New Ar15 owner and Sight frustration

[Hackman]

Hello. First post here. I live in Thornton Colorado. A couple months ago I bought my first ar15 a DPMS Oracle. It came with no sights. So I've been through several red dot optics and also bought a gas block front sight and a carry handle with with the rear sight. Anyway I have had a great deal of difficulty sighting it in and have now spent more money on ammo than I did on the gun just trying to sight it in. I do not know what I'm doing. I do not understand MOA or anything like that. I am losing hope and I cannot remember the last time I was so frustrated and discouraged by something. I have reached out to local shops and ranges but have not gotten anything accomplished. I would also like to get flip up sights to use in leu or in addition to my red dot but for some reason the gas block rail sits lower than the receiver rail and I'm not sure what kind of flip up sights to get. I called dpms and they were less than helpful. He said to get ones that are specified for gas block but the ones I see say things like high profile or low profile. I came here in hopes that someone in my area could possibly help me. I don't have a ton of money to spend on the sights but I jut want to know what to get. I also do not understand co witnessing. I am willing to someone for their time. Please understand when offering advice that I am unfamiliar with rifle sighting in general, co witnessing, moa, etc. I am desperate for help. Basically I just want to know what kind of backup sights would be suitable for my rifle and how I can get it sighted in and possibly make work with my red dot.

Thank you

I will attach a photograph of what I have currently. Notice the tall front sight mounted on the gas block. Would I be able to buy a rear flip up sight to put behind my red dot and have it work with my red dot and front sight?

I try to sight in off the irons first. 25 yard zero targets are easy to find online. Fire three round from a rest either bench or prone, using the irons and adjust till the irons are zeroed. Normally takes less than ten rounds.

Once the irons are zeroed, you can adjust the red dot to witness off of your irons if you have a mount that will allow that. Confirm the red dot is zeroed which shouldn't take more than five rounds.

Where do you shoot? Who do you shoot with?

Have you sought out any professional instruction?

What kind of flip up sights would I need since the gas block is lower than the receiver rail/ I am so frustrated with this. I can't afford to shoot too often. I just want a sight setup that I can use. This is ridiculous. And why is it so hard to get info such as what kind of flip up sights I would need. And how I could make them work with the red dot.

May I suggest you contact either of these two businesses:

http://www.bowerstactical.com/

OR

http://www.arktactical.com/

They are both retail establishments that also offer gunsmith services. Take your rifle to them and let them know what you would like to be able to do with the rifle and they will be able to help you.

Trying to diagnose this type of problem over the Internet will increase your level of frustration.

Just my $.02

Be safe.

For a railed gas block, you need a front sight like this: https://www.midwestindustriesinc.com...category_ID=79
You'll want the FFG version. You always need a metal front sight for a gas block. Polymer sights don't handle the heat very well.

For a flip up rear, you'll want something like this: https://www.midwestindustriesinc.com...tegory_ID=1285
Mbus polymer sights are pretty well regarded as a rear BUIS.

When not in use, both sights will be flipped down and out of your field of view.

As for working with the red dot, do you mean co-witness when you flip them up? That will happen by default once you zero both the red dot and the irons at the same distance. 25 meters (25 yards is close enough) would be a good starting distance. If you choose to stick with a fixed front sight, then it will just be in your FOV but will not affect the use of your optic. If you decide to use irons just flip up the rear and use them through your optic (assuming you stick with a non-magnified optic).

Would these flip up sights be suitable to use with my gas block?

Maybe...
So here's the thing about sights - You get what you pay for. While I am not an advocate for buying the most expensive iron sights available, I am also not a fan of cheap no names. Saving a few bucks isn't worth the frustration of sights that won't stay zeroed or can't take normal abuse.

If your current front sight is gas block height, then just get the Magpul MBUS rear and call it good. Magpul gear is high quality and very competitively priced.

Having recently tried to use a sight I got from here that turned out to be an MBUS knock off, I will second that you'll get what you pay for. My knock off sight couldn't even line up with the factory front sight properly. I personally would not buy the sight you linked to just based on the price alone.
