Gun vanity - Are KPOS conversion kits street legal?

Posted on 11/16/2015 9:23:42 AM PST by Perdogg

One the weapons used in Spectre was a handgun with a KPOS coversion kit.

Are these street legal in the US and does any one have any experience with them?

I would like a FN57 with a KPOS. In fact, I would prefer this platform.

Any thoughts.

I believe that this would require a tax stamp to be legal. What you are creating is pretty much an SBR.

Pretty sure putting KPOS kit on your handgun makes it an SBR. And you’ll need a tax stamp for it.

That would come under the “manufacturing” label and require an FFL as well as a tax stamp.

Looks like a KPOS is nothing more than a carbine conversion kit for a pistol. Similar to http://www.mechtechsys.com except the KPOS looks like it turns a decent pistol into a hovered up toy. I don’t see how this falls under NFA.

From what people and the manufacturer seem to be saying, there is one version with a stock which is an SBR and one version (the “pathfinder”) with an AR pistol style padded buffer tube that they are claiming is just a pistol. They even warn you not to put a fore grip on it. I’d want to see a letter from the BATFE though. For $600 I’d just build an AR pistol anyway.

Free people should never have to ask questions like this.

I can see how one might want to lumber around with "the most compact and durable PDW converter available which incorporates a Five-point ergonomic weapon grip, a One-point tactical sling adapter, and a fold-to-the side compact Buttstock with rubber buttpad,"

A pistol with a foregrip is an NFA weapon, as is a pistol with a designed shoulder stock. Accordingly, I think you would have to Form 1 a KAPOS conversion kit, pay your $200, get fingerprinted and local LEO sign-off (or register it to a trust), etc.

I haven’t looked closely into this.

Same concept as hollow points, the talisman of shooters who believe that magic ammo can make up for ignoring target & sight alignment along with trigger control.

But hey, a willing seller and a willing buyer is what makes for a great free-market system. More power to the entrepreneurs that come up with these things.

It’s NFA because it creates a short-barred rifle (stock + barrel under 16”).

Stupid law, but there it is. Requires a Form 1 NFA “manufacturing” application
with $200 tax.

Were you to just put a vertical fore grip on the pistol, that would be deemed an “Any Other Weapon”, with same requirements.

Like MeganC said: a free people should not have to worry about such things. The fact that it is obviously & objectively a weapon should suffice to meet “shall not be infringed.”

If I wanted a 5.7 “no really it’s not an SBR” pistol I’d probably get one of these:

Cheaper if you don’t already have an FN 5.7 and you get to use the big P90 magazines.

How does it “improve accuracy and range?”


It will not improve weapon accuracy or range unless you add a longer barrel to the pistol. It will improve the accuracy of the shooter because shoulder fired is more controlled.

With that said, if the OP or anyone else is interested in legally obtaining or building something like this the best avenue is to visit your local NFA dealer, preferably an SOT (manufacturer), and tell them what you want. They can guide you through the process and help you with the application.
