I have a pile of lowers sitting in my safe, I was thinking about SBRing a couple of them. I'm having trouble getting the OAL right for a few of them.
To make things simpler, to start I intend to use a Magpul CTR or B5 SOPMOD stock.
I'm trying to stay above 29" OAL to avoid any future confusion with MD laws.
So far from what I have gathered online from others who have filed Form1's it looks like the following configuration would work:
Daniel Defense MK18 10.3"
B5 SOPMOD Stock
29.25" OAL
What I'm curious about is if I decide to go with say:
Bravo Company 11.5" ( Link )
Magpul CTR or B5 SOPMOD Stock
Or say a 14.5" upper even. How can I calculate my OAL without just guessing, or just using what others say they have used online?
I don't have all the uppers, and won't for probably a few months. But I want to get things filed now since the wait is so long.
Do I really just need to be close? Is there a margin for error?
Suggestions?
