“STizon” PP-19 Bizon Kit for 9mm AK

The STizon is a kit for your current 9mm AK to turn it into a Bizon, one of the most difficult-to-get Russian firearms in the US. The internals of the iconic helical magazine have been re-engineered and simplified from the original PP-19, bringing costs down and reliability up.

So what all do you get in the kit? First and most obviously, you get the helical magazine which can hold up to 66 rounds depending on which kit you order. The mag internals are made of aluminum and steel, while the caps are made of injection-molded glass-filled nylon The tube of the magazine comes in two options: black anodized aluminum or a clear durable polycarbonate. Second, you’ll get a machined aluminum handguard in the Bizon style. This will still work on your gun even if you’re not running the helical mag. Last, you’ll get our 4140 steel flash hider, also in the iconic flared-out Bizon styling with wide chamfered cuts, threaded for the standard 9mm 0.5×28.

Available for:

-PSA AKV

-CAI NAK 9

-CAI 9S

-KUSA KP9

Note that the mags and handguards are NOT interchangeable between models.

Find single mags HERE

PSA AKV / KUSA KP9 / KR9: 55 Rounds

CAI NAK 9 / 9S: 66 Rounds

We HIGHLY recommend adding a mag catch to your order as our mag catches are slightly oversized and allow the user to file them to a perfect fit.

We are changing the feed necks for the AKV, KP9 and 9S models purely for ease and consistency of molding. Nothing functional has changed. You may receive either the old or new style while we transition.
