Propmahn, actually on your muzzle brake question: I beleive the AK-74 has the best muzzle brake. I watched some shoe on TV about them, and when the guy was shooting the AK-47 and M-4 the muzzle rise was a lot. Now he pulled out the AK-74 and hardly any rise at all. It was a good show on the Discovery Ch or History Ch about the life and times of the AK-47.
