American Tactical Imports are distributing the new Head Down HD-F AR stock. I like the design of the curvy cheek rest combined with an angular lower. The stock is clearly inspired by other popular AR-15 stock but lack features such as storage compartments, no doubt to avoid patent issues. It will be available in black or flat dark earth with an MSRP of $109.
UPDATE: There may be battery compartments inside the stock. The press release did not mention them.
