This was posted elsewhere, but I didn't want to hijack that thread, so here we go: Like the title says, will this Bergara B14R trigger mod work for the BMR?
There's a very easy to do mod for the stock trigger, it's almost as if Bergara intended this... https://www.rimfirecentral.com/forums/showthread.php?t=1219859 If this doesn't float your boat, the B14R is compatible with Remington 700 triggers. A lot of people use TriggerTech Diamond triggers, I use a Jewell HVR.
