My 59 year old eyes are not as proficient as they used to be, does anyone relate? I am "looking," no pun intended, for an extremely compact optical sight that will install directly into the rear sight of my Ruger Bisley that John Linebaugh converted into his .475 Linebaugh. Presently, the rear sight that I have on the gun is produced by Bowen and is excellent in all regards, but still it is not sufficient for the 50 yard shots on large game up to and including Cape Buff. I am searching for a zero magnified optic that will replace the Bowen rear-sight. I hope that an optic exists whereby I will not have to tap additional anchor points into the barrel.
Thanks for your help. JHT
