you want a low viscosity wet tube or a dry lube,since anything at all thick will slow the striker,and worse yet,the effect will vary with temperature.Breakfree will work,I like Finishline chain lube,in very small amounts,since it will build up.Either is applied after smoothing and burnishing in dry moly.
The very best I've found is a coating of "Gearkote" a baked on moly resin.
The cocking arrangement of the QB puts quite a bit of "tip" on the striker,so surface pressures are a lot higher than you might think.Very smooth surfaces in the tube and on the striker help,but don't remove much metal or the "tip" gets worse.
