Archived [ARCHIVED THREAD] - When you SBR an AR lower, what dimensions do you input on the form 1?
Posted: 2/2/2022 11:40:50 PM EDT
So far I've only SBR'd my SP5 and SP5k PDW and I used the specs off the Hk website, but a lower being just a lower with infinite possibilities to customize with the uppers what am I supposed to input?

ETA - form 1, not 4.

If you’re using a Form 4, it’s an existing NFA weapon…

Assuming you mean a Form 1, you put what you intend to build. It’s really not that difficult.

That would be a reasonable number. Barrel length + 19” works for the AR platform.
