Triangle Stock

SKU: MA-5100

Please note, no hinge or mounting block is included, these can be purchase at or a variety of other suppliers.


The Triangle Stock bolts to any standard 10-32 bolt pattern stock adapter or hinge, such as those offered by Stormwerkz and ACE Riflestocks.  It is easily adapted to any AK, and can even be mounted to a Yugo PAP pistol by simply drilling and tapping two 10-32 holes in the rear trunnion (make sure the pistol is registered as an SBR before doing this.)


Made of 6061 aluminum that is bead blasted and anodized black, the stock weighs only 10.0 ounces as the arms and rear of the stock are now scallop cut internally to reduce weight, and with a hinge installed will have the exact length of a true Russian or Bulgarian sidefolder stock. The rear of the stock has a machined rib pattern to give a good grip on the shoulder, and with the use of a hinge it can be configured to fold left or right. The Triangle Stock comes with the stock, two 10-32 bolts and washers. Overall LOP (Length Of Pull from buttplate to face of trigger) with Triangle Stock and Stormwerkz or Ace Riflestock Hinge installed is 12.25″, exactly the same LOP as a real Russian or Bulgarian Sidefolder AK.
