Robo slug, I'd go steel, the additional weight barely makes a diff to accuracy but can push on into 500 fps territory if everything else working ok.. The Delrin version just shaves in the accuracy tests...barely 2mm on group sizes..
Borne just pry it out with an O ring pick or very small terminal screw driver....then go with an 8mm O ring.
It's best to buy a little O ring selection box (small dia. Set) then you can select the ideal fit ...some of these kits very low cost on Amazon..
