I am new to my dpms lr-308 and i am trying to find out if there is a kit or upper or some other method that would allow me to use my new rifle with .22lr. I know that this is not a typical set up for conversion but i cant believe that no one else has done this. As of now i am figuring that i will need a different upper, some sort of bolt kit, and mag conversion. Any help would be great. Thank you, SH Also i bought the DPMS model LR-308 but it seems as though it is actually the 7.62 sportical, is there any way to identify the rifle other than the way it looks because the lower say .308 yet the upper (barrel) is stamped with 7.62.
