I know the polymer mags are lighter, I just need a ballpark.

assuming you're talking about 5.56/.223 in a standard mil spec 30-round mag... it's about 1lb each.

Caliber and bullet weight might help

roughly over 1 lb, close to about the 20 oz of soda or bottle of water i think..

I pulled 3 random Colt 30 rounders out of the closet and they weighed between 17 and 18 ounces each on a USPS scale. Fully loaded. I'm pretty sure they were filled with Winchester 55gr Q3131A.

around 1.1...hmm. just been trying to figure out how much unloaded rifles weigh when loaded figures are given and vice-versa. it amazes me how many rifles made using modern technology and materials weight significantly more than 50 year old designs.
