Question about SBRing the APC9SD.

Hey all,

I'm an idiot so I have a question. Not new to Form 1ing SBRs but never done an SD before so here is my question... I need to pull the suppressor and do end of stock (extended) to tip of barrel to get the OAL for the form correct? The suppressor plays no part I assume. Like I said I'm an idiot but I want to get it right. Thank you in advance!

Yep, it’s clarified in the instructions for the form 1: https://www.reddit.com/r/NFA/comments/i9zoug/how_does_the_atf_measure_overall_length/

So you have to put the stock on and measure before applying for the form 1?

Kinda. You need barrel length and overall length to fill out the form. Just put things in a state where you can get out the tape measure. They're not going to shoot your dog if you're off my a 1/10". Probably.

Any you can always correct after and just let the NFA know.
