This is a great trigger. i think that the stock trigger on the new trixs are lacking. tehy dont have exterior adjustments, and arent that adjustable. this has an external adjustment point, can be shorter, and is very smooth. it also has very littel side to side play. after shooting teh guys proto i tested, it was much much faster than my freinds stock proto. teh trigger was lighter too.
Conclusion:
All around good trigger. i havent really tested too many proto triggers so i dont know how it stands up to otehrs, but its a good one.
