Is this kit legal for the state of CT?
Michael M on May 18, 2019
BEST ANSWER: I have personally not seen any legal issues with just the parts kit. Leg issues normally arise with magazine capacity, ammo, barrels and suppressors. If you can purchase the lower in CT you can gets the parts.
What else do I need to complete the upper receiver?

Great company, great products and great prices.
I've compared the quality next to my Colt LE6920 and my Smith and Wesson M&P Sport 2 and found no difference. Accuracy was also identical to the other two. I even mixed parts from all three, with no change in performance. PSA is a great company, with a quality product at a great price.
