I'm looking for 3 scope recommendations

In my opinion. You can’t go wrong with Vortex Viper or Leupold VX 3 and above

By long range I mean 300 yards. That's what I was trained for open sights so I figured if it's good enough for open sights I can get a bit more "up to par" with some good glass. All of my Ars are built by me using various parts so there is no "price per say". They vary.

I've looked hard into Vortex and medium into Nikon.

Shorter range Leupold VXR Patrol 1.5-4
Longer Range Leupold VX3i
Red Dot Aim point

If you want to spend a little more coin the Vortex razor GenII 1-6 has amazing glass. I have one on my SBR 11" and the FOV is badass.

“Long range” - vortex pst gen ii 5-25

“Midrange” - vortex pst gen ii 2-10 in whatever reticle matches the 5-25 you get.

*i’d look for scopes that have the same reticle just to make things simple. Take a look also at the Nikon black series (no 2-x so that would be a deal breaker for me for mid range) as well as the Burris xtr ii series (5-25 and 2-10 are available power ranges)

Red dot - eo tech and aimpoint is usually my go to. EXPS 2-0 if weight isn’t and issue, aimpoimt micro if it is.

You can connect at 300 yards with a 2-7x or 3-9x. And I guess your “mid range” would be like a 1-4X. Agreed with others that Nikon, Vortex, and Leupold have good offerings. If you’re willing to spend a bit more, Meopta makes some very good scopes.

For red dots, get an Aimpoint Micro or a Trijicon MRO. The micro-style dots weigh very little and have a great field of view. They also have a ton of battery life. I’ve maybe turned my Aimpoint off like 5 times in the past 4 years.

For your long range, I’d highly recommend Leupold vx5 HD 3-15x44.
It’s an awesome scope and not very heavy.

Good suggestions so far but I’d look at the gold dots from Holoson. I don’t know if they have more than the one I got (they just came out) but I really like the gold...easy to see in the day light. I haven’t shot it yet tho.
