Best AK Stock: Tube vs Skeleton vs Triangle

The best AK stock in our lineup is the TS-9RP Triangle Stock, because it is the only JMac stock that combines a 9" length with a 0.275" built-in cheek rise and a molded rubber buttpad. Tubes are the lightest, from 3.1 oz, and the SS-8RP SS® skeleton stock has the same rise and pad in 8". All of them mount to the same JMac SM mount family.

What is the best AK stock?

In our lineup it is the TS-9RP Triangle Stock. It is the only JMac stock that combines a 9" length with a 0.275" built-in cheek rise and a molded rubber buttpad. The SS-8RP is 8" and the TS-9P has no built-in rise.

Does an AK triangle stock take a cheek riser?

Yes. The TS-9RP already has a 0.275" rise, and both triangles take CRIM risers in 1/4", 1/2" and 3/4". The skeleton stock and the arm bar take them too.

Does the triangle stock have a rubber pad?

Yes. Both the TS-9RP and TS-9P have a permanently injection-molded rubber buttpad.

Where do the QD sockets go?

The tubes have integrated QD sling sockets that stay reachable with the stock collapsed. The TS-9RP has integrated QD sling sockets.

What mount does an AK stock use?

  • SM-1913 mounts to a 1913 rear rail or a host with a JMac RSA adapter.
  • SM-5.5 mounts on the 5.5mm folding-AK hinge pin. It fits the Arsenal SGL 31-94, 31-95, 31-84 and 31-85, and fits with conditions on the KUSA KP9 and KR9 and the Arsenal SGL 21-94.

The AB-9R arm bar uses the same mount. The dust cover for the Zastava M92 is covered separately.
