The tech sights are worth the money. You want some form of easy adjustment, so tech sights, some other target sight, or an optic of some form.
I loved Model 60's until Project Appleseed, then I realized I have better options than putting my hand in front of the muzzle to reload when I am tired and lying in the dirt next to newbies. I have two Marlin 795's as loaners, and a Marlin 7000T which I love so much I have a second still in the box in the safe. They all use the Marlin 60 receiver.
Marlin 60 tip 1: McDonald's straws are large enough for shakes, which makes them large enough for .22 LR speed loader use. Fill it up with with one end pinched off, and you can pour them into your tube.
Marlin cleaning.
The Marlin micro groove rifling runs best never being cleaned and only using lead bullets (no copper flash). The chamber still needs a good scrubbing. You need an old school .22 LR bore brush, and either a regular chunk of cleaning rod (okayish) or something made from steel cable like a roll up cleaning rod (better). You need something that can transmit torque, even if only a little, and it needs to bend. With a rigid rod you end up bending the brush which wears it out faster, but brushes are dirt cheap.
Take the gun down (out of the stock) and remove the bolt. Come in as straight as you can and put the brush a case length into the bore and twist it a bunch. you can wrap a little bit of patch around the brush to help hold solvent and gunk.
What is happening is enough gunk builds up in the chamber to start sticking to the cases during extraction. This is just like having gunk on the bolt, but worse. Only using copper flashed bullets can eliminate a lot of the problems, but the rifling is not made to take it and the rifling doesn't work as well with it. Regular exposed lead .22 LR is outside lubed with parafin (really good stuff uses bee's wax, which is messier but less sticky). The bullet rides the bore during loading, so the chamber gets a wax buildup. The readily available solvents are generally not good at dealing with wax, so the wax gets left in the chamber. Clean it out and you should be good for a whopping 200 rounds instead of 100. That is enough to let you clean in the evening after the first day of shooting and be good for the next day. If you have been cleaning like that and you still have issues, step up to bee's wax on the bullets. I recommend that anyway, as there is little point learning the limits of your current ability with lousy ammo.
Here is a good reference article with lots of ammo names. All rifles are different, with some liking one ammo more than another, but you can still get an idea of what different ammo types will do and names to look for, if you can even find anything. On the plus side, quality ammo is rarely hit hard, price wise, by a quick ammo scare. Covid is different. Budget about $80 - $120 for a brick, is my recommendation. You will still learn a lot with cheap ammo, but it will be harder to learn and you won't learn as much. The feedback you get from good ammo is just like the feedback you get from good steering.
Edit: No really here is an article...
