Hi all! New member here looking for some help. Ive recently decided to get a magnifier for my 16" AR15 to complement my Romeo5. After doing some research, I've narrowed it down between two, the Sig Juliet 3 and the Sig Juliet 4. Looking for some help on whats different between to two. I know the juliet 3 is 3x (3.25x) magnification whereas the Juliet 4 is 4x (3.75x.) Besides the magnification, is there any other differencences between the two? Is the extra magnification worth the extra money? Thanks in advance!

I run a holosun HM3X with my Romeo5 and they work great together.  About 1/2 the price of the Juliet3.

The Juliet4 is assembled in the USA, which does explain some of the price difference.

I have one. The place where I think the Juliet4 really shines is when paired with a reflex sight with a BDC reticle (like the Romeo6T or 8T). The magnification difference between 3x and 4x is not practically very big, but it's enough to make the BDC reticles much more usable.

Eye relief and eyebox will be slightly more restrictive with the Juliet 4, but I felt it was worth it.
