Guys I have an Austin & Halleck Mountain Rifle .50 cal that I want to start shooting but with my old eyes I can't see the buckhorn sight / silver blade combo very well so until I can come up with a good open sight combo for this gun i've just been saving it. I need a recommendation for sights and was wondering if you "Hawken" guys remove and clean the breachplugs on these guns like you do an inline? Thanks for the info!
