AK's do not lock open. It's an AK47 not a AR15. Like another poster said go to AR15.com and go to the AK section. Start doing allot of reading and you will learn all you need about this awesome rifle. The Wasr's aren't the greatest but they serve their purpose. I prefer the Mak90's, russians, non WASR Romainian and the polish AK's. Buy a parts kit and build your own AK. It's legal in most states.
