Precision machined. Billet Aluminum. Modular. Made in America. The Triangle Stock from Ace is all these things and so much more. The time-tested design of the old, stamped triangle AK47 stock has been revamped, beefed up, and introduced in billet and modular to work with any Ace LTD/Lage Mfg Receiver Block or Folding Mechanism. A ruggedly textured buttplate prevents slipping and there is a non-rotational QD sling swivel pocket on either side.
