On my first trip to range my gas cap pin broke after 1 round. I thought that it was just a bad pin. Contacted Kel-tec and they said to send it to them. This is a brand new 2nd gen $1500 firearm. I asked if I could just replace the pin. No problem they will send me one. For insurance I ordered 2 pins and spare spring. I received my order before my replacement pin arrived. After breaking 2 more pins I started to use small screwdriver to push pin and turn cap. Today I received new cap I ordered and same thing. $25 bucks wasted. You cannot turn gas cap without breaking pin. You would think that when they assemble a firearm they would check this. From this Forum I see that I'm not the only one with this problem. Great technology, poor quality control. Also sent my CMR back for broken bolt catch, 2nd time same thing
