Well, I did go ahead and modify my AK and I (sort of) took my own advice. Got the Midwest Industries quad rail - even though I only really need a rail on top, the other cheaper options just didn't impress me. I did go with an inexpensive UTAC holographic red dot sight instead of the Burris, which saved me about $150. It got good reviews, and I don't figure to shoot the AK all that much anyway, so what the hell.
Heading to the range on Sunday to get it dialed in.
