Keith I honestly don't think I've owned a nicer gun similar.
It came with a hand signed tag of the one person that built it.
Like a Shelby motor.
I bench rested it when sighting in the rds. I know it's a short distance of 25yds but the group was laughably small.
I was giddy. I'll be hitting the plates at 300 easy with it.
And the NFA letter is dated from February, three months before I bought it. There are several KAC serial numbers on it so its apparent the seller had intent on P/W something for the future buyers down the road.
Sent in on Feb and received back in June so it was a bit quicker but not instant like you think.
