I am nearly positive it will be a 20"....I can't see them selling shorties for $79. The stock pic they use is a 20"...it wasn't until the anticipation of it arriving that I found that Briklee was a paratrooper only thing.
What data do we have for full length Briklees? I would be very interested if there were any with a matching stock....for instance.
It would blow my mind if this comes with a Type 89 mount, as my current assumption was they built parts guns to their specs, and these might have just been leftovers. If it does have the mount, it will totally screw up my anticipated build...as I do have a stock cut for one, a blank with an inverted take down notch....for my 78 restoration. That stupid missing chunk of wood is the only caviat to it being 'perfect'.
The stock pic is weird looking, almost like the handguard lever has been removed....but not close enough to confirm, and the left side isn't shown....so, mount mystery.
