Latest FX Slug Liners

Those help the harmonics ergo the accuracy. can you shoot without them accurate? for sure you can! but with them you can squeeze a bit more of accuracy, especially in larger cals (more vibration).

My slug liner shoots best with about 6 o-rings in there although the slug liners don't come with any. Any properly fitting O-ring will do. Test with a few, test with a bunch, without any and also test them in different locations. It definitely makes a difference in accuracy. Way back when, I was told all the "you tube gunners" take them out for the best accuracy. Maybe so, but not in my experience. Don't believe everything you read online. LOL Be sure and test everything yourself! Have a great day! Stoti

You can put some tape on either side of the o-ring to keep it in place.

Yes. I did just that after watching a video suggesting use of tape to keep the O-rings in place. None of my slug liners have come with O-rings, so I always use the O-rings from the pellet liner.

FX Impact MK2 PP here with 700 mm barrel in 25 cal.

I ordered some orings yesterday from my local supplier, the FX dealer don't have the oring kit in stock. I toke the online pdf and manually extracted the oring sizes for the Impact and the barrel (Canadian fixed barrel), from a total of 47 listed I ordered 30 new orings (this many in my gun according to pdf).

Anything that is making contact to a barrel and making it floating (in the gun body or inside the shroud tube) I changed the material stiffness from NBR70 to NBR90.

i wanna try that i never used them before
