Well I got a reply this morning when I got up, so not sure when he got back to me, but he,s apologized for the problem said he,ll look into and check his vernier gauge measurements and rectify as soon as, also I got a full refund of which I wasn't expecting or didnt want tbh, as that wasn't the reason I contacted him,but fair play to the guy, he's told me to keep the mags I purchased, sounds like a sound guy to be honest, his email wasnt as basic as Ive written here, he's gone into a lot more detail......☺
