Bought our nine year old daughter a Smith M&P 15-22 because she really loves shooting the AR but my AR tends to get a bit heavy for her. So I went with the M&P for its polymer construction and the reviews about its reliability. UPS delivered it to me today and she and I stepped out back and shot a total of 200 rounds of Winchester, Federal, and CCI. I am impressed with this platform. No fte, ftf issues. Accurate. And it was light enough she could cycle through two 25 rd mags with no fatigue. Now I'll have to order at least one more haha. She wants to accessorize hers and after I've shot it, I am going to keep one or two around for tac training. I only have the GSG to compare the 22 lr with, but I am sold on the M&P.
