E-File 5320.23 and Form 1

[electronman1729]

Doing a form 1 on efile for a AR lower. The drop downs only let me do "5.56mm" for the caliber. Would I put the same in ("5.56mm") for the 5320.23?. In the olden days I would put 5.56x45mm.

Thanks

My form one said 5.56 x 45 for the SCAR but chose the 5.56 mm button when filing and I had no issues

Ended up just putting the caliber size and left out cartridge size we will see what happens.

My previous SBR that I sent in 2016 I just wrote 5.56 on the form. I write whatever is on the firearm. No issues with that one either
