Very good point!! Maybe let her handle one of each and see which she likes.The Annoyed Man wrote: I'm not making a pitch for the AR, although it is certainly just as valid a choice; but I am saying that if the AK is supposed to be even simpler than an AR, there is no reason why your mother couldn't learn to feed and care for one. It only takes the will. Without her willing participation though, this project is likely to just put a hole in your wallet the size of an AK just so that the thing will go to rust in the back of her closet. I would worry less about platform/caliber and more about whether or not she will willingly participate,
I do think a '74 variant is a better choice than a '47 for the simple fact it recoils less and should weigh a little less (again, polymer furniture will help here).
If weight of the gun is the main factor, this is one of those rare occasions where even an AK fan like myself has to recommend an AR (specifically, a light weight one...NOT a 20" HBAR...you can go pretty nuts buildling an extremely light weight AR) because they are lighter guns and may be easier for her to use.
