    Also really like your rimfire build, good selection of components and I'm impressed you got one that will outshoot a 10/22. I guess it depends on the 10/22, mine is 'accurized' with a nice trigger and barrel, it can consistently shoot sub-Moa at 100 yards and last week I got a couple 0.5' 5-shot groups at 100 yards with mine. Now usually a factory stock 10/22, even the Target model, will not do that, but still they are surprisingly accurate, even a run of the mill 10/22 with a sporter barrel, decent glass and ammo used, should be able to hold 1" 5-shot groups @ 50y. Curious, can your upper match that? I'm really interested in that, been looking again at the M&P 15-22's and other .22 options for my AR. I used to have the 15-22, then just got tired of the shotgun-like accuracy beyond about 30y or so, you'd get 2 to 3" groups at 50, 4" or more at 100y. From what I've seen the 15-22 is a nice training rifle for AR training, a trainer for kids, and a close-range plinker, and it is fun and reliable, but it is seriously a 3 to 4 MOA rifle. For me, that's just not acceptable in ANY 22 I own. With .22lr uppers, the only ones I know that are really 'precision' are the spendy Compass Lake Engineering uppers, but wow, $1000+ for an upper, and those have some limitations of their own.

    So yeah, if you've figured out how to build a reliable and 'accurate enough' upper that beats a 10-22 in accuracy, I'm interested. Who makes the bolt assy for RTB, is that based on the CMMG pattern actions?
    I will swap a bigger scope onto the rimfire upper and shoot it Friday. I have some Green Tag, some Federal match and CCI standard velocity. My 10-22 is a stainless sporter that would probably freak out if I shot decent ammo through it.

    Yes, CMMG makes the bolt assemblies and barrels for RTB (Right To Bear).

    Very nice. I have done very similar, but with the M&P15-22 being set up with an 3-9 and offset RDS just to get me used to that a little quicker/at lower cost.

    I made it to the range much later in the day than I would have liked. I had a Nikon P-Tactical 2-7x32 rimfire scope mounted and a front bag. Generally, groups hung around 1" at 50 yards, with Green Tag printing between .5 and .75".

    I did not have time to verify the Green Tag groups were repeatable, 2 five shot groups can be a fluke.

    A more powerful scope and less rush would have tightened groups a bit, but its safe to say it is closer to a 2 MOA barrel than 1 MOA, at least with me at the trigger.

    Reliability continues to satisfy, no malfunctions yesterday and the trigger is so much better than my 10-22 it's ridiculous.

    Excellent 50y accuracy in a .22 upper, nice build. IMHO anything 2 MOA or less at 50y is pretty darn good in an upper that doesn't have a high-end barrel.
