Many changes are yet to be made. We chopped a regular model for the prototype, yes... but once port sizes and other things are right, we will be turning custom uppers for them. We want the vent holes to be positioned differently and to look like less of a hack-job. This is only the first prototype... Much will change.
Alright, I'm guessing this prototype isn't just out there floating in some random shop, so the picture is likely at RA HQ which means there's a good chance the man behind the poster is likely in the SLC area.
I'm going to take a risk here and say he was in attendance at the recent March 1 XCR shoot.
Now, assuming this person isn't leading us astray by telling us he's not affiliated with RA, I'll venture a guess that the true identity of silentpill is in fact....
