Not 3.5 lb trigger pull - RISE Armament RA-140 Super Sporting Trigger

We have 10 of these triggers in milspec AR15 M4's. The pull weight, if measured in the middle of trigger where your finger will naturally rest, averages just under 5lbs. Contact RISE the mfr and they will state they measure trigger pull of 3.5 lbs at the bottom end of trigger. Other than this the trigger has a nice pull quality. Unfortunately the housing is a bit long so it may not work in AR308 of DPMS Gen 1 design. Also, the set screws when tightened altered the trigger pull heavier. So we were forced to get the KMS pins. In consideration of these factors the price isn't all that great.
