Really high quality upper receiver. I definitely would recommend this to anyone who’s looking for a really nice, Carry handle pistol build.
Also, this part is not about the receiver, but about the customer service. The customer service at this company is beyond amazing.. They really go beyond making sure that your order is protected and that no one is misusing anyone else’s credit or debit cards. Thank you
