    I just picked up a bottle of this low viscosity Huma oil designed for regulators. It should do the trick. https://utahairguns.com/huma-air-airgun-lube-silicone-grease-10ml-gram/

    Yes, in my case it did get progressively worse over time. You can get the tool here: https://www.capefearairguns.com/collections/airgun-tools/products/fx-impact-hammer-seat-removal-tool-v2

    FX Hybrid .30 cal and STX Superior 1:40 700mm liner

    Your right, it is super accurate with pellets. I tried 1 box of the Zans and lover them! I get a lot of cross winds here and was holding 3 mils at a 100 yd with the 44gr pellets but the Zans were only 1/2 mil. I tuned the Zans to shoot at 875 and super accurate. For the fun of it, I was...

    Thanks, I will give the javelins a try. The Hybrids also shot poorly for me.

    FX Hybrid .30 cal and STX Superior 1:40 700mm liner

    I have a fairly new M3 .30 700mm that came with a STX Superior 1:40 liner. Has anyone tested Hybrids in this liner compared to the 1:22?

    30cal javelin slugs FX barrels

    Good info, thanks for the posting. I have a .30 700mm, and getting kind of bored shooting pellets, decided the to try the Javelin 52 and hybrids. The Javelins shot a 3 or 4 inch group at 100yds running about 940 (standard barrel). The hybrids about 1.5 at 967fps. Thinking about trying out a...

    Just tested again after letting it sit over night and all good with 919, 916 and 919fps. 😁

    It's working great!! Changed the O-Ring, cleaned and re-lubed everything and it has been shooting like new. Been doing random test shots since yesterday and no more issues. Just need to tweak the tune a little. Shot count: 18 Low: 914 Hi: 923 Avg: 919 Spread: 9 STD Dev: 2.5 921 923 914...

    FX FX Impact M3, clean and polish internals?

    My M3 after 6 months of usage.

    I took it apart to change the O-Ring and was amazed at how much grime built up on the valve stem rod. The O-Ring looks like it had better days for sure. I ordered some 3M polishing cloth and will give everything a good cleaning and polish.

    I might reach out to him for the part. Looks very promising. Mine has been up to 100fps slow after sitting a day and takes 8 shots or so to get up to tuned speed. I ordered the Hammer Seat Removal Tool and some O-Rings. Going to replace the o-ring tomorrow.

    The issue returned after I re-adjusted my valve adjuster back out to about line 5.5 (factory default) from just above 4. Worked fine on line 4, could be a coincidence but kind a starting to look like an issue related to the valve adjuster spring tension. Going back to line 4 for some more...

    FX Fx impact M3 30cal

    I would stick with the JSB or FX 44.6 pellets for now. That is what the gun is tuned for from the factory and you will get allot more shots. To shoot slugs you will need to crank up the power and make adjustments to the regulators and power wheel. I wouldn't recommend making any changes until...

    The JSB and FX 44.6 pellets have been the most accurate for me.
