This page explains which Kidon® configurations our store sells and which federal and state rules may apply. It is our store policy, not legal advice.
Kidon® exists because a pistol is easy to carry and hard to shoot well past fifteen yards. Drop the host into the chassis and you gain a cheek weld, a forend, a rail for a light and a mount for an optic — and you can pull it back out in under a minute when the shift ends. In Israel that story is simple. In the United States, the moment a shoulder-fired component enters the picture, federal law starts asking questions.
This is not legal advice and it does not replace your own reading of the statute or a conversation with counsel. It is the walkthrough we give every US customer who calls before ordering.
What we actually ship
The US-configured Kidon® leaves the warehouse as a pistol chassis. The host pistol stays a pistol: the chassis adds a forend, rails and an optic mount, and it ships with a stabilizing brace rather than a shoulder stock. Nothing about that configuration changes the classification of the firearm you install.
What changes the classification is what you add. A vertical foregrip on a pistol, a shoulder stock on a pistol, a barrel under sixteen inches paired with a stock — each is its own line in the National Firearms Act, and each has its own answer.
A chassis is not a classification. What you bolt to it is.
The three configurations
One — pistol host, stabilizing brace, no vertical foregrip. This stays a pistol under federal law. It is what we ship by default and it needs no additional paperwork.
Two — pistol host with a shoulder stock. Adding a stock to a pistol makes a short-barreled rifle. That is a Form 1, a tax stamp, and approval before you assemble it — not after. Folding-stock variants exist for owners who have already been through that process, and for agencies buying on a demo letter.
Three — rifle host with a sixteen-inch-or-longer barrel. Outside the NFA entirely, and outside what most Kidon® buyers are doing.
Four questions before you order
- Which host? Confirm your exact pistol model against the adapter list. A Glock 19 Gen 5 and a Gen 3 are not the same adapter.
- Brace or stock? If you want a stock, your Form 1 must be approved before the parts meet.
- Foregrip? A vertical foregrip on a pistol is its own NFA question. Angled grips are treated differently.
- Your state? Several states regulate braces, chassis systems and magazine capacity independently of federal law. See state restrictions.
State law does not follow federal law
This is where most orders get stuck. California, New York, New Jersey, Washington and others treat stabilizing braces, chassis conversions and magazine capacity under their own statutes, which move on their own schedule. A configuration that is unremarkable in Texas may be an assault-weapon classification in Connecticut.
What we will not do
Your responsibility
Federal law (including the National Firearms Act) and state law may regulate braces, stocks and short-barreled configurations. You are responsible for compliance with the laws that apply to you. Verify current requirements with the relevant authority before ordering.
