I just hafta commend the guy 22synrodn/triggertreat for coming up with this mod! Did it to both my .22 and .30 which were both having problems with cocking and the .30 was so bad it was jammed. All I did was this mod didn't change anything else and now they both cock as smooth as butter! If you have the means to do so I highly recommend it. I haven't checked my tunes yet but is supposed to really tighten ES and SD as well.

"In my view, the biggest problem with the mechanics of the Marauder and other similar guns is hammer drag. I’ve been trying to find a better way to limit this drag in my DIY SSG and have found a simple, DIY way to do this and have decided to share my idea with others.
I introduce to you the F.A.M.E mod which stands for Friction Assist Marauder Enhancement.
My idea lifts the rear of the hammer up and off the air tube which drastically reduces the friction/drag between the two and eliminates galling. I find my strings are more uniform and the cocking effort much easier and smoother. Also dirt and dust does not affect the hammer nearly as much or as often. My ES and SD numbers have dropped a considerable amount as well.
You can hone the air tube and polish the hammer but still can’t eliminate as much drag as this mod can. The washer sliding on the top of the air tube has far less friction than the hammer to air tube friction. The 1/4" tubing keeps the hammer centered and off the sides of the metal slot further reducing drag.
Another benefit is that the power hungry shooters among us can have increased spring ratings and still have reasonable or at least doable cocking effort.
Here is a comparison of two very similar tunes with and without the mod and shows how much more uniform the mod makes the string:
Here is a top view of the F.A.M.E mod installed in my Internal DIY SSG setup. I’ve been using this mod on and off for quite some time now and the differences are very evident to me. So much so that I don’t want to tune without it. The nylon spacer on the end of the bolt is not part of the F.A.M.E mod but is another mod I added to the DIY SSG to reduce rebound noise from the bolt hitting the gap adjuster.
Here are more details and the parts needed to do the mod:
Here is the mod to the breech needed to clear space for the washer to slide. You only need to remove just enough of the slot to allow for the thickness and width of the washer used. You can substitute the steel washer for a brass or bronze one that may slide better and last longer.
If you’re just curious is to how much drag reduction this will give you, you can do a quick test by installing the 1/4” tubing and washer to the hammer lug, tuning it correctly and running your hammer back and forth to feel the difference it makes before trimming the breech. I think you will be pleasantly surprised at the difference as I was when testing it for the first time."
