Pof drop in trigger - POF USA Trigger System 5.56/.223 Remington Drop In 4.5 LB

It is a great product from POF. I have several of their rifles and this trigger is equal in quality as all there other products. There is one concern that made me rate it with only 4 stars. Do to the slight differences in lowers from their lower and my old Bushmaster, you can turn the safety on the safe position even if you have the hammered dropper. This doesn't happen in any of my Mil Spec triggers or my Geisseli Triggers. it still work correctly when the hammer is cocked and you put the safety on. you could stand on the trigger and it will not fall when the selector is on safe so it is safe. The only other issue is the KNS pins that come with it. my receiver must be a little thinner on the Bushmaster than a POF lower so ther is some space between the pins and the receiver but that's not to bad if the thread tight in the pins holds as they always do.
