EDIT 3/8 1845 EDT: I emailed Tactical Machining to ask if this is a regular price, and folks can order them at the "3fer" price. Yes! Quoting here:
We have over 900 in de-burring right now and more in production. We will still take phone orders at 386-490-4464 and will have all those back in stock in a few days too.SiG
