I still have the 1st NP2 Gene put the trigger in.I love it but can't compare it to the stock trigger as I've never used one.
From my observations with my Trail NP2, the improvement with the Charlies CBR trigger is minor, but does improve it a bit. I originally purchased Charlies CBR for my Remington Genesis. It was a nice improvement. Main points being the lighter spring, allen screw for 1st stage adjustment, and steel pin where plastic trigger engages secondary sear. When I tried my Trail NP2 with the stock trigger, getting a decent second stage with the stock trigger was easily done with the stock adjusting screw. !st stage was a bit long. Using a drill press and tap I added my own 6/32 allen screw to the front of the trigger to shorten the 1st stage. Due to the new CBT trigger being metal, the steel pin used in the plastic CBR trigger for the contact to the sear was not needed.
I installed the SLT trigger in my NP2 this past weekend. WELL worth the $15; the accuracy I was able to obtain immediately increased by 45%.
