Sounds like you have a fun project. I was looking into doing the Area 419 conversions and stopped after I was calculating all the muzzle brakes I'd have to buy and sell... turned me off!!!!
Zak at TBAC told me at SHOT to send in my older TBAC cans to be recored with the new Ultra gen 2 stuff, but other things have kept my cash busy, like finding powder and bullets! I did pick up an AUG randomly and it has been a blast.
Now I'm selling my Raptor, which I love to get something to tow more lbs and fit 4 crazy kids and their mom.
I'll have to post my MRAD , just got a 400 Norma barrel, working on some loads right now
