Since this is a stripped lower this can be shipped to california as an FFL and treated as a long gun?
Ahman M on Jun 10, 2018
BEST ANSWER: It can be shipped to California, however it is put in an ‘other’ category and can only be sold to ages 21+ if that is your concern. It can be built into a long gun, and then an intrafamilial transfer can be done to someone under 21. It is not treated as a long gun until it is built into one.

Will this work with the PSA classic Blackhawk lower build kit?
Billy H on Jun 15, 2018
BEST ANSWER: I have used several Blackhawk lower build kits on PSA stripped lowers and have been very pleased. The only improvement I would suggest is to upgrade the trigger assembly with one of PSA's enhanced units down the road, they are sweet. The trigger system that comes with the lower parts kit is also a good working unit.

Great product at an excellent price!
First, I would definitely recommend this PSA Lower receiver. This is my third build using a PSA AR15 Lower Receiver. It is a basic mil-spec receiver and the quality is excellent. Fit and finish is second to none, and it's at an excellent price. This receiver is not just for budget builds as indicated by the photo of my .223 wylde.
