I now believe my next purchase will be an ar15. but i really on want only one lower and have different uppers. i have search many websites but to no avail. i was wanting to get uppers in at least 30 cal rifle cartridges(they make 50cal stuff for ar's), but also the .223 and possibably .22lr. but i have only seem the larger caliber stuff mostly on ar10's. which is a different platform that doesn't interchange with the ar15. the ar10's they all say the new designs are beefier were need over previous. so i was wander if the ar15 can handle the larger calibers like the ar10 can. from what it seem they go with the ar10 becasue of it's strength.
