Hey everyone,
Just a followup to my previous post. I received the KSC Magnesium Bolt, and KSC Metal Upper Receiver in the mail from DenTrinity today, and it fits in my HFC M11A1 like a glove! It fits perfectly
So the HFC M11A1/Team SD-203 M11A1 is fully upgradable with KWA and KSC parts, contrary to what the different M11A1 makers may tell you. they are all the same gun, and parts are fully interchangable. I've also tried KWA Mags in my HFC M11A1, and they work as well
