50mm at least.I have found that with a 50mm objective you will need a minimum of high scope rings.Most medium hight scope rings will not give you the clearance needed for a 50mm scope objective.
Being that the obj.is 50mm,I would put on a pair of 1in.high rings.
Scope rings are used in mounting scopes on guns and rifles. Scope rings can be purchased from several retailers as well as on several online websites.
Assuming that your scope is a 3x9x40 scope,then medium height rings will do the job.If it is a 3x9x50mm scope,then you will need a set of high scope rings.

While anything is possible,why would you want to use a scope of that power and objective size on a .22 cal.rifle?If your receiver has a built in 3/8in receiver rail then you may be hard pressed to find rings of the significant height to mount a scope of that size.I would recommend that you get a scope of 4X power.That is all that is needed for the maximum affect range of a .22cal rifle.

It all depends on the Daisy Scope rings that you have. The M4 has a removable front and rear sight. This will allow you to add a scope to the Weaver rail mount on the M4 if your scope rings are the weaver size. If not, then you need to purchase weaver scope rings for your scope.
Maybe. Question is if the bell of the objective lens will clear the barrel when mounted. Some will, some won't. Other than that, If the size of the tube of the 2 scopes is the same, and the objective is clear of the barrel, you should be OK.
All else being equal, yes.
It is: 50mm = 5cm
