Form 1 SBR: what caliber are your registering

[Reptile]

It’s my understanding that in Mass, only .22 is legal on an AR15 lower.

Are people registering 5.56?

Registering with who? You can’t FA-10 an SBR.

I mean when you fill out your form 1.

Then once you get your stamp are you FA10 the SBR in Mass?

 

[Gasgunner]

The system won’t let you submit a rifle with a barrel less than 16”. They’re un-FA10-able.

If it can’t be FA-10’d, it doesn’t matter what caliber you put on the Form 1.

Just put 5.56mm or .223 and move on with your life. You're overthinking this.

 

[LuvDog]

put whatever caliber you are going to shoot out of it.

So SBR's don't get an FA-10 in MA. And that's g2g?

Can't eFA-10 an SBR as a rifle because it won't let you put in anything less than 16 inches for the barrel.

Register before you Form 1 it and it's no problem--it's a rifle with a 16" barrel or whatever you want. If you decide to do it post barrel chop you will need to register as a pistol or "firearm," I believe.

 

[Gasgunner]

You SBR it so you don’t have to FA-10 it. Why would you volunteer info to the state? Their system doesn’t accept SBRs that’s their problem not yours.

 

[andy t]

I just put whatever is already on the lower.

General thought on temporary changes is that they're fine (Federally) as long as you can always return the rifle to configuration listed on the tax stamp. So if you own one 11" upper in 5.56, that is the configuration you list for all your Form-1s.

Just dug through my files; all my ARs were submitted as "5.56NATO", same as marked on the lower.

If you already know you will be using different uppers, you can list those lengths and calibers in box 4h (Additional Description).
