    3pack of gen 3 40 rd mags

    Posted by Jim on Feb 19th 2021

    These seem to be well made, they are definitely better made than the gen 2 mags. Hope they hold up in the sub zero weather. Usually buy metal mags but wanted to try these lighter and quieter gen 3’s Probably going to buy another 3 pack and test them in the snow, cold. Will also test them being dropped on rocks etc. Need to know if I can depend on them
