If you have a Samson B-TM stock for your Ruger 10/22 rifle and prefer a higher sight picture for a more comfortable cheek weld, these Samson B-TM Sights are a must-have. Compared to the 0.7″ height over bore measurement from a 10/22 rifle with factory iron sights, these elevated sights have a height over bore of 1.25″ that allow for a more comfortable and natural cheek weld.
