Hi, guys, I want to remove the HS-Precision stock from my 10FCP-HS Precision to install a small pic rail on the forend for the bipod . How many screws do I need to remove, 2 or 3 ? Any particular procedure to install it back or secuence specs ? I need to know if I have to remove the trigger guard . I heard of 65 lbs.inch but in only 2 of the 3 screws ... (?) Since I do not want to affect the accuracy of the gun I need to know what to do . I would apreciate any insight on this ... thanks
