Twice now, Jeff at CMMG has disassembled new gun parts/assemblies for me at KC gunshows when I needed just one part and not the entire assembly.
The first time was as easy, but totally within his right to not do, as removing a charging handle from a new upper in order to sell it to me. Also, on that trip I had said (on here) that I was coming to the show to buy a few things such as a stripped receiver, LPK, charging handle, etc, and proceeded to list them out in a message. When I arrived at their table at the show I inquired about stripped lower receivers and he said they were completely sold out. Bummer.
But then Jeff asked "Hey, are you Eric?" Yes I am, I replied. "I have one saved for you. It's not a seperate receiver and LPK (it was already assembled by them) but I'll sell it to you for just the price of the receiver and the LPK." (BTW, they charge a few bucks more to assemble a lower for you.) I of course accepted his gracious offer and thanked him.
This last time involved removing a new A2 metal buttplate from a new complete A2 buttstock assembly, in order to sell me just that one part that I needed.
Jeff and CMMG have well earned respect from me and I will continue to buy from them whenever I can. Thanks guys!
Eric
