The reason I ask is because I have a chinese sks with a tapco stock on it, with tapco mags. Brought it out to the range the other day and the magazine fits nice and snug into the stock. Problem is loading the first round into the chamber i have to hit it with the charging handle two or three times in order to get the first round in. Once that round is in there is no problem with the remaining four rounds being jammed at all. So wondering if someone could help shed some light on the issue and their opinion between the two magazine manufacturers.
