Don’t worry, nothing will change…I can’t wait to get my hands on this thing. USPS MO will go out later today. And sorry, but I’m keeping both barrels. Thanks again for an awesome deal!
Honestly the MRP’s BARELY weigh any more than a regular/standard upper.
I wish I still had the numbers here with me, but I personally have weighed and compared the CQB MRP to a standard 16" Colt upper and the difference was so minute that it mattered not.
Wes over at MSTN has charted the numbers as well, with the same results.
A regular/standard 16" upper with a FF rail installed, weighs almost the same as an MRP. Bottom line. (Very slightly heavier MRP bbl contour is the only real difference, and I’m talking slight.)
Now if you are going to drop down to an SBR, then that would be a whole different ballgame…
I have held both the MRP and regular 10.5 inch uppers side by side and there is a significant difference in my hands. I do not have exact weights though.
