People marvel at the fact that an AK will fire without its top cover but you would be surprised how many parts on an AR you can pull off and it still clocks in. To prove this point, Eric and Chad with IV8888 lay hands on a perfectly functional CMMG Mark 4 LE in the above video, then start deleting stuff from the rifle.
Using a roll of duct tape and a GI cleaning kit for substitute parts, the hack begins with removing easy stuff like the stock, safety switch, and grip before moving on to more important stuff like the rail system and castle nut. Next to disappear are the magazine catch, charging handle, takedown pin, and other assorted odds and ends.
Then it starts to get weird.
