I would strongly recommend a 1-4 or 1-6. They can be used just as fast as a red dot when set to 1x, and are much easier to use at distance.
I needed "the" scope for the 16" carbine .233, and figured the SS 1-6X was it. While there are other options out there, that are good, I'm sure, I was right. The SS 1-6X is "the" scope for my purposes, on that rifle.
On 1X I have a ring as a fast target acquisition, and can see the muzzle. On 6X I ran it down the range to 400 yards.
You can save a buck by staying with the 1-4X for the SBR.
