I just spoke with a local gun smith to see how much it would cost it install a Timny Trigger on Remington 700. All he would have to do is take the X-Mark Pro Trigger out and drop the Timny in. I was told it would cost a few hundred dollars to do the job. What I don’t understand is timny 520 trigger drops right in and can be adjusted with a hex key and a trigger pull gage. I was told the adjustment is what brings the price up. Is this the normal price for a job like this ? Ps....I have all the parts needed no parts would be from the gunsmith.
