Whats the status of a title 1 m203 receiver if made into a mount for a masterkey?
This is a hypothetical question since I cant do this in WA anyway. But I was looking at the knights armament masterkey setup and was wondering what the legal status of a stripped M203 receiver would be if you milled it into a mount to make a masterkey set up for the m4. Would it still be a title 1 firearm or would it no longer be considered a firearm. I'm refering only to the modified m203 receiver in this one.
I don't have a answer to your question but I think it would be easier and cheaper to start from scratch.

that might be true as far as starting from scratch. but do answer my question because its not obvious. would it still be a title 1 firearm or essentially a non gun? If it were still a firearm could I move the markings to a different area that would still be intact? when you cut up a gun and throw it away is that not legal assuming you chopped the receiver?
The masterkey that I am familiar with is a short barreled shotgun underneath an AR15.
The following is my best guess!!! You still need a tax stamp. The stamp would be for a SBS or an AOW. It is an sbs if you have ever had a buttstock on the gun. It is an AOW if it never had a stock. I have been told that 12 gauge loads over time will damage a M203 receiver. So I would not use a shotgun insert on the M203.
But I could have my head completely and deeply inserted into a dark posterior region.
You got me confused, are you asking about making a 12 ga master key or are you talking about M203 launchers? You can get virgin M203 receivers and get a Shivak 37mm tube for it making it a non DD but you would be limited to smoke, flares, and gas only.
A 12ga may have started life as an AOW (less than 16" with pistol grip) but once you mount it on an AR in the master-key configuration, it then becomes an SBS requiring a $200 tax stamp.

well if you looks closely at the mount for the KAC master key set up it looks like a cut m203 reciever that the remington 870 attaches to and then the whole thing is mounted to the m4 in the same manner as a m203
master key
I fail to see the logic in destroying an M203 receiver, to make a mount for a 12 gauge... If you want a 12 gauge, simply use a 40mm to 12 gauge adapter in your tube. If you want a 12 gauge shotguun, simply buy one. If you want a 40mm, simply register it and buy one.

If you machine down a 203 mount to attach a breach shotgun to it, it WILL crack and break with repeated use. When I was still in the service we experimented with many different variations of this idea. The only way we ever got the to work reliably was to build custom mounts out of steel and that basically made the rifle so heavy it was miserable to hump around. In the end we just went back to carrying an 870 breach gun in a carrier attached to our side.

Im gunna call BS, I use to own a Masterkey shotgun, the mount was made by the guys at TNT armory. (no longer in buisness) The mount cost $125.00 back then. It worked just fine and was the same as a m203 reciever.
It woulden't be cost effective to use a title 1 M203 reciever as a shotgun mount, the reciever would cost over $1,000 so no point. You could have one made for less. I doubt there are any laws because once you mill the whole bottom off the M203 its no longer a firearm.

I can support this. (Logicaly not with acual BATF statments.) when was the last time they were logical?
If the M203 can not be assembled (at all) due to milling the reciever then the reciever is nolonger a firearm. If the finished product can mount a modified 37mm or 40mm barrel then it is still a firearm.
I think it would be cheaper to start from scrach, and no legal issues it just a mount.
Best way might be to use a 203 forging, and go from there. It would never have been a firearm or DD that way, plus you aren't ruining a 1000 piece of equipment. GROG
as i understand its a no go due to the fact the masterkey becomes a sbs. sbs are not allowed by state law but destructive devices are good to go just get a 40mm and a 12ga adapter
if the shotgun still measures over 26in and shotgun barrel over 18in its not a SBS.
You can mount it to your rifle but the shotgun would be longer than the rifles barrel, so it'll stick out a little on a 20in.
I dont have pictures of mine but this one is a 14.5 in barrel
just so you know, the shotguns were only held onto these mounts with four 4x24 screws if I remember right. these mounts were way heavyer then they needed to be.
