I have Aimpoint PROs on several rifles, and I have an Aimpoint 3x magnifier in a LaRue throw lever flip out mount. I just move it to whichever rifle I am using.
The hogs don't seem to appreciate it one bit; however, I am moving to a 1-8 on two rifles as I am wanting to push the range out more.
This is a great point and something to consider if you are comparing the price to the Kahles that was mentioned earlier in the thread.
The Kahles is great, and is actually what I had on my SBR before moving to the FAST Aimpoint + Mag combo. I have 2 rifles with Aimpoint in FAST mounts, so I can move the magnifier between them without having to re-zero anything.
The Kahles setup also doesn't weigh a lot more than the combo, but with the Aimpoint + Mag you can always remove the magnifier to save weight.
For my needs, I really prefer the Aimpoint + Magnifier combo on these particular rifles. I have another rifle with a Razor Gen 2 E 1-6 (which I actually prefer over the Kahles if you can stand the extra few ounces) and the Razor Gen 3 on order for another rifle.
I don't think you can really say one is better than the other universally, but they both have advantages and disadvantages so you just need to match it up with your needs.
About a month ago someone on reddit made a very nice chart comparing the eye relief, FOV, length, weight, etc other stats of the more common magnifiers out there:

Unsurprisingly the magnifiers with the best FOV have the worst eye relief and the ones with the best eye relief have the worst FOV. Apparently even with tons of money you still can't defy the laws of physics.
Has anybody tried the new Trijicon HD MRO with magnifier HD magnifier?

Here you go @rob_s. I know Eotech has released a 4x and 5x magnifier that don’t look very large at all. Anyone have experience with them?
Thanks for bumping this up - I’m looking at a 3x magnifier as an alternative to a LPVO on a 9” 300 BO, this is very useful.
I’ve become a bit of a SIG Electro-Optics slut due to features, exposure to them at the mothership and their warranty. I’ve been having very good luck with a pile of Romeo4Ts and I’d like to see if I can be happy with a magnifier on one. I’m looking at a SIG Juliet3 right now (not the Micro,) which I believe is in their professional quality series same as the 4T.
