To be honest, I really don't know at this point. I have had two range sessions with it, using the takedown case for transport to and from the range both times. After the intial sighting in at 50 yards on the first trip, it held its zero for the second trip. That's with me shooting the open sights. I took the scope off (wonderful claw mounting system by Duane) and haven't put it back on yet.

The takedown system and lock up is very positive. I don't think it could vary hardly enough to tell, at least not at ranges this rifle will be used for. It has a very positive stop and metal mating faces. The lockup lever and screw are strong are have zero play.

But... I haven't shot it enough to make any great statements of fact.
