CZ’s Scorpion Evo 3 S1 is 100% made in the Czech Republic. This is fine for a pistol but, in the U.S., poses importation problems were it a rifle and prohibits those wanting to turn the pistol into a rifle (including into a registered SBR) from doing so legally. We have the perfectly understandable, totally commonsense 18 U.S.C. § 922(r) of the 1968 Gun Control Act to thank for this, and what it all means was previously broken down in this post. What it meant to CZ-USA was that providing the Czech-made, factory folding stock to U.S. customers first required replacing at least six of the Scorp’s 15, 922(r)-relevant parts with U.S.-made alternatives. . .

As a refresher, 922(r) states that an imported, semi-automatic rifle can have no more than 10 foreign-made parts from a list of 20 specific parts. CZ’s Scorpion in pistol form has 15 of these parts, but adding the Czech stock bumps it up to 16 while also turning it into a rifle that’s now subject to 922(r) compliance.

Therefore, CZ-USA’s compliance kit replaces the muzzle attachment, trigger, disconnector, pistol grip, magazine follower, and magazine floorplate with U.S.-made versions.


Some of these parts are clearly marked “CZ-USA” to make their country of origin known. Some of the parts are not, but do differ slightly from the Czech ones to ensure you’d prove victorious as the first non-corporate defendant in a 922(r) violation case.


While plenty of folks are happy to ignore 922(r) in part because no individual has apparently ever been charged with breaking this law, nobody wants to be the test case and I assume CZ-USA doesn’t want to bear potential responsibility for that, either.

Therefore, the factory stock is only going to be available with the 922(r) compliance parts for the time being. MSRP for the whole shebang is $199. The stock won’t be sold on its own until there is a sufficient aftermarket in the U.S. such that a stock purchaser could become compliant without requiring CZ-USA’s parts.


The aftermarket options are already starting to appear, too. Coincidentally, some parts from Yeti Wurks also showed up in the mail today:


Everything here — CZ-USA and Yeti Wurks alike — will be reviewed shortly. Stay tuned.

  1. Love the look of that stock. So very tempted to buy one of these or an MPX or a Bren to play around with, would love to compare to the SP89 and 9mm AR SBR.

  2. So the actual 922r kit disappeared from their store. Is there a way to actually purchase these? The post says now shipping. But I have searched, and it doesn’t show up for me.

    • It isn’t on the CZ-USA webstore yet, but it’s coming soon. They’re also hitting distribution channels now, so it’s possible your LGS could get one through one of their distributors even faster.

  3. If I didn’t have expensive home repairs to pay for, I would pick one of these up. Maybe some time next year. There is an FDE model coming with a few improvements.

  4. Whats stopping me from using an electro pencil on the original parts to put “made in USA” on them

  5. Wait… the magazine body, floorplate and follower count as parts for 922R compliance?

    That seems positively tailor-made for the purposes of screwing someone over.

    • Yeah, a lot of rifles (e.g. imported AKs) are only compliant when U.S.-made magazines are used. Insert a foreign magazine and you may well be violating 922(r). The list of relevant parts is:

      (1) Frames, receivers, receiver castings, forgings, or castings.
      (2) Barrels.
      (3) Barrel extensions.
      (4) Mounting blocks (trunnions).
      (5) Muzzle attachments.
      (6) Bolts.
      (7) Bolt carriers.
      (8) Operating rods.
      (9) Gas pistons.
      (10) Trigger housings.
      (11) Triggers.
      (12) Hammers.
      (13) Sears.
      (14) Disconnectors.
      (15) Buttstocks.
      (16) Pistol grips.
      (17) Forearms, handguards.
      (18) Magazine bodies.
      (19) Followers.
      (20) Floor plates.

      …and again, a maximum of 10 parts from that list are allowed to be foreign-made on an imported, semi-auto rifle. If it contains more than 10 parts from that list (and it does), then numbers 11+ have to be domestically manufactured.

  6. Any word on of they’ll now produce a “rifle” variant for those of us unfortunate enough to live in states where the NFA wasn’t restrictive enough?

    • My guess — and it’s completely conjecture at this point — is that we’ll see a carbine version pretty soon. Now that CZ-USA has the U.S.-made parts to make it compliant, it would be as simple as CZUB shipping over a version with a 16″ barrel that’s missing the parts in the compliance kit. CZ-USA slaps those parts on here and now it’s ready to go in rifle form. It’ll likely have a rifle-length handguard. If I were CZ-USA, I’d be working my tush off to have one ready to announce at SHOT Show 2016 and try as hard as possible to have them for sale during tax return season… or, at latest, by this time next year to capture Black Friday and holiday shopping, etc…

  7. Jeremy…how or when under the sun can I get what looks like a muzzle extension illustrated in your post. To get my barrel 16″ legal. As I really dont look forward to doing the whole trust/tax dance . I wish CZ sold a 16″ barrel period for my Scorpion.

      • Yeah, it’s a suppressor (Liberty X as Tex correctly linked). If you wanted to legally turn your Scorp pistol into a Scorp rifle without a tax stamp, you’d need to permanently attach — it doesn’t count as barrel length unless it’s permanent — something to bring the barrel length up to 16″. Normally that would mean pinning and welding on a muzzle device like a flash hider or brake or linear compensator or something. In this case it would have to add almost 8.5″ to the end. You could look to a company like Strike Industries to buy a faux suppressor. The only real hitch is that the Scorp’s muzzle thread pitch is pretty weird. But if a gunsmith is going to pin & weld a muzzle device onto it, they can probably turn the muzzle down to a more common thread pitch at the same time…

  8. Has anyone found a decent trigger kit for it yet?
    That’s the thing keeping me from shooting mine more.

  9. Wow–I’m stating the utter obvious here but I think a lot of us feel like a kid in a candy shop (albeit a very EXPENSIVE candy shop to be sure). That said, it’s quite rare that one can acquire such a firearm absent going through the obligatory Federal hoops–so the fact that this is becoming available even though still requiring the needless extra (kit) steps makes it a certain success. Sure you can get a Kel-Tec Sub2K with a 33 round Glock Magazine for a fraction of the costs but the CZ just exudes “manliness” in that “Tim Allen” way…Seriously though, I’m in.

  10. As soon as my form 1 application is approved I’ll worry about finding one of these. There is no need to skirt constructive possession issues until I have my ducks in a row.

  11. lol, 922r is irrelevant

    Guys in flyover states with lots of land, enjoy your mail order unregistered SBR
