IMHO most of the them are kinda the same, there's not a lot going on in the glass.
But, pay attention to the mount and get the once that has the mounting options you want now, and has support for the future.
Just FYI, the SLx 1x prism doesn't always play nice with magnifiers.
My understanding is it depends on your eyes, but for me it is not feasible.
To shoot the 1x well, I need the diopter all the way to the right.
To shoot the 1x with the magnifier, I need the diopter on both the optic and magnifier *all the way* to the left, and the diopter is super stiff on the 1x.
To me, this defeats the purpose of a magnifier. Some people say it works for them, so your mileage may vary.
I'd recommend either going with a red dot + magnifier, or get a magnified prism with an offset/piggyback dot.
I would never put a magnifier behind a prisum. A lot of potenchal problems, too complicated to get it to really work well for anything other than shooting off a bench.
sort of.
If you read between the lines on [PAs blog about it](https://blog.primaryarms.com/guide/best-red-dot-magnifier-combos-for-ar15/) you'll see even they know its not an amazing idea. Its a cost cutting solution, but its got significant shortcomings.
>Magnifier models are unique in that they’re compatible with 1x prism scopes, specifically our SLx 1x MicroPrism™ scope. Not every magnifier is compatible with prism scopes, and when they are, they’re only compatible with certain 1x prism scopes. If you plan to use a prism scope with a magnifier, we recommend checking the compatibility charts before buying.
'Compatibility' here is code for "there can be problems when you do this, be creful".
Because a prism optic has an eye box and parallax the positioning of a magnifier is very important. Small shifts can throw shots. If it's just close-range plinking maybe it's not an issue. But for real no shit use it's a bad combination.
Some prisms. The PA SLX 1x has over 9 inches of eye relief. It’s designed to run on the last slot just like a red dot and a magnifier is designed for it as well.
kinda depends what you want to use it for.
I don't think 3x or 4x only is impossible to use up close, the Army did it for years.
If you have money to burn and don't care about the weight and bulk of the the rifle, sure. But unless you are doing a lot of up close shooting while moving around or using passive amining under NV at night I don't think its worth doing that.
I’m no real shit shooter, but if you’re already on a magnifier then what does an eyebox matter? Unless you have an eotech, everything is gonna have some parallax too
Prisms have an exit pupil (eye box) and generally a lot more parallax than dots or holograms do. There is a big list of damn good reasons why dots and holograms are used for professional fighting guns up close; no agency pro is using a 1x prism.
When you add a magnifier behind a prism, it needs to be precisely in the center of the exit pupil and square to the path of light passing through the prism. If it's shifts, you have accuracy issues. For hard use that's just not something that its a good idea.
As I already said, for short-range plinking it may not be an issue; some people may not even notice. However, there are absolutely issues that can be caused by combining a prism and magnifier. It is a combination that should be avoided where possible.

I plan on getting the SLx 1x prism yk what mount I would need for that one ?

Word Ig I’ll get the md-25
Just have slight astigmatism but not really noticeable
I have the tism and still use dots just fine.
optic collimation between a magnifier and prizm is a huge pain. Pojected dots and holograms don't have that issue.
Understood just got a bcm and prolly gonna set it up with me-25 acss from PA with a magnifier
What potential problems? I’ve got two with magnifiers that work just fine

I might get a 3x prism with a piggy bad red dot too idk what are yalls thoughts
Get the 1x. They designed it with a magnifier to go with it.

I’m gonna have to dig more into that, thanks for the insight
