Just wondering if anybody has had any problem with galvonic corrosion (SP)between ar aluminum lower and the SA80 steel mags. I guess it would be ok as long as the finish on both pieces was intact and it would insulate againist chemical reaction. The nature of the beast being that the finish on the mag keeps on wearing off everytime it is seated or unseated from the mag well. Of course the ar also has a metal mag release, metal forward assist, and a metal bolt release.(to name a few) I have removed a metal bolt release from one of the rifles I have built, and it showed no signs of any chemical reaction. Maybe because I always dry my rifles asap after they have been out in the rain, and always keep the above mentioned friction points well lubed, is the reason I have never seen this problem. Amos
