    M4 upper

    Can’t say enough about the quality of people assembling these quality parts. I don’t know any of them personally but with all the research I put into my purchase, it’s obvious these guys care greatly about the customer and the product they provide. I found zero negative feedback on Andro. Great prices, great service, and a great product.
