AR556 Red Dot Recommendations

Own many firearms, but this is first AR15. Would like some recommendations for a nice red dot site for the Ruger AR556. Will mainly be at the range or plinking, no more than 200-250 yards. Hate the iron sites, but ok for backup. I've been reading a lot about red dots, but not sure I know that much about these sites or what would be best for me. Like to spend no more than $150. Want a riser so can absolute co-witness with the M4 A2 front triangle site. Don't want to take this front site off. I'm think a 2 to 4 MOA, red and green dots, some brightness control, parallax free, no magnification now maybe in future, maybe a micro dot as apposed to full size. Some models I've researched include Atibal MCRD-II, Bushnell TRS-25, Primary Arms Micro Dot, Vortex Strikefire II. So, there you have it. Would appreciate any advise or recommendations. Thanks a lot.

Primary arms microdot is good, but out of what you listed the vortex strikefire wins hands down. Lifetime warranty no questions asked, and includes mount, thats what I would recommend, bright red version. I own several of them some on ar's, and one on a hk91 in 308. No problems and nothing but praise for them.

I have a Vortex Strikefire II. The unit is solidly constructed and it came with very stable mount allows me to co-witness the iron sights. Had it on my AR 556 for over a year and pleased with its performance. Biggest complaint is the cost of replacement batteries.

I only use the rifle for short range (<100 yds) quick target acquisition. The unit is accurate.

Excellent product for approx. $160.00.

Here's another vote for the Vortex. Very nicely constructed, easy to see through and doesn't cost $$$$$$$$. I'm saving up for a VMX-3T magnifier for mine.

My second choice would be the Bushnell. Cheap, nicely built, but a bit on the small size for my old eyes.

And the Winner is...

Winner: Vortex Strikefire II. This is a fine red dot optic for a budget price from everything I read and hear.
A few more considerations. There is a red dot only and a red/green dot. I like the idea of changing colors for variation and some eye relief for these old eyes. However, I read that the red dot only sight is much brighter than the red/green. Is there that much difference? What are the brightness range settings for these two sights?
Also, I want to be able to absolute co-witness with the front M4 A2 triangle style sight, putting the dot right on top of the front sight post, with the rear iron folded down. Will I need to purchase a separate mount 1 3/4 inches from rail to middle of the lenses? The sight comes with a lower 1/3 co-witness mount, 40mm from rail to center of lenses.

Have the StrikeFire II ahead of the VMX-3T and love them both on one of my AR's. Have a Bushnell TR-25 on a Ruger Charger and have a blast with it also.

When I bought my M4A2 a friend recommended the EOtech red dot. Expensive but nice. I found that on using my rifle for varmits, feral hogs, and with "old eyes" I needed a little magnification. After a bit of research, I traded for a Burris AR332, with 3x magnification, rings around the red dot, illuminated red and green reticle, or not illuminated. I've use the lighted reticle early morning and latte afternoon, but the black has served me well. The rings around the dot more quickly helped with moving hogs for followup shots. It's still on my AR. It's not the cheapest option but worth it for me. Recoil hasn't affected it.

I would recommend the bright red. I own both, and the option is nice to have both, however on bright days the red green washs out. The bright red is better in bright daylight. The red green works better inside, or in darker area's but can be used outside just be aware Its not as bright as the bright red.

It can be ordered with an absolute or lower 1/3 cowitness. The absolute is what you seek. I would recommend the cantilever absolute mount, it gives you more room on the top of the reciever by moving it foward.

Here is one I built with the absolute cantilever mount, and strikefire2

I love the eotech, own many probably 4 or 5. They are pricey. The aimpoint comp 3 is a great own a few of them. The strikefire 1 is good, the 2 is better with the rear on and off switch, as opposed to the side switch on the 1. I have a burris fastfire 2 piggy backed on a 3x9x50 nikon bdc, also a great combination. My other favorite is the primary arms micro dot, have one on a mark 3 target, uzi, 10/22, and mac 11.

I must also vote for Vortex. Went to a 2 day carbine class, 20 degrees one day, and rain on the second day. I actually had to point my rifle up to pour the water out of the sight several times. Part of our challenge test was ringing steel at 300 yards (furthest I had ever fired, red dot sighted for 25 yards), I had to aim a little high, but the red dot stayed accurate through all of this, and hearing that ding come back after a couple of seconds was quite satisfying!

Here is the setup on my Ruger. It is a Sparc II with a VMX-3T 3 times magnifier. The VMX is a flip mount and can easily be flipped out of the way. With the magnifier flipped out of the way I can flip up my rear sight if needed.

OK, another option, without being too big a pain. How about the Sparc II vs Strikefire II? Roughly the same price. Really like the 2MOA vs 4MOA. Sparc is smaller and lighter. Will the 22mm be a bother vs the 30mm lenses in the Strikefire? Can absolute co-witness or add magnifiers to either sight. Thoughts or Recommendations for the AR-556?

I like the smaller dot as well as the compact size. You might check out their new Sparc AR also.
Here's my Sparc II
