Just ordered the second round of upgrades for my PCR. I previously installed the short reset kit and reduced power trigger return spring. Next, is the Reach reduction kit with dis connector,and CGW hammer. I did talk to David again and once again he went over all the parts and install procedures with me. The only downer is I will have to replace the sear since I have a bunch of rounds through the gun. I was hoping to avoid reassembling the sear cage again, maybe the second time will go easier.
