M1A is a great rifle. Accurate, not all that heavy, not too long or cumbersome, able to zap something a long ways out, plenty of knock down power. I miss having one.
My "reach out and touch someone" urban rifle is a 16" barreled Noveske N6 7.62x51 with a Trijicon TR24G 1-4 power optic on it. In the suburban hell of Tacoma, that's perfect. I've hunted with it and walked 10-15 miles at a time with it and wasn't bothered by it's weight. Got plenty of 20 round mags and a couple 25 rounders. If I lived in a more rural area or the East side of the state, I'd probably want something with a bit more magnification.
Yeah I'm fond of the M-1A. I qualified with the M-14 in the Army. 7.62N is pretty handy for modest barriers too! What is your Noveske weighing? At 9.2# (more like 9.8 for the NM) empty the M-1A isn't all that lite but I find it very well balanced.
