Default Scope + Red dot on AR15 Help

I originally put a Nikon Coyote Special on my Colt LE6900. I like the glass and have a 100yd zero with it. I use it for target shooting and coyote hunting and it does what it's intended to do. The area that I hunt in is also ripe for hogs. I did not feel 100% comfortable shooting a charging hog, a situation that I hope never arises, while using magnification through a scope. For that reason I mounted a Burris FastFire III red dot on top of the scope so I could have both eyes open in the event of fast moving and up close action.

I feel comfortable with the true 100yd zero on the scope but a bit torn at what distance to zero in the red dot. I'm torn between 25, 35, or 50. Being a 4" difference between the bore and the red dot, I do not want to sight it at 100 also as then I don't like the idea of having to aim high at short distance because though true, it isn't the first thought the brain would have in a pressure situation. I want to truly be more reactive with the red dot if needed.

I look forward to any tips and experience that might get passed along. Thanks!

Can you do a 45 degree mount on your rail? Slight twist for those shots within 50yds.

Sorry but I'm not sure what you mean.

I have a aimpoint comp m4 on my AR and the best overall zero that I have found is at 25 yards.

I would suggest the 45 degree offset sights. They mount to your existing rail and allow you to mount flip up sights or an RMR so all you have to do is slightly cant your rifle to make the transition.

This is what they are talking about when they mean 45 offset mount . You can get a Daniel Defense mount fairly cheap

I try to keep my rifles lean and bare. I use 2 separate QD setups, a red dot and a scope. The red dot is sighted in at 50, the scope at 100.

I agree the 45 degree mounts is superior you can pick them up around $20 at gun shows

That's very good info. I had yet to see one of those. Probably helps with accuracy seeing that it's a lot closer to the bore. With a 100 yd scope sight, what would be the advantage of a 25 yd vs 50 yd zero on the red dot?
