First, I agree with most of the prior post except for the need for the hood on the front sight. He likes it without, and he probably has good reasons. I like it with the hood for these reasons.
1. Keep the hood on but get a front sight installed that is high enough to have the dot very close to being in the middle of the circle the hood makes.
2. Adjust the peep sight so you hit dead on at 100 yards. (We are talking heavy woods here. I hunt in heavy woods and brush in northern Minnesota where 100 yards is a long shot. You will only be about an inch high at 50 yards.)
3. Unscrew the peep insert from the sight and store in a safe place.
4. Now is the interesting part.
When you look through the sights you will see a circle within a circle with the dot of the front sight in the middle of the smaller circle. Your brain really wants to place the smaller circle in the exact center of the larger circle, and will do so without your really thinking about it, which in turn makes this a really accurate sight.
Secondly, this is really a fast sight because when you have one of those brown bombs ripping through the brush about ten or fifteen yards from you, all you need is brown hair inside the front hood in the general area of the kill zone and you have meat on the table.
I have this setup on a Ruger .44 Mag Carbine. It's my go to gun for drives in heavy woods and brush. I have taken a number of deer with it and have never lost one. That slow moving lead pumpkin has killing power way beyond its statistics.
Try very hard to shoot with both eyes open- it makes it even faster.
Good hunting,
