i bought a little kit for my SkS. it comes with 10 stripper clips and a little 4x scope. now it only cost me $60 however, when i took it the the range i had problems. first i had to tighten down every last screw and replace two that were stripped out of the package. so i finally have everything secure and start shooting. using my sight at the end of the barrel as a marker. i allign the scope exactly on the grouping from my said sight on the barrel. fired 10 rounds and they were all over the place. in checking the refrence between barrel and scope, the scope is now WAYYYY off. is it common for a scope to jar loose so easily? or is this thing just a huge piece of shit. i have a feeling the store i got it from (turners outdoorsmen) isnt going to give me a refund. is there anything i might be doing incorrectly?
