First thanks for reading............I have some ancient AR15 mags that were given to me by my father. he had picked them up at work in the in the late 80s and for whatever reason hung on to them until recent. I have access to the equipment to refinish the mag by myself and am gonna strip the metal and re-coat, however I was looking for suggestions for a rebuild kit. Im looking for springs followers and floor plates. the springs in a few of my mags are spongy and a couple of the floor plates are dinged up. Living in the lovely state of Massachusetts I don't want to take an undated/marked ar15 mag and put on features that will make the magazine look like one of those evil post ban mags. I know of a few companies who make kits but i dont want to throw magpul floor plates on the mags for example, and make my mags "questionable". Id prefer to rebuild with parts (floorplates) unmarked so that the date of the mags will be next to impossible to prove. any suggestions would be appreciated greatly
