I saw where there is a drawing for a LWRC 18” ICA5 DMR Upper. I am assuming that because it is a piston upper it is still legal in Maryland. Is this correct?
I was looking at the BCM uppers. If you were shooting about 200-250 rounds each outing (1-2 hrs) is there any difference in the BCM light weight barrel and upper compared to the standard barrel when it comes to overheating the barrel? I hope I am not shooting enough rounds to make a difference...
