Is it recommended to polish the hammer and bolt on a rapid.

Daztilley

Polish the hammer with autosol- no need to polish the bolt - but run them both dry - no grease 👍

As  specified by Theoben the best stuff for the bolt is Molybdenum sulphide grease.
Its not cheap £40+ for 100g ...£60 for an aerosol but you can pick up small amounts  for example
Tinbums 'Bum-slide 'orrible black gunk that gets everywhere if you're not careful.

Good news is you only need about 1/4 a match-head polished into the whole bolt ...just so that it has a dry sheen.
Transforms the action...miles better than 'dry'

A light hand polish works good for me...
Not a heavy Polishing ..You don't want to change the dimensions!!!!
Hammer. Polish. helps consistency...
Bolt Polish, Well it help make cocking and loading almost effortless.
Also I was a Never a fan of Theoben's slopping on the Molybdenum Grease !!
I use Krytox. Expensive Teflon base synthetic grease...

Ahh...Carboflo? Fluorofluid.... aerospace grade lube.
it is expensive ...BMW rip their customers £35 for3g  or 5g to stop annoying  plastic sqeaks.

bearing in mind the small areas of contact wear on bolt blueing which is mostly dust and crud areas ;theres no point in polishing them bare.

Well the new MKII the bolts were blue and the finish wasn't too bad...just a light rub down
with a non-embedding grit polish did wonders..

But the early ones, they were Parkerized.. so the finish was rough...
So Polishing just the contatct looked wierd....
So I polish the whole bolt body....
Everyone has their way...

knowledge I can only bow to and digest

My 96 R7 and 01 bolts are wearing thin but are smooth glossy black
The new RAW bolt I fitted is a different story ...poor in comparison. Not rough...just not the same quality of prep? Maybe in 20 years  ;)

I didn't polish any part of the bolts; most of the finish-some barely microns deep-has survived 20 years+ of use. I ran a thumbnail around the probe end and there weren't any scratches.
Wouldn't polish it all...would be like a hamon.
