Sorry so late to the party! [emoji23]
My AUG started off with a TA110 that I bought on a whim and got rid of almost as fast (heavy pig lol), then switched to my favorite ACOG, TA33 GH riding in a Bobro QD Mount (the lightest of this particular bunch, but heavy compared to my TA44C), but now it wears a TR24G in an Aero Mount (total weight of optic and mount is 17 oz.). In spite of being a tad bit heavier than the TA33 setup, it just works out much better for my needs. Here’s a few pics:
