Query: Nice Bore guide, quick & easy

I got this for use in multiple calibers, on my better guns that are new or near new.I think keeping the rod straight in the chamber, so it doesn't rest on the throat area whendriving a brush or tight patch to the crown, is a good thing. It worked well on a .300 Win MagTikka, a .243 Win Howa and soon will try on a new Marlin .45-70 I got. Not sure it will fit that one.Seems like it will hold-up well and easy to fit to the chamber and back of action with thecollar accessory included. You can add solvent or cleaner into the window and onto the patch or brushwithout problem from a squirt bottle. I'll keep with it.Great,William
