The best optics are the ones that are right for you and what you are planning to use it for. Do not feel pressured to get “the best optic.” Do your research, watch some YouTube videos, and choose a quality optic that you like and one that is suited for the type of shooting you will do. Personally for the AR platform, I prefer either a nice Scout style scope or good old fashioned Iron sights.

It really depends on what and how you're going to be using the firearm. Do you want a LPVO, if so the Vortex Strike Eagle 1-6x24 is hard to beat. Do you want a red dot? Try the Sig Sauer Romeo5 Gen II. Want a holographic? Try the Eotech HWS XPS2-2 1x 68 MOA Ring.

Good morning to you!! I would use a good variable powered scope like the strike eagle from vortex or a burris lpvo. Hope this helps. Have a good rest of your day.

Hi Stanley and welcome. The Primary Arms SLX or the Sig Tango MSR are both calibrated for bullet drop for 5.56/.223 and are excellent choices for the ASI 5.56; --- budsgunshop.com/search.php/q/818500018759 ---------------------------------------------------------------------- budsgunshop.com/product_info.php/products_id/137383/sig+sot61000+tango+msr+1-6x24mm ------- I have and use both and they are both great. I favor the Primary Arms just slightly better. Cheers, stay safe and enjoy!
