Great info - thanks for sharing! Would be awesome if you ever get a chance to document a DO semi conversion as well.

I think there are <135 Maremonts from the SNs and talking to folks who actually acquired them directly from the factory. I’m pretty sure about this number. There are prob 1.5-2X many RIAs, but I haven’t seen any firm factory numbers and that is just a guess (50-100 by others (Erb,Metro,KAC,Springfield,T161,…) ignoring the Stemple disallowed guns My WAG - 300-500 (yeah, pretty big range).

Just for the transferee (receiving) trust & related responsible persons

Individual can transfer to a FFL/SOT across state lines. You do NOT need a FFL in the same state as the original owner. There is a potential benefit to using a local FFL - can make shipping a MG much simpler for a non-FFL… The other case an individual can transfer across state lines is for a C&R gun where transferee has a C&R FFL

Intriguing - never heard of that - I guess can see how that might work if you just grind off the raised “link outlet chute” piece welded on the top of the m60 tray….

You will need a different account Each account is associated with only one entity / person

I have quite a few barrels with fat gas systems, but never tried swapping gas system styles on a barrel before. I think that when you chop down an E3 long barrel to commando length, you might have to open up the gas port slightly. I'm def interested to hear Aaron's take on this...

Cool stuff - thanks for sharing the pics and story!

Fwiw, I’ve only seen paper tax free forms where all info matched for the items except there were multiple serial numbers listed on the form

Tax-free forms (F2,F3,F5) can have multiple items per form. Tax-paid forms (F1,F4) are 1-item per form.

FWIW, I've only seen DAG successfully run FA in G3s, HK51s, and M134s. There was a guy a few years back who was trying to get it to run in a 21E - never heard if he ever got it to work... https://www.hkpro.com/threads/21e-in-florida-for-blue-ammo-testing-or-willing-tester-out-of-state.556570/

+1 on the comment above - it would def have to be converted to blowback operation as the DAG ammo has similar power to a .22. In addition to lightening the operating mass and converting to blowback from gas-operated, generating sufficient belt pulling & round stripping power will be an issue as even full power 5.56 beltfeds struggle.

Anything that is round nosed should run just fine... A lot of subguns don't feed flat-nosed ammo very well.

Sounds like a registered channel gun with a cast trunnion.

I’m kind’a confused by this story. Did the original seller sell you just a receiver without a barrel as a title 1 firearm (and your SOT added a 37mm (or 40mm?) barrel after you obtained an approved DD F1? Did the toy receiver accept a real m203 40mm barrel? Or did you purchase what you thought was a complete real Colt m203 40mm without paperwork (that was actually just a toy) and then you and your local SOT filed a DD form1 on it?
