Howdy folks! I've got a 2 pc 20moa base for a rem700 that I've had for a long time. So long in fact that I can't remember if its for a long or short action. I'm pretty sure its a nightforce. It is a picatinny type and is black with no markings. I can post pics tonight afterwork. Is there a way to. Tell which it would be for? I don't have access to a short action to put it on. Thanks for the help!
