I am preparing to equip my 788 "Scout Rifle" of my own design, with a shooting sling. Probably a TAB. I shoot RH. I am wondering how many and at what locations should I install flush cups. Also, if there is a Post or link to proper installation techniques, I could use that info. I plan on accur-glassing or epoxying the cups in, unless instructed otherwise. The stock is the only synth. on the market that I am aware of....dare I say, a Ram-Line. Any info,tips, etc...is appreciated.
