I trusted the drop down and got denied after 63 GD days.

So help me out, what model is this? Calguns.net?

The bear and star emblem is on the California state flag.

87% of the time, any question starting with "Why..." is answered with "Money."

I am so tempted to lay down the melancholy burden of sanity...

Indeed, but I don't think I can upload that for a model number

At any rate, that's the joke. A California lower turned into an SBR.

AR15...which in restropect I...get...I guess...now that I understand how little common sense the beurcrats at the ATF have.
Reading the instructions more carefully, it obviously has to match exactly...well, the only thing that matches exactly is "CALGUNS.NET" which seems silly, but what else can I put?

Yes, I would use calguns.net.
I am no expert though.

My only SBR is a Mega lower and the model was "Gator"

That's funny, I just submitted my 2 Gator Form 1s too. I love those old Mega lowers.

Resubmitting with CALGUNS.NET...it's the only option I guess. So dumb. Of course I got a warning that it could be delayed since I'm entering a new model name.

What's the manufacturer's name, I assume engraved elsewhere?

Based on your picture, there might be no model designation, and thus you would use "N/A".  The "calguns.net" may just be a cosmetic engraving.  It would be good to know what the manufacturer used for the original designation.

Any idea what the model number was on the 4473 when you bought it?

I didn't even think NA was an option...
The manufacturer is Kaiser Defense

Show Your Work: The Logic

When you fill out a Form 1, the ATF doesn't care what you call the gun; they care about what is actually engraved on the receiver. Since your lower doesn't have a distinct "MOD" or "MODEL" line, the primary branding acts as the model designation.

Manufacturer Verification: You confirmed Kaiser Defense (San Diego, CA). This is the licensed entity that filed the original manufacturing notice.

Model Identification: In the "OLL" (Off-List Lower) era (circa 2008–2010), Kaiser Defense produced these group-buy receivers for the Calguns community. Because they didn't stamp "KR7" or "KR5" on these specific units, they registered the model name with the ATF to match the engraving.

Regulatory Record: The Canadian Gazette (SOR/2020-96)—which uses the same manufacturer/model data as the US ATF for its "Assault Weapon" ban lists—explicitly categorizes these as:

Manufacturer: Kaiser Defense * Model: Calguns.Net 4.  The "OLL" Trap: Many people mistake OLL for the model because it stands for "Off-List Lower." However, on your receiver, OLL is the serial number prefix. If you put "OLL" as the model, your Form 1 will be rejected for "Model Mismatch."

My Confidence Level: 95%

I am 95% certain that CALGUNS.NET is the correct model name for your Form 1.

Why not 100%? There is a 5% "ATF Chaos Factor." Very early Kaiser runs were sometimes logged as CALGUNS (without the .net). However, since your engraving explicitly says CALGUNS.NET, the modern eForms instruction is to type exactly what you see. If you select "Kaiser Defense" and CALGUNS.NET appears in the drop-down, select it. If it doesn't, select "My item is not in the list" and type it exactly as it appears on your magwell.

Final Verification for your Form 1:

Manufacturer: Kaiser Defense

Model: CALGUNS.NET

Serial: OLL-0654

Interesting history there, I'll give calguns.net a shot and see what happens.
Thanks for the input
