Greetings fellow Southie. Your best bet would be to call DPMS directly or post this in the inustry forum under DPMS. DPMS has excellent customer service and I am confident your questions will be answered with a call or industry post. Thier website is okay...but it definatly lacks a few things. IIRC, they still had my AP4 Panther labled as LE Only on thier website....they must spend more time hiring vets and building great rifles than updating websites, so I can't fault them too much. Give em a call, I am sure you will be taken care of.
Hope the SD winter is treating you okay...I lived in Northeastern SD most of my life and 60 below with wind chill and feet of snow is not something I miss much...Here in Nebraska, we just got our first snow fall of around 4 inches last night and its nearly gone. I miss the hunting/fishing and people, but not the winter.
Take it easy up there?
