Kevin McDonald lives in Seymour IN, which is only 20 minutes from house he makes the MAK and it is very nice. He is also very helpful with just about any question you might have. I have a 260 caliber and i love it. it is a real shooter. last Sept i shot it out to 1400 yards. hitting a 20" X 40" target.
you use a rem. 700 action . Long or short. i used the short. the repeater uses a Accuracy International mag. and then you buy a barrel of your choice. i used 28"Brux with the interrupted fluting topped off with a shawn Carlock muzzle brake so i can see my bullet hits and the butt stock can be anything that will fit on an AR platform. He has a new feature that allows you to remove the butt stock with just one click of a button. so if you want a 30" barrel you can store it in a smaller case in just one click to remove the butt stock.
