Priorities! - start with the needed, then move down the list. First up, you need mags and ammo (a metric buttload of ammo) and enough mags to make a nice scale model of the Great Wall (it's a Norc after all). Next up, a sling - get a Vickers, 'nuff said. Then look at optics, lots of good relatively inexpensive choices (Sparc, TRS25, Burris etc.) Finally, believe it or not, a whole bunch of pretty high speed guys run a vertical foregrip on a length of rail attached under the handguard, with no rail at all. If however you're hooked on a rail, the Midwest Industries Carbine length free float 2 piece that Wolverine sells is a terrific unit for about $215, no need to pull the gun apart, no removing the FSB, just cut the Delta Ring assembly off and assemble the rail onto the gun. You end up with a solid, free float rail with a continuous top rail. I had one mounted on a 14.5 Norc and it was very solid and fit with no drama, the rail length for that is 7 inches (for either 14.5 or 10.5), and you need one for a carbine length gas system.
