Hello everyone, I just picked up my first AR-15 and I need some help picking out which optic I should get. I have the Stag model 3 and on that I have the magpul MBUS flip up sights. I want a inexpensive but reliable optic (something that will hold zero). It doesn't need to be water proof but any reliability features will be cool. Im looking to spend around $150 give or take. any information will be useful! Thank you!
