Strike Industries AR-15 Rifle Pit Stock - Blue - This is the Strike Industries Aluminum Pit Stock. It's time to rethink what you really need a stock to do. It's time to rethink what a stock can do. It's time to reject the status quo, the compromises we all have taken for what is, rather than think about what can be. The AR as a compact platform, has always felt like an amalgamation of ad hoc fixes rather than a dedicated system of components designed from the ground up to work in harmony with the shooter. Once again, Strike Industries has the solution: the Pit stock system. Features Made in the USA ; 2 in 1 adjustable or fixed; 3 Position Adjustable; Lighter than a mil-spec m4 stock but 2x more durable;
