The Midwest Industries Side Folder with MI Stock Tube for Picatinny Rail, Black is a stock that fits Picatinny Rail.

Hinges are supplied to Manticore Arms by Midwest Industries, made of steel, and weigh 6.9 ounces. The hinge can be set up to allow the stock to fold left or right. Hardware and allen wrenches for installation are included.

The Trapdoor Stock is designed with original AR-180 styling and the additional bonus of ample storage space within. Overall length of pull on typical AR-15 style rifles with picatinny mounting is 13.75″, similar to that on the original AR-180 rifle. Weight of the polymer stock itself is 11.3 ounces.

Made from a heavily fiber reinforced polymer the stock buttplate is easily hinged down by pressing a spring loaded plunger on top with a rifle bullet point or small tool. With 8″ of clear length from front to back internally a full size AR-15 cleaning kit with three piece steel cleaning rod will easily fit inside, and the interior width of 1.050″ allows 1.0″ diameter oil bottles to fit. The buttplate measures 1.325″ wide by 4.5″ high and gives plenty of surface for soft felt recoil.

The stock sets your length of pull and cheek position, so it has a direct effect on how consistently you can build a position behind the rifle. Collapsible AR-15 stocks slide on to the buffer tube (receiver extension) — check whether your rifle has a mil-spec or commercial diameter tube, as the two are not interchangeable.
