John from United States, PA Public Profile

I had this sight back ordered for 2-3 years before it was available, so I was quite excited to finally have it arrive in the mail. To mount this sight the tang on the Lyman's Great Plains Rifle only one hole must be drilled and tapped first. But I ran into a problem that prevented the peep sight from being mounted. The peep sight and it's base/shim are flat, but the tang is curved. I had an experienced gunsmith mount the sight for me. He had to mill a flat section on the tang (and re-blue it) before he could drill and tap it. Once mounted, the sight was easy to adjust. I liked the quick detach feature, where the sight can be removed with the push of a button. This button can be locked in place with the tightening of a set screw. Overall I like the designed function and the adjustability of the sight. I could easily adjust the sight with an inexpensive ($4.00) set of "precision screwdrivers" available at all hardware stores. I have adjusted the peep sight to lined up with the existing barrel mounted front and back sights. And I am excited to head to the rifle range to fine tune the sight. The directions on its mounting and use are include and reasonably well written. While mounting the sight is a challenge for the average do-it-your-selfer, I give the use/function of the sight 5 out of 5 stars.
