After reading through all 26 pages of the SBR FAQ (and giving my head adequate time to stop spinning,) I have a couple of questions on a planned build, before I send off paperwork for my first SBR.  There is a lot of discussion on whether or not an applicant can just use a range for O.A.L. and barrel length.  I'd rather not take the chance, so I'm trying to be as accurate as possible.  Please bear with me.

My proposed build:

Noveske 10.5 CQB
A2 flash hider (If this actually gets approved, My BRD Will be accompanied by an NFA  habit, so I'm already thinking ahead to a Halo or an Omni) have
Now the questions:

If the flash hider is NOT going to be permanently installed, do I factor it in the Overall Length?

If not, how much do I deduct for the part of the A2 FH not overlapping the threads?
(I thought I saw it in the FAQ, but I don't recall where.)

Of course this can all be simplified if someone already has my proposed setup and a tape measure.  help

I had a range approved for my SBR last year (approved summer 06)havent done an SBR for a while. things seem to be different now.  

for figuring my low end length, I measured from end of reciever extension to the barrel nut, then added 2 inches since TROS makes a 2" 9mm bbl

the high end of the range was 1 inch less than legal overall rifle length.

If I had to put one number, I would do the shortest realistic number I would likely build.  then in the additional description section add info as to the range or other barrel lenghts and calibers.  I dont want my paperwork to limit my imagination or addiction


dont know if that answers anything
worst case it takes a few extra days and some white-out

Measure from the muzzle (FS not included, if not permanently attached) to the butt (stock extended).  You can figure out how much to deduct for the FS by putting something in the end of the FS until it touches the muzzle, mark the location of the end of the FS, then measure.
