What did you do with the originals? A Remington what? Assuming a 700, did you buy the trigger with the safety or without? Without uses the bolt stop and safety you have now.
I know I have a boltstop I do not need; I do not have a spare bolt stop spring; I might have a pair of trigger mechanism mounting pins.
Brownells sells an aftermarket bolt stop spring.
PM your mailing address, and I will send the boltstop, plus the pins if I have spares.
