I bought a Primary Arms GLX 4-16x 50 last year and it has been great for my purposes. Precise tracking, glass that performs well above its price, and the reticle design is what I was looking for. While hunting the battery cover for the illuminated reticle unscrewed and fell off (didn’t check its tightness and was walking with a sling) and I emailed them and they replaced it free of charge and it arrived at my house 3 days after the email. Wanted to share my experience with PA in case anyone is curious
