PCP hammer lube and the Franken-rod

signal3 · Mar 30, 2019

The .25 Marauder: Installed a Hill max performance matched parts kit some time back. Today installed the JSAR side cocking breech, aluminum tube, and mds hammer. Hill included a graphite powder for lube. This works quite well but when disassembling today I became concerned that fine particles may enter the valve through any gap that may exist between the valve stem and valve. Hill hammer is a lightweight aluminum. When assembling with the MDS hammer I used a PTFE dry lube instead of the graphite. I ran two magazines and all seems well. What lube do you use for PCP hammers...specifically MDS sleeved hammers?

Franken-rod:

What do you think about the side lever action?

Of my two main line guns, I far prefer the feel and touch of the side lever vs. the bolt.

I don't use lube with MDS hammers, its unnecessary. I run mine dry. Nice looking build, just need a custom barrel band!

Oh yes! The side cocking is so much easier and intuitive given the location just above the trigger.

Nice build!

This is what I use/used on all mrods and WAR guns I owned just spray the inside of the tube right before you put the hammer in and let it dry. That way there's no particles from powdered graphite. Goes on wet and drys fast with a nice think film. But like Matt said not a necessity with an MDS hammer but I still do it and usually where the bolt rides as well.

Cool. Yep, I found out after-the-fact that the JSAR breech is just a bit taller than stock. I asked JSAR for a band...they indicate may consider it. It looks unfinished without one.

Oh I like! I will get a can...Good reviews on AMZN.

Wow, very nice!!

Thank you. The modified Armada stock reduced weight by 8 oz,, the aluminum tube 23 oz, and the shorter shroud almost a half ounce. The shorter shroud still holds two baffles. Of course the moderator adds some back into the rig. But I can take the moderator off to hunt when sound is not a major concern.

Sweet looking rig. Where did you get the side lever conversion, I'd like to put one on my mrod?

I really like those inexpensive Bipods I own two of them myself and they work great on bench rest

Yep, that's it.

I put wheel bearing grease in a Marauder I had once. The bolt kept getting hard to cock. Un-cockable.

Took it apart several times. No lube worked very long for me.

So I lightened the HS a little and put Disc Brake grease in it. Never had a problem after that. Sold it that way.

I'm not recommending this. Just what I did. The chart below shows the effect it had on the shot string.

Right or wrong, it made that gun shoot better for me.....

With the stock hammer, dry lubricants are recommended such as graphite. With MDS, the nylon is considered 'self lubricating'. I would just polish and wax both the hammer and tube and call it good if running a MDS Nylon hammer.

I use Dri-Slide; moly suspended in a liquid carrying agent that evaporates to leave a dry moly film that slickens hell out of steel-on-steel friction points. Lube-tune-in-a-can.

Great looking gun

No lube of any kind should be used on the hammer mechanism.of any gun. Lube is not for free. All lube creates some drag. Drag attenuates speed and that attenuation is inconsistent.

For the record...PTFE, is a solid particle also..!

Little tiny bits of Teflon. Just like little tiny bits of Moly, or graphite.

Many good lubes are made of of "solid" particles.
