Unused Leupold Sako Ring Mounts Medium Matt

I have an "unused" set of Leupold Sako Ring Mounts----- 1" steel Ring -----Medium Height with a Matt Finish.  I installed them on the bases and found that the scope mounted too high for my liking.  I will ship to any address in Canada using a padded envelope with regular postage (no tracking) which amounts to approx. $5.  This is the cheapest way to get this type of item to you.  To date, I've not had any packages fail to get to their destination.  Flat rate box with tracking is another option but costs approx.$20.   Price is firm as they are brand new.  Thanks
