So I recently upgraded my norinco with a tear down and rebuild seminar with the m14 doctor. Then I purchased the Blackfeather "rs" stock, followed by a CTR buttstock, AFG and pistol grip (all magpul, tryin to do this right). And now this is where I need your help. I have a red dot sight I'd like to attach. Should I have it at the rear sight location (over the trigger) and if so, how do I do it? The blackfeather stock has no top rail. Or do I buy one of those ARMS scope mounts and have it located more forward on the rifle?
