OAL for 11.5"

Hi folks,
Well, I’d like to get my Form 1 started. I’ve decided on 11.5" for the bbl length. I’m going to put on a Vltor E-MOD Enhanced stock

I’m sure some folks out there must have this set up or something similar. What should I list for OAL on the form 1? AOL is with the stock extended, right?

I just checked out Colt’s site. They state that their 11.5" Commando model is 30" when extemded. Because Vltor states that the Enhamced Modstock is an inch longer than a standard stock. I’ll list the OAL as 31".
