Should these handle a 44mm scope?
That depends on the gun, most of the time, it's better to go with high rings if you're using a scope with a 44mm objective lens or larger
Are these rings tall enough to mount my Hawke 6-24X56 scope on my Mrod field target rifle?
I would go for high rings
New owner of a mrod.25 and for the life of me can't find where to put the stop pin or do you?
You don't use the stop pin on PCPs. Not needed
What is the saddle height of this ring?
It is 14mm from base to bottom of ring.
will this ring accommodate a 44 mm objective lens?
With a UTG 3-12x44AO (SCP3-U312AOIEW side focus) on my generic Titan, these rings give me .024" clearance. Without the rubber dust cover I have .120", which I mention since the cover can be sanded down if needed, like if shimming the scope. That scopes bell is 2.09". Fyi.
Depends on what gun you are mounting the scope on. If it has a raised rail it shouldn't be a problem. If it is directly grooved then it will be cutting it close, a high profile may be a better choice.
will these fit a 11mm rail?
Yes. The Leapers/UTG mounts are made so that one side of the portion you tighten onto the rail is 3/8" and the other is 11mm.
