I have the GLX in 4-16 and 6-24. I can't comment on the last 5 minutes of light. I bought the 4-16 last year and used in only once hunting. It was on an Oryx mid morning. The scope is rock solid and the glass is good. I don't know how it compares to high end glass.

It was easy, everything tracted fine. I really like the their GLX line. It has a lot of nice features for the money. Glass is good to my eyes. It's some of the better glass I own. The weight is really nice for the size and features of the scope. The GLX line is made in the Philippines.

I think you will be pleased for the money. Their reticles are really nice. I have the ACSS HUD on my 308 which I used for hunting. The 6-24 is a pure MIL based reticle called the Athena. That one is on a 223 bolt action.

Without Primary Arms optics experience, I would spend $750 on a Burris XTR II.

The Burris definitely has more travel. The PA is 30mm and only 23 ounces so it's much lighter.

I picked up that Burris XTR II 3-15 for $599. Total bargain. It's a tank.

Thanks, not for me. I'm good on scopes for a while, I hope. But I'm often asked if I've heard about, or know anything about, etc........If someone is looking for an optic in this price range I can tell them what I've heard from someone with some field experience.
