So I bought this upper off another CGer without really looking at it as I wad in a hurry at the time. I assumed I was buying a factory side charging upper but it's actually a standard S&W upper with a channel dremelled into the left side. Now i doubt this will work for a couple reasons: the channel is not level and the bolt handle would hit the bolt release when cycling (see picture). Also, I'm new to side charging, but isn't the charging handle usually located on the right side, not the left?
Basically, my question is: is there any way this could work, because I don't see it.
