Hello,
I am an AR newbie, only shot a “regular” AR15 a bit with the collapsible stock and whatnot. I bought a BR4 that I can pick up after the waiting period.
I am trying to figure out what optic to buy. However, the BR4 has the Remington 870 stock, so the stock is lower than on a “regular” AR.
After some reading, it seems that I want a lower height optic so I can have a decent cheek weld on the 870 stock. How do I go about finding optics that have a lower height? Is there some site out there where you can shop a bunch of brands and filter by optic height?
I’ve read about cowitnessing iron sights, and if I had to guess, I’d think an optic that is high enough to give 1/3 cowitness on
