Merit aperture products
Peep sights are da bomb.I love classic, steel Lyman and Redfield receiver sights. I have them on Winchester71,94,94BB,Savage 99's.Tang sights on Browning53 and 65, Bolt peep on Win 71, and Sako peep as back ups on my old Sako bolt actions.
I use the Merit#4 Hunting Disc on many of these sights. It's an adjustable disc aperture so small hole for target shooting, twist to large ghost peep for hunting and everything in between.
I am sure I read a warning somewhere (Elmer Keith I think) against using tang sights on heavy kicking rifle as the recoil might lead to the sight poking your eye out.Not sure if this is true but I only have tang sights on a 32-20 and a 218Bee.
And of course, don't forget the beautiful peep sight on the M1 Garand.
