So I got the nylon washers from DigiKey. Great place for electronics parts, BTW.

Per my calipers they are .56mm thick. I had to reduce them to .40mm thick in order for the cocking bolt to be able to fully push back in. Since it is nylon, that was easy, just put the washer on a piece of sandpaper and used a finger to rub it back and forth.

However, it didn't help smooth pellet loading completely, since there's still a lot of extra 'lip' due to the curviness of the breech. Did it help? I like to think so. See pics. I do know that Crosman now sells steel breaches with a hidden breech screw, don't know why they put the screw in its original spot.

BEFORE, AFTER, and the breech Screw and washer pics are shown below.

It is kinda neat.
The screws are plastic (They have got to go).
But I like it..

I've gotten brass, nylon, and steel shim stock washers off of eBay over time, primarily to fix the trigger wobble on the Crosman 2240. Knowing the specs you want, you should probably continue your search - I get around 50 for $3 delivered of standard metric washer stock. Advertise sizes starting at M2 and going up.

I have a similar one on my 1077 - believe it's a Gamo. Laser holds the zero real well, and the flashlight is decent out to about 15 yards. I'll have to get it out of the safe to take a look at the mount.

I have my (new to me) PRod and am it getting outfitted the way I want it.
I had a combination flashlight/laser on one of my Marauder rifles and thought I would like it on the PRod.
I found a clamp (ebay) that clamps onto the air tube.
It has rubber inside to protect the tube and prevent sliding.
It uses thumbscrews though.
I would like an Allen head or TORX.
Looks good…

Many years ago, I bought a package of these screws.  They are slightly over sized, but it is easy to chuck them into a drill and use a file to fit them exactly to the breech.

I have seen thin brass washers that may work.

Why don't you just take the metal washer and sand it down thinner? ???

Thanks but the washers are TINY and hard steel. I don't have the tools to do sanding work on something that's the size of a wristwatch part. It was hard enough enlarging the hole 1/64" or so with a Dremel conical diamond grinding bit, they kept flying off and joining the socks that disappear in the dryer :).
