i'm asking another AK question again. sorry if i'm anoying everyone but i'm just looking at my options for an ak. i've seen a few bulgarian sa-93s and they look like they would be a good base for me to build a russian type III clone. all i need is to install a gas block and FSB so i can have a cleaning rod a bayo but i'll have a smith do that later, it's not that important to me right now but installing a conventional stock is. sa-93s have no lower tang and my question is how much would it cost for me to have a smith install one or would it be easier for me to do it at home?
