    Great Receiver for a Great Price

    Posted by Unknown on Oct 4th 2022

    I was able to pick up my receiver from my local FFL in just over a week from the time I placed my order online. This is a great receiver and the price was fantastic. Anyone looking for a high quality ambidextrous lower receiver should definitely give this one a chance.
