I did think about the "instant gratification" route, and at these stock prices you and bigdog listed $800-$1,000, but like you said, the initial investment is steep, and then hassle of locating a buyer, but may be my only option that makes sense. Hate to pay for half an M4 and only get like 2% of the parts ordering just the stock.
I have done research on the 922r for these some, I read the FFT Trigger pack was 3 points and lighter trigger pull, I was thinking of building a new trigger pack from all the US parts I could in the A&S Trigger Frame, that way if I mess it up I still have the factory Unit as a backup if I need to revert back. So that would be 4, the mag tube (read good things about SOCOMguy tubes) and USA follower. Which I would be at 6 total compliancy parts. Plus there are the handrails and such.
Is there a way to get the 14" barrel as a civilian to Form1 a SBS? I could do that with the second M4 if I go that route.
