It is the terrible tolerances that DP has in their markers that leads to problems. I love my G3, but I have seen more than a few that were constant trouble makers and I have seen many of the guns measure out different between like models. My techt bolt works fine in my current G3, but my friends only liked the stock bolt and had issues with a techt kit. As mentioned get ahold of Yoda on here or give their Facebook a try. I have had good luck corresponding with them on there and they are good guys to work with.
