    A SBR is going to happen at some point. I am working on setting up all the stuff but that is a long term goal.

    I am working on maybe building a cheap lower to play with and see if I am able to make it work..

    How important is upper to lower fit? I have heard different things, I have only ever owned full builds in the past.

    Love it!

    The 6.8 is good out to 300m.
    If I need to go beyond that, I've got a FN SPRa1 in 308 that will get the job done.

    I have had combo's that were tight fitting & some very loose.
    It really does not bother function or accuracy. Some lower receivers have a
    set screw with a nylon tip that contacts the upper's rear pin lug. My billet set
    has it.

    I would suggest a matched upper/lower set. Or at least both from the same manufacturer.

    Played with 300 BLK yet? I like the idea of 6.8 or 300 BLK but will do a 5.56 first.

    Shot a friend's 300 a few weeks ago. Great ballistics and knock down out to about 150m.
    After that it nearly falls to the ground.

    The 6.5 Grendel would be an option if you care to deal with Alexander's BS, I do not.
    6.8 works well for my needs. Shoots right at 1 moa, 85-120gr projectile selection.

    Is that the UBR? What do you think of it?

    I was thinking about it but worried about weight.

    I have tried the MOE and IMOD with the standards as well, not fallen in love with anything yet. The IMOD was the best, as far as feel and lack of rattle.

    Yes,........it's the UBR.
    This rifle is used for hunting or shooting from a bench mostly, so weight is not an issue for me.
    It also ballanced the medium weight barrel very nicely. The Sikes .22LR upper, changed a bit
    since the above picture, & my Adams Arms piston upper now share a BCM lower.
    I have a MagPul MOE stock on the BCM lower

    IMHO.. A registered lower or one with a $300 trigger, etc.. makes economic sense to share.. Not so much otherwise.. YMMV.. Ron
