For sale is a great condition CMMG MK-4.   It has been shot very few times,and is chambered in 5.56/223.  It has a 24 inch fluted barrel, upgraded Magpul grip, BCM Gunfighter charging handle, 2 mags, CMC trigger upgrade and a bipod.  It also comes with the factory box and a hard case.  I will only sell to someone who can legally buy and own a firearm in Wisconsin, and is willing to show it Wisconsin drivers license. I am asking $1000 and it must be picked up in West Bend.
