Your workmanship looks good enough in this photo. I am going to assume the black unit is the one you talked about making from an a2 receiver. What do you know of structural engineering??? You removed the carry handle correct??? Looks like you have also lengthened the ejector port as well. Any idea what the burst strength of your receiver is?? What is the average burst strength of a forged receiver?? What is the mil spec for this??? Are you seriously going to let a customer shoot this without knowing this???
Yes my customer is going to shoot it....guess who the customer is.....ME.
