Spartan Precision Equipment Adapter Dirt Plug Features The Spartan Precision Equipment Adapter Dirt Plug seats directly into the 12mm opening of a Spartan Classic Adapter sealing out dirt mud and grit whenever a bipod or tripod is not attached. Because the Classic Adapter is bonded permanently into the stock keeping its opening clean is important for a reliable magnetic connection every time a support system is clipped back on. The plug is molded in black to blend in against most stock finishes rather than standing out as an obvious add-on. It is a small inexpensive piece of insurance for an adapter that is otherwise a permanent part of the rifle. Selling three plugs per pack means a shooter can keep a spare on hand or equip more than one rifle without having to reorder right away. Each plug is compatible with every Spartan Classic Adapter so there is no need to match it to a specific bipod or tripod model. Popping the plug in and out takes only a moment making it easy to remove before a hunt and reinsert once the bipod comes off. For anyone running a Spartan Classic Adapter this dirt plug is a low-cost way to keep the mounting point clean and ready.
