Last fall a Western Auto Revelation 120 which is a Marlin Model 60 came my way. It had a small .22 scope on it what I found unsatisfactory for my old eyes, and I could not adjust it.
A friend has three or four Marlin Model 60 and side by side the action is the same as the Model 120. He likes his rifles. But for real accuracy he has a Ruger 10-22 with a heavy barrel, custom stock, and a good scope. I cannot compare the rifles because of the upgrades. He has many more dollars in the Ruger.
I went on line and found the manual for the Marlin 60, and followed the recommendation for cleaning. The original owner must not have believed in cleaning. The inside of the receiver was coated with hard, black gunk. In all my years I have never clean so much gunk out of a firearm. I gave it a good cleaning and lubed with Break-Free.
At the range performance was hindered by the scope, the caps were already missing and I blame myself for not replacing the scope before going to the range. I had grabbed the rifle as time filler. The primary object was to shoot a 270 and then let the barrel cool. While the barrel cooled I tried out the 22.
The 22 shot about 6 inches high and 3 to right at 50 yards and I could not adjust the scope to move the point of impact. I have since replaced the scope but I have not been back to the range. The only way I was able to move the point of impact was Kentucky windage.
I fired a few box of old Blazer 22 LR I had on hand. It was a little strange, now that I have lost my hearing I was wearing double hearing protect, foam plugs and muffs. I could hear the action function but the muzzle blast was shut out. The rifle functioned without any hang-ups to the point that I kind of like it.
I did not try the iron sights. The back sight has a very fine groove.
When I returned home I pulled the trigger group and checked out the receiver as I had when I received the rifle. There was only a couple of powder flakes in there. This indicates the rifle went thousands of rounds without cleaning. Most likely this rifles dates back to the days when shooters used 3 and one oil to lube their firearms. Marlin recommends cleaning the action approximately every 250 rounds.

I installed a one inch tube, 4x scope that came on my 30-30 Marlin years ago. I used the Lazier bore sighter and I am ready for a trip to the range.
Because of the scope issue it is hard to issue a final judgment regarding accuracy; I hope for an improvement. When I was at the range the accuracy was not on the par of Savage bolt action I had at one time or the .22 bolt action my wife bought me for Christmas 42 years ago. Nothing like an accurate .22 to get kids excited and interested in shooting.
