Have occasion to purchase several Palmetto Armory AR-10 .308 lowers. Not sure if they are configured like the Armalite,DPMS or other types to accept a particular mag. There are at least 4-major mfg.'s of this type weapon,so it gets a bit confusing trying to determine which type is like which other type,especially when it comes to fitting mags. Have also heard that Mag-Pull makes AR-10 type mags...but then again,not sure which type. So...question is,which mags would I have to purchase to fit the Palmetto made .308 lowers...?
