I put a Williams peep and a front fiber optic "firesight" on my 10/22 a couple of years ago...


I believe it is the WGRS ramp peep... Check www.williamsgunsights.com.

It installs on the rear tapped holes

It is in there...The you'll probably have to install a higher front bead, because the factory bead is too low for the peep...I installed mine myself ( and I'm no gunsmith) with no problems..
