Original Colt Defense Manufactured with roll mark: "Launcher, Grenade M203 40mm" Title 1 Firearm, Transfers on a 4473. NON-NFA ITEM!

Description:

For the first time ever, the Colt M203 Launcher offered in 37mm, built in a lightweight, single-shot, breech-loaded weapon specifically designed to be attached to the M4 Carbine, the M16A2 and M16A4 Rifles. It creates a versatile combination weapon system, capable of firing both 5.56mm rifle ammunition as well as the complete range of 37mm ammunitions.

I wish I would have bought one of the last batches.  I don’t think I will be getting one of these without a steep discount.

I do wonder, are these going to be roll marked or have these also gone the way of laser engraving?

Five years ago, it was receiver only - you still had to get the barrel .....

If I remember correctly, it was originally for the receiver and barrel, it was just the barrel shipped separately.

Since when were 37mm considered a firearm? I thought the 37mm were pretty much a novelty.

The original sale had 37mm smoothbore barrels. Consequently, AU could ship them as Title 1 firearms.

LMT 37mms are not firearms because they are somehow modified and you supposedly can't put a 40mm barrel on them.

Yes. That is why they're Title I firearms.
Any real M203 receiver is.
