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.

Alton H on Apr 19, 2018

Is this a rifle lower or can it be used for a pistol build?
J R on May 13, 2018
BEST ANSWER: Any lower regardless of the markings can be used as a pistol lower...the law states that if you buy a complete rifle you can not use that lower for a pistol.

Can i use this with the 9mm hybrid uppers from PSA if i used a 9mm lower PSA kit and had a magwell conversion for glock mags?
Block on Nov 8, 2018
BEST ANSWER: Yes, be aware sometimes there are figment issues with conversion kits and require some Gunsmithing> personally I would stay away from conversions and get the correct lower that accepts 9mm Glock magazines. I am a gun store owner and gunsmith, I am giving my opinion from past experiences.

works fine
Bought one of these to assemble a PSA carbine kit. Uppwer half was already assembled. Less than an hour to assemble lower, including running upstairs numerous times to check a YT assembly video. PSA puts the parts in different baggies and makes it easy. The parts you need for a step will be in one baggie. Rifle runs great. About $335 without optic or rear sight. Even has a nitrided barrel. Lower mated up perfectly and colors match (every company's black is not the same). What a deal.
February 16, 2019
Very good lower for the price. Everything you need to build a quality AR. My 10.5" pistol build went great. I'll definitely be doing another PSA build in the future.

Anodizing is light
The lower I received will not match up with any upper I have, not even a PSA upper. It is more of dark gray than black. Not a fan of 2-tone guns. Haven't even built on it yet so don't know how the function will be.
February 13, 2019
Was easy to build. Great company
Was shipped quickly, FDA transfers went as planned. Fit and finish were as expected
