Hi all. Just bought a Slavia 630. Haven't had an air rifle for about 20 years, so I'm enjoying every minute of it. Anyone have any tips on tuning this model. It's pretty accurate, and I'm not really looking for any monster power increases, but smoothing it out and maybe a little more "juice" wouldn't be bad.

Thanks for any help

Welcome to the forum,

First thing id do is pull it apart and moly the internals. The slavias usually come dry from the factory and they really benefit from some moly on the spring, the guide and the sides of the piston.

The slavias are really easy to take apart and you dont need a spring compressor to put them back together. Just remove the stock, push out the pin holding the trigger, take off the trigger, UNSCREW the back end (dont just pull!) and then pull out the innards.

Don't put moly on the seal itself, just the sides!

What part of canada are you from?

Thanks for the info. I am in Winnipeg.
I have read that some people put heatshrink on the spring guide I believe.
Any thoughts on that? Any recommendations on brand of lubes to use.
This info is much appreciated.

yep you can use some heatshrink with epoxy in between the guide and the heatshrink and it should smooth it out even more.

As for moly, if you can find it, beeman m2m is good. There is also a brand that can be bought at canadian tire but im not sure what its called. Motormaster maybe?

Well,picked up some moly at CT and went to work. What an easy rifle to disassemble. Noticed that when cocked, the spring was not near binding yet so added a stainless washer in front of the stock spacer. Probably not a big difference but I figured what the heck. Lubed it and reassembled. Not as much twang as before.
Any advantage to polishing the external machined surfaces of the piston? Or do the small imperfections hold lube better and help make it smooth?

Thanks for the info webstien

The cheapo tubs of Motomaster moly have a 3% moly content.

The Beeman M2M and Macarri moly paste have a 65% content. Price is around $5USd per small coffee creamer size container. Honda moly-60 is high content too but it comes in a larger tube. Loctite sells a 65% moly but I think it comes in an 8 ounce conatiner for big dollars. High concentration moly paste is not cheap.

So, I wasted my time? Would I notice that much of a difference with the higher quality moly?

You lubed with a different product than high concentration moly paste, but if it seems smooth then you are happy. Shoot 2000 pellets and then decide if you want to upgrade the lubes again. By that time you will have "broken in" the rifle.

When Weihrauch rifles are shipped they have some sort of grease inside... not moly. They shoot fine.

Moly works great for making things very smooth and I use it for much more than the piston body and spring ends. Moly works great for the hinge pivot, cocking arm claw, cocking arm pivot, barrel detents, safety buttons, etc. It makes these metal parts very smooooth to operate.
