The B-TM Sight Package kit is ideal if you have a B-TM stock for your Ruger® 10/22® rifle (item #13007) and prefer a higher sight picture for a more comfortable cheek weld. 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 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 front sight is fully adjustable for elevation, mounting to the factory dovetail. NOTE: a dovetail barrel is required for installation - will not fit models without factory iron sights. The kit includes the following components: rear sight, front sight, sight adjustment tool, mounting hardware and 5/64" hex wrench. Fits thge 10/22® only. Made in the USA by Samson Manufacturing.
