Primary Result:

Trigger Force Reduced by 0.5 lbf

 

Manufacturer advertised trigger pull values are overlaid with lines representing ruduced break values of  triggers due to the drop in module. The calculated value for a stock milspec trigger was 7.66lb and the Geissele SSA is 4.53lb. The average reduction in trigger pull was about 0.5lb, half of the calculated value. This is mostly due to unaccounted for friction. The MilSpec trigger saw a slightly higher reduction in trigger pull weight than the SSA.
