    getting the jitters out with sight in. first group is way low second 3 shot string is a little higher as i fine tune the sights

    im exceedingly pleased as one 3 shot string was about .8 moa not an easy feat at that distance. finally got it dead nuts on

    six 10s and one flier in the 9 ring due to faulty sight picture

    at this point im seriously considering their flattop version as a dedicated scoped upper.

    I can certainly see why. Would you just interchange uppers or would it be a different rifle?

    just a different upper. the fit on rra upper/lower is crazy tight. my lower is a standard rra lower the upper is their nm upper and i dont see how the fit could be smoother or tighter. my 458 socom upper fits just as tight.

    still missing the bolt catch its on order though. broke it last weekend. pita today without it.
