Could someone please explain why the bolt and boltguide haven't to be lubed?
I read the Manual about 313 times and didn't find a point which says that the bolt has to be lubed...
Thanks

I'm not qualified to explain how it runs without grease, but can say that grease on the bolt guide and bumper can cause bolt stick. As such, you don't want to use grease on these areas.

Thanks a lot. What about the outside of the bolt? Same?

Best bet is that if the manual doesn't mention it, don't do it.

There is no need to lube the bolt. A tiny teeny weeny amount around the rubber bolt tip wouldn't hurt, but the rest can be left dry.

The only point on the bolt that does need lube is in the little hole in the centre of the bolt insert stem right in the back of the bolt. This slides over a part of the poppet that has an o-ring on it so it does need, again, a very small amount of grease.

The main thing is that the bolt guide and particularly the bumper and the back face of the bolt are kept nice and dry so that the bumper doesn't stick to the back of the bolt.

Thank you very much!
Seemed a bit strange to me because Ego and Geo bolt have to be lubed but now I know better ;D Thanks.
