its the... .30 cal rifle (?) version. it seems a bit tight but not like the one for the .22. the .22 version I need to really pull to get it though. sometimes I pull it so hard I think I am gonna snap it off in there.
the lands are .309-312....how you gonna get in the grooves?? 8mm brushes. I have a 7.62 NATO cleaning kit and it does not 'clean' 7.7 ***, 303 Brit, or any 7.62 ComBloc (except some Finns) as well as a 32 cal brush/mop because it can't reach in the grooves.
