Gamo Magnum Gen3i scope size

I am looking at getting a new scope for my Gamo Magnum Swarm Gen3i and I reached out to a couple vendors asking on a reliable budget scope for the magnum gas piston gun recoil. I was recommended the UTG or any 30mm tube Hawke. I am wondering what is the max size scope you can run before the magazine interferes with the sight picture. I like the UTG in 3-12x44 but am wondering if the 44 will be too large to clear the view of the magazine mechanism. If you have any recommendations on scopes as well. I am looking for something under $200 and preferrable with parallax down to 10 yards adjustable and with mil dot reticle adjusting for pellet trajectory at range. I am looking a minimum of 3-9 power as some shots are closer so need the 3 power for those and like the ability to crank it close for a clear sight picture as well. The stock scope works ok but there is no parallax adjustment so it gets blurry when using anything above 6 power at ranges under 50 yards or so. Most my shots are well under 50 yards. Plus I want some mil dots as I have a scope on a gamo urban that has mil dot reticle and it is a huge improvement in my mind over stock crosshairs making easy windage and trajectory adjustments.
 
One to at least consider, springer rated, under $100 and rings are included. I own one and although early yet, seems to be holding up well.
The Hammers line would be another. You can find them on Amazon in various sizes, also under $100. They come with a 1 pirece mount but not sure how that would work if your rifle has the RRR scope rail.

Awesome thank you. I just reached out to a vendor that I had purchased another airgun from asking because I had bought a Mantis scope from them and liked it on the PCP and asked if it would work on there and hold up to the magnum recoil and they recommended a few other options that would last longer and be more durable that they had.

Which scopes did they recommend? I'm looking to replace the stock scope on my gen3. I would like to at least have mil dots. thx
