I personally LOVE Peep Sights, But they can be a BIG disadvantage in low light hunting situations. Nearly Every Rifle i own has Peep sights on them with 17 Series Globe front sights that i can interchange the inserts in, I use very fine Lee Shaver’s BPCR inserts in my Front sight Globes. I mostly shoot Bench/Targets. In low light hunting situations you will be hard pressed to beat Fiber optic open sights, you could always use a Tang Mounted peep with a bright Fiber optic bead front sight. Skinner makes a very simple yet very nice Peep sight called “The Renegade” That mounts in the existing rear sight holes of your renegade

I have 2 sets of Williams Fiber optic open sights that came with my Green Mountain LRH Barrels, they would also work well for hunting.
