I have a SA that I want bottom metal for. The screw spacing is 4.42" near as I can tell. All I have is the receiver, bolt and trigger. There is no bolt release lever along the side of the receiver, so I'm guessing this is a bottom bolt release. Is this the correct bottom metal??

Are there other (cheaper) options out there?
