Using a microprism as a piggyback optic

[jaguar0405]

Hi! I am setting up my first AR. I have pretty bad astigmatism, so red dots starburst and are useless beyond 10 to 15 yards. I have a PA SLx 1x Microprism that performed beautifully on my first range trip. My LPVO has since arrived (thanks UPS for losing the first one), and I was wondering if anyone else has tried mounting a microprism, rather than a red dot.

What mount would you recommend, as I would need its secondary interface to be as low as possible (since the sight is already so much larger than a red dot)?

I suppose I could do a 45-degree offset, but all of what I have seen/heard from guntubers and the like is that piggyback > offset.

Prism has set eye relief unlike a RDS. Would be hard to mount two scopes needing proper eye relief.

While true, the Primary Arms 1x prism has a LONG and forgiving eye relief.

Did you figure out a solution for this OP? I’ve been searching for something too but haven't come up with anything. Best I could find was a “low pro” picatinny diving board mount but the lowest mount for the optic is 1.1”. So with a 30 mm 1.5” LPVO mount I was setting at about 3.75” overall for the SLX. Don’t mind a little heads up but that’s a bit much!

I have one of those SLX 1x prisms, nice for the price, yes long eye relief surprisingly. I am not a piggyback/12noon guy I like offset 45deg. I have thought of trying the SLX prism but never got past thinking of it. I think you could make it work if the available mounts do not put it too high/tall for you.

The HOB is not much more than a microdot, and about identical to an Aimpoint-style enclosed dot. I'm very happy with the setup and find it quite comfortable to use either optic. I have the SLX zeroed at 50y - I know that means at further ranges it will be way off, but that's what the LPVO is for.

I’ve got a red dot mounted at 9 o’clock to avoid the extra height. My left eye uses that while the right eye is behind the scope.
