    Good Upper

    Posted by Ray F. on 8th Mar 2024

    When I was planning my PCC build, I decided to use MP5 magazines and wasn’t aware that the by choosing the MP5 magazine, I would have a stumbling block. I initially used a different upper and when attempting to get. MP5 mag to lock in, I discovered the initial upper would not fit correctly. I went back to NFA and read up on their C5 upper and noted that the MP5 mags would fit. Once I received the upper, my build was finally done. Great product. My fault for not doing a complete research but I am very pleased now.
