The mounting hardware you’ll get out of the box with your HM3X magnifier is an integrated quick-disconnect (QD) spring-loaded swing mount with included spacers for absolute co-witness or lower third co-witness. 3x24mm optical configuration with lens protecting coatings – Comes with a QD spring-loaded swing mount and spacers – Constructed of MAO finished aluminum nitrogen purged with an IP67 waterproof rating7.
Bushnell Optics TransitionEstimated Price: $150My Review: Bushnell is a high-quality mid-tier brand in most cases and when you can’t or don’t want to pony up for the big-ticket brands, Bushnell is always a solid contender in the middle offering a great amount of value. What you get in terms of magnification here is a 3x25mm optical configuration with the Bushnell set of proprietary lens coatings.
What really stands out to me is the 3. 5” eye relief, which is absolutely insane and is one of the most comfortable magnifiers to use on this list! It’s built to be used with the Bushnell TRS-25 red dot, which is an excellent red dot I might add, but you can also pair this puppy up with tons of other highly popular red dots like the Vortex Strikefire 2, EOTech, SightMark, etc. It is a little cheap and you can tell it doesn’t have the optical clarity that you would find from Aimpoint or EOTech but it is still waterproof and quite durable since it’s constructed out of aluminum.
It’s by no means as durable as the Sig Sauer or Aimpoint magnifiers but still, it’ll survive a little abuse and keep trucking along! 3x25mm optical configuration fully multi-coated with fast-focus eyepiece adjuster – Comes with a basic swing style mount – Constructed of aluminum and is nitrogen purged for waterproofing8.
Sightmark Tactical XT ProEstimated Price: $135Magnification Level: 3X, 5X, 7XMy Review: First things first, with Sightmark we always get options! These are available with your choice of 3x, 5x or 7x magnification versions. Unfortunately, they don’t have a variable power model so you’ll have to choose one of those, which I’d probably recommend the 3x or 5x versions.
7x is a little high for use with most red dots unless the red dot reticle you’re using in co-witness is especially small and thin. Of course, these are made to be used with Sightmark red dot sights, which are excellent budget grade red dots, however, they are compatible with tons of other sights such as red dots from EOTech and Aimpoint!
A serious note here, these are not waterproof but are actually just IPX6, meaning they’ll survive some rain and maybe even a splash of water but they will meet certain death upon submersion. I usually recommend getting fully waterproof optics, however, with the value this sight provides and how good it is at this price point, I think it’s something you can ignore so long as you’re careful and don’t submerge it!
3x, 5x, or 7x magnification with a 28mm objective lens with AR green lens coating for light transmission – Comes with a quick-release slide to side mount which is fairly similar to the other regular swing mounts – Constructed of anodized aluminum and encompass an IPX6 weatherproof rating9.
Primary Arms LER Gen IVMagnification Level: 3XMy Review: Before we get started, it’s important to note that the price is $100 for the magnifier but Primary Arms didn’t originally include the mount with the magnifier but instead sold it separately. This is good because most people end up buying aftermarket mounts anyways but it’s just kind of odd that they’re one of the few brands to not offer a mount with the magnifier.
I guess you can think of it as saving money, though, and instead, being able to choose the mount you want. Primary Arms makes a lot of things that, leaving out appearance and extra functionality, are quite good for the price and can last a long time.
