I've got this Marlin M99 .22 that says its mircro-grooved and someone had told me that its not good to use a brass brush when cleaning the barrel. I don't believe it but just in case I thought I'd double check and ask here at shootingworld. So is it OK to use a brass brush when cleaning micro-grooved barrels? Thanks!

Yes its fine. You should really check out the Patch worm product though. It is safe for all barrels.

Kabar,

Do you still have the owners manual for your rifle? I owned one a number of years ago and the manual stated NOT to clean out the barrel ! At that time most 22 had the lubaloy coating and this may have been the reason for it. I rarely clean the barrel on my 22 mag and accuracy stays the same.If I do "clean it",I only run a dry patch thru it.

No unfortunately I don't have the owners manual. I inherited this .22 and couldn't find any manual for it. Maybe I'll take it by a gunsmith and ask. Thanks for the help.

KaBar, Hi - I have a M39 with a miro-groove barrel that I bought in 1979. The owners manual I have recommended to not clean it. I still break it down once in a while and run a few patches through it but nothing seems to really affect the accuracy.

Have you tried to get the manual off the Marlin web site?
