This is a great piece for putting modern scopes and rings on your Marlin 336. Several other reviewers commented on the front mounting screw being too long and extending to hit the bolt. That is not a problem on the rail I received. The front screw hole is not counter sunk as much as the other three holes, so the screw cannot extend into the bolt area.

I'm very pleased with the rail. If you use see through rings, you probably won't be able to use your open sights. I'm changing from see through rings to lower rings to get a better cheek weld. The Marlin stock is setup for a low cheek weld for use of the open sights; so lower rings should improve accuracy by minimizing the rifle tilt that you can get with the very high see through rings. Still deciding on permanent or QD rings. Leaning toward the QD rings in case I want to pop of the scope and use the open sights.
