Mine is intended for CO elk, so I installed Mark 4 Picatinny bases under a Lyman 57 sight, which has a repeatable quick release mount. I can switch between fixed sights, either with peep or as ghost ring, a scope, or I can mount an Aimpoint Micro. All being repeatable so to add versatility to the rifle.
I can leave the rear sight in place and install an Aimpoint Micro on the front Mark 4 Picatinny base so that the fixed sights co-witness with the Aimpoint. Lots of options.
The sight maintains a relatively low profile, and though I can remove the peep and use it as a raw ghost ring, with the appropriate sized peep, accuracy is exceptional within the range I'd use the fixed sights. Using the fixed sights as a ghost ring, during low light times within about 50 yards or so, I'm nearly as fast as with using an Aimpoint Micro, which by the way can mount on the front Mark 4 Picatinny base.
The factory Rem sight has a .0750" wide bead, which is a bit too coarse for me beyond about 150 yards. I replaced this with a 1/16" bead which allows me to go out to about 200 yards before it subtends too much.
100 yards with scope, the rifle shoots insane tight groups when I use optical sights.
150 yards using the aperture sights, I can hold under MOA with my eyes and the bead is fine enough to be workable out to about 200 yards under field conditions.
Not sure of your regs vs CO, but I'm leaning toward the new Federal sabotless muzzleloader bullet in lieu of the Parkers for elk. Otherwise, the Parker bullets for everything of size or distance where legal. The factory Rem bullet and sabot combination is not quite as accurate, but still holds MOA and is plenty capable to handle most normal medium sized game applications where a jacketed bullet / sabot is legal.
