Adding a Red Dot to a Beretta CX4 Storm

If you mount a red dot directly on the rail you can co-witness the iron sites.

Almost every site made will bolt straight to a rail. You would not want a spacer on the storm.

Straight on the top rail. Many Aimpoints come with a raised QD mount anyway, and it's a good thing. I think I understand why you brought this up. The CX4 is really for dynamic engagements, offhand rather than bench rested. So a little elevation will do good, a tight cheek weld is not necessary. It also helps to keep your nose away as much as possible from the blowback ejection port.

Aimpoint with standard Aimpoint mount that comes with the COMP models (I think its the low mount) co-witnesses just fine.

I think co-witnessing is overrated. Aimpoints hold zero very well, their batteries last for a long time. In a sporting carbine, co-witnessing is irrelevant.

You want to co-witness it both so irons are still usable, and so you can still get proper cheek weld when shooting with the red dot. Go with an Aimpoint in a low ring. The EOTECH is designed for an AR height sight line, and will sit too tall on the Beretta, which has more of a HK sight height.

An Aimpoint works perfectly on the Storm as does the Lucid HD7.

I do not recommend co-witnessing as that actually slows you down rather than badly lining up three items in different focal planes.

A red dot alone is lightning fast and is hard to beat as a defensive optic.

I run a Primary Arms dot on mine; it co-witnesses.

If you don't have a co-witnessing sight, you probably don't have a cheek weld. And if you don't have a cheek weld, you won't be consistent.

The iron sights on the CX4 fold down, so once you zero your dot on the irons, you can fold them down and out of view. Then if you remove the sight, you can put it back on and check your zero vs. the irons, without having to burn ammo just to re-zero your sight.

Another dot option would be a Burris Speed Dot 1X35, 3 MOA Scope (co-witness)

If you're focusing on the iron sights at all when shooting with a co-witnessed red dot, you're doing it wrong. I don't even notice the irons. Shoot with both eyes open, and look through the dot at the target. You should not be any slower with a co-witnessed setup. Being able to get cheek weld will make you more precise though. That is just part of the fundamentals of marksmanship. It is something you can sort of get away with when the targets are large and close, but it is still poor fundamentals... and why cut corners if you don't have to? More points of contact with the rifle is always a good thing. If you can fold the irons down on the Beretta, it's just that much easier to run a co-witnessed setup. Almost like it was designed for it. Funny how that works.

My CX4 had a 2-position flip rear sight, not a foldaway. The front sight was a winged post.

Hmmm, mine is a 3-position rear sight: short range peep, long range peep, and folded down for no sight. The front post also folds down, out of view.

I also have the Burris Speed Dot, and I love the set-up!

You got a "flip up sight package".
