Re: Sendero trigger
Take a look at the Shilen Standard Trigger. I've used many on customer rifles and , one of my own old Remington Varmint Master (custom barreled in .22/.250 AI). Adjustable from 3 1/2 to 1 1/2 lbs. pull weight, fully adjustable for 'creep' (sear engagement) and over travel. I always keep some in the shop, a popular item in this part of the world.
