If you are a good shadetree-gunsmith, there are quite a few tweaks that are useful in making your Marin 795 to perform better!
If not, the rifle is inexpensive & well built, so you can afford to learn a few things if you wish
Pillar Bedding is a very good place to start...but follow the directions CAREFULLY and make sure to use plenty of release compound!!
Stress-Free Pillar Bedding
Trigger Jobs work WONDERS for the feel of the trigger!!
DIP helps to shortcut some of the work with their Silver or Black Adjustable Target Trigger & Guard combos!
Marlin Rimfire Parts and Accessories
Polishing the bolt & action rails can be very beneficial!!
You could literally beat someone to death with the OEM Marlin plastic stock...but a Boyd's Laminate looks WAY better
Several styles to choose from!!
For pawn shop/gun show antiques...
Replace the buffer & action springs on older used Marlins (10+ years old) with a J&P Spring Kit...
Clean the Mag tube on Marlin 60's & varients just like a shotgun barrel...
do that & the above & your old guns will run like New!! Some better than new
