Does it get ship to my house or do I have to pick it up at a gun store?
David T on Sep 27, 2018
BEST ANSWER: There’s no lower on this which is the only serialized part that’s required to go thru a FFL. So it should ship straight to your door.

Great Price, Great Quality, Great Service
I ordered this product on a Monday night and it arrived the following Thursday morning. It was faster free shipping then I have received anywhere else. All the parts came in individual bags so it was easy to distinguish what parts went with what. There were no blemishes on any of the parts or the upper. Once assembled it fired and worked great. 100% recommend for first time builders.
