I just made the decision on a Holosun HE403R. It’s going on a 10.3” backpack gun with a folding stock. The gun currently has an Aimpoint pro on it but it’s too heavy and big for my liking on a backpack gun.

I have a Romeo 5XDR which is a great, tough optic but I wanted it on another gun. I have a Sparc, but it has a slower refresh rate and you can see it comet-trailing when switching when transitioning between targets.

I was considering a T2, but couldn’t justify the cost for a backpack gun.

I went with the 403R due to:

Light weight.
No shake awake
Great battery life
Plain dot (503R for Dual reticle)
Rotary brightness dial
Protected turrets

Cheap

I got it for $140 at Palmetto. The 503R was $200. I was originally wanting the 503, but I realized I don’t love the dual reticle as much as I thought in a 20mm tube.

We’ll see how it goes.
