According to Olympic Arms, their standard "USGI" single-stage FCG yields a trigger pull between 4.5 lb and 7.5 lb, and you can specify a trigger job for 4.5 lb pull for a fee.

Does anyone have pics of the Olympic Arms trigger and hammer, or know how they can get below 7 lb using standard springs?

I have a RRA FCG and DPMS FCG, both yield 7.5 lb trigger pull w/ standard springs. If I switched to the Olympic Arms trigger and hammer, will I get less than 7.5 lb pull? Or should I just shoot the darn things and let it wear in over time to get a lighter pull?
