I really didn’t want to leave this review, but I don’t want anyone else to have the same issue I did. The first upgraded trigger I received appeared to have been printed incorrectly as it was warped in a way that would never fit in the blaster. I contacted customer service and they sent out a replacement. Unfortunately the replacement was printed the same way and would never successfully fit. It almost seems like the trigger is printed vertically and is getting compressed in the front somehow. It is a real bummer because the rev switch looks and fits great.
I reached out to CS again and hopefully the printing issue has been resolved.
I know it isn’t getting warped due to heat, since it is winter and I doubt that the trigger would warp this way due to mild temps.
