I have a 4.275" spacing model 11 in .223 that I am converting to 220 Swift with a 112 J barrel. I acquired a cheapy factory black plastic stock from Numrich on E bay that fits perfect. It was listed as a mod 10 but on the packing list it is labeled as a 110 stock. I am in need of a stagger feed mag box, spring, and follower assembly and I am not sure exactly what part # I need or how to source it best. The second part I am in need of is the front gas baffle that isn't extended to limit rearward bolt travel and I assume it to be the std. 110 long action baffle Savage part # 103322. I was over whelmed when I looked at all the choices on Numrich. I would sure appreciate any help you can provide as the rifle is ready punch holes in coyotes as soon as I find these items . THANKS!!!
