Optics, sights, and scopes...oh my. Noob here

[Fap]

Ok I searched just about everywhere and I get confused on the topic of "optics" for my Delton 316 AR-15.

It didn't come with a rear sight so I would like to get a rear BUIS until I get my Eotech in a few months. Now, I'm liking the Troy battle sights but it seems there's different sizes and the Magpul seems like a universal piece.

So question...which sight would be suitable for the Delton 316 Echo?

Can't go wrong with the Troys!

If you have the standard (triangle shaped) FSB, get the rail/receiver height sight. These will "lower 1/3" co-witness an Eotech w/QD base or absolute co-witness w/ an Eotech w/standard mount.

Troy's Micro and HK Style sights are gonna be too low for the AR's low rail/high cheek weld.

If you are getting an Eotech, I'd get a non folding rear like the LMT. It's basically a standard GI rear without the carry handle. You get an actual useful elevation adjustment that way.
