If you have a Samson B-TM stock for your RugerA(R) 10/22A(R) 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 10/22A(R) rifle with factory iron sights, our elevated sights have a height over bore of 1.25" that allow for a more comfortable and natural cheek weld. Mounting to the factory tapped holes in the receiver, the rear aperture sight is fully adjustable for windage and features protective shoulders. It is machined with a Picatinny rail section that also allows shooters to mount an optic that will co-witness with the iron sights. The winged f Mfg: Samson Manufacturing Corp
