The largest objective on a 4x fixed power that I know of is the old 4x40mm Nikon Buckmaster.
There's little point to a fixed 4x 50mm scope, as a 4x32mm scope will let in as much or more light than your eye can use anyway (8mm exit pupil).

Poodleshooter is correct.  A 50mm objective on a 4X scope would only add cost, weight, and mounting height without providing any performance advantage.  A 50mm objective doesn't begin to offer an advantage until you get to 7X and greater magnification.

why would you even want a fixed power scope? Get like a 4-12 power with a 50mm objective if thats kind of what you're looking for.

Our military use them all the time. And I know a number of hunters that swear by them. So there must be something to them.

If I had to guess why they would use a fixed power it would probably be durability just becuase that  is one less thing you have to worry about having a problem with in the field. Or because with certain reticles you must be at a certain power in order for you to be able to range a target. Other than that It really is just the loss of a great feature.

All else being equal, fixed power scopes are more durable and hold zero better than variable scopes.  Less mechanical complexity = less to fail.
 
Also, given a variable and a fixed power scope of equal quality, the fixed power will usually have better light transmission and lighter weight due to fewer internal lens elements.  It will also usually have wider FOV than the variable when the variable is set to the same power.  Fixed power scopes are almost always more compact than a variable that includes the same magnification within its power range.
 
With a fixed power scope, you can get equal or better optical performance for less $.  If you tend to keep your variable scopes set at the same power most of the time, a fixed power makes good sense.
 
There's something to be said about keeping things simple.  Most of my rifles wear variables, but I can appreciate the simplicity of a fixed power scope.  With a fixed power, if you made the right choice in magnification to begin with, you will never find yourself in a situation where you left the scope set at the wrong magnification for a given shot, thereby potentially costing you a quick shot opportunity.
