hello, my tapco stock just came for my sks, it does not have a rail on the bottem like my 22 ruger tapco stock, i boght a foregrip at a gunshow and it comes with a rail, ncs star , in front of the mag i have enough room for half of the rail, so i can cut it in half, i have a tap kit and every thing and with enough help from my friends i can put it on , i was just wondering if anyone else has done this with a tapco , are they too cheap to start drilling in two holes , please give me any and all imput before i go and do this in 10 minutes, thanks
