Trying to decide between these to for a SBR 300 blackout. How do these compare?

I almost bought the Primary arms but it was always out of stock when I was trying to buy one. I bought the Strike Eagle for my AR 10 and am very pleased with it.

I've had both and gotta say you can't go wrong with either. I did prefer the PA reticle tho.

I might be looking to sell my Vortex strike eagle if anyone is looking

From what I have heard it's the same exact scope minus the reticle. I have looked through both at one point or another and they are excellent value.

I think I slightly prefer the reticle of the Vortex though because I like a finer point of aim to instead of the slightly larger dot of the PA 1-6x. Can't go wrong either way though! Both great companies with great customer service.

I would look at the SWFA SS as well. It's a 1-4 but it has a very well thought out reticle and low profile turrets.
