Hi all, I just received the primary arms 2moa red dot with a 3x magnifier I mounted it on my AR and was fooling around with it in my basement. With just the red dot mounted the field of view is great. But when I put the magnifier on it the field of view is so much less, is this normal? This is the first time I am using any type of optic. Thanks very much

Completely normal. The magnifier will focus on a smaller angle of view and will enlarge it. At basement distances, the rds alone has zero magnification, so you can leve both eyes open. The magnifier is meant for farther distance targets.

It is normal to have a smaller FOV when you're looking through a magnified scope. This is true of any optic... the higher the magnification, the smaller the FOV. Which 3x magnifier did you get? The regular or the long eye relief one? If it's the regular, you really need to get your eye very close to the lens to get the best possible FOV, as it has a pretty short eye relief.

 

The PA red dot and 3x magnifier are very good kit for the money. Don't get me wrong, it's not Aimpoint level quality, but for the money you pay it's really good stuff. I've had the same set for a year and have shot hundreds of rounds on my AR's with it, and never had a single issue. Never lost zero either.

I have the Vortex RDS and 3x magnifier from Primary Arms. I have the mount that you can slide the magnifier out of the way. It's nice quality but I don't like the way the rifle balances with it.

I'm hating my magnifier as well, about 1.5 inch eye relief sucks!

 

 

I have the PA 2 MOA red dot and 3x long eye relief magnifier and I seem to be able to get a good field of view at about 3 inches out, which is perfect for me.

 

Honestly I am still amazed at the quality of both the magnifier and red dot for $200 combined. Only think I need to do now is replce the shitty qd mount the magnifier came with for a better quality swing mount.

Thanks for the help everyone. How far off the red dot do you guys recommend keeping the magnifier?

Here are a couple of pictures of my old upper, with my PA red dot and the magnifier mounted on it. This will give you a good visual idea of the best way to mount the magnifier behind the red dot scope:

 

Thanks for the photos, its greatly appreciated.

I have the same setup as NJDiverTony but not as much room to fit everything. It's a very tight squeeze to get the RDS, magnifier, and BUS all on the upper.

@Anselmo. Are you using a cantilever mount for the RDS? That is what allows everything to fit.

Good point there Tony, never even thought of that as an option

I have the same cantilever mount as Tony but my Vortex RDS is slightly longer than the RDS that Tony has.

 

I have a regular A2 front sight post. The mount as shown gives it a cowitness just high enough to be above the front sight. It works out nicely.

I have the same magnifer mount and I agree it throws the rifle off when u don't want to use it.

 

That's why I've been thinking about the lucid hd7 or the vortex with the screw in magnifer and using the flip one on my 15-22 or something else
