Command Arms Accessories (CAA) is now selling a stock tube for stamped AK-pattern rifles. The tubes allow for the use of an M4-style adjustable buttstock. The polymer tube has six positions for adjusting length of pull.

CAA advises the tubes allow the stock to fold. Depending on how you set it up, the stocks can fold to the right or the left of the gun. The company used a large folding button to allow for easier manipulation under stress.

The tubes are currently available in only black. They have a suggested retail price of $124.99 and are backed by an “Unconditional Lifetime Warranty.”
