Did you have any trouble getting your PTG bolt body to fit ? I got one and I tried it on three different guns before I found one it would work on. On the first two it would trip the trigger if you closed the bolt the whole way. It seemed the last 1/8 inch of travel was tight and that is when it would fire the trigger. I talked 5 or 6 times with their engineer and he said he had 1 other one that did that and the customer replaced the bolt handle with one of theirs and it worked. I was going to send it back out to him but I thought of trying it on one more gun and it worked.
