Hey guys, my name is victor and im 18. im from AZ, and i have a Yugo SKS. my uncle bought it for me 2 years ago as a stating rifle. i now want to get into more serious shooting,like longer distances. i want to start with building a whole upper first. i found this Upper Receiver at cheaperthandirt.com and i was wondering if you guys could give me your opinions on it, and maybe some advice about building my AR. Thanks.
