"G&P makes some of the nicest receiver sets out there. However, one major annoyance is that they still use the imperial threading specs for their upper receiver barrel threads. To make it fit an AEG-spec barrel nut, you’d need to rethread it properly using a Madbull rethreading tool. Alternatively, Madbull also sells G&P spec barrel nuts for some of their more popular free float rails, but these can be hard to find. Sometimes ACM rails will come with a reversible barrel nut with both imperial and AEG threads (a major convenience when available).

"FYI before you purchase this please realize that the threads are not TM spec so it requires a special barrel nut. and my friend has cracked two of these by squeezing them. DON'T SQUEEZE ANY RECEIVER PERIOD. If you do need a better grip on it to torque something down than mount it to the lower reciever with the gearbox inside. Disregard the last review as he didn't have the correct threads. Hope you learned something.

"Its an ok upper receiver if you dont mind working on makeing it fit the rest of your gun. I was kinda disappointed with it, a lot of my stock parts didn't fit. I had to put tape around the outer barrel to make it fit, and I had to chisel it so the pin would fit.
