Let’s not forget the lockout option; it keeps your settings in place, ensuring no accidental adjustments. Oh, and did I mention it’s compatible with night vision?

Why Not to Buy: But hold on, it’s not all sunshine and roses. The sight might be durable, but it’s also expensive. The cost can make you hesitate, trust me. 

And while it’s got a wide array of features, they can be overwhelming for a beginner. The multitude of settings can take time to get used to, and you might struggle with this sight if you’re new to shooting. 

Also, for those who prefer a less techie approach to their gear, the numerous electronic features might seem like overkill.

Who Should Buy: Look, this sight is designed for shooters who are all about ruggedness and durability, hands down. If you’re the type who takes shooting seriously, this is your pick. 

Outdoor hunters and tactical professionals will find it particularly useful, especially with night vision compatibility. Seasoned marksmen will appreciate the high level of customization possible with the eight brightness settings.

  • Lightweight 

Meet the Bushnell Advanced Micro Reflex sight. It’s a lightweight, compact red dot designed for quick, up-close action. Weighing just 2.2 ounces and made of durable plastic, this sight boasts a 1 x 5 MOA dot.

That rubber button for brightness? A total game-changer. You can easily toggle through settings without second-guessing. Finally, 10 brightness settings? Yes, please!

Why Not Buy: Now, it’s not all sunshine and roses. The build isn’t quite up to pro standards compared to brands like RMR or Holosun. 

While it’s pretty good for the money, if you’re looking for that top-tier finish and build, this might fall a bit short for you.

Who Should Buy: If you’re someone who’s into close-quarter scenarios, home defense, or even tactical training, this sight has your name on it. It’s lightweight, so it won’t weigh you down during intense moments. 

Those 10 brightness settings make it adaptable for pretty much any situation. And hey, if you’re a newbie to red dot sights, this could be an excellent way to dive in without burning a hole in your pocket.

4. Swampfox Kingslayer – Compact Sight


Brand: Swampfox | Weight: 1-ounce | Material: N/A | Length: 1.8 inches | Width: 1.1 inches | Height: 1 inch

And that auto-off feature for battery conservation? That’s just the cherry on top.

Why Not to Buy: Alright, let’s talk about the drawbacks. The viewing window may be a bit small for some folks, taking time to adjust. 

That could be a deal-breaker for quick targeting in stressful situations. If you’re someone who prefers a larger viewing area, this sight might not be for you. 

Who Should Buy: The Swampfox Kingslayer is perfect for budget-conscious shooters or beginners dipping their toes into the world of red dot sights. Its light weight makes it a great addition to any pistol configuration, and those 13 illumination settings offer flexibility for different lighting conditions.

If you’re all about convenience and hate the idea of re-zeroing your sight just for a battery change, this is your pick.

My Testing

Testing the Swampfox Kingslayer was enlightening. The low weight didn’t alter my gun’s balance, and swapping batteries was hassle-free. 

The auto-off feature? Genius. Saves me worrying about battery life. While the viewing window took some getting used to, the clear glass and multiple brightness settings provided excellent 

visibility in various lighting conditions.


  • Affordable
  • Side-mounted battery tray
  • 13 illumination settings
  • Lightweight
  • Auto-off feature


  • Small viewing window

5. Predator V2 – Best For beginners


Brand: Tacticon | Weight: 5.15 ounces | Material: Aluminum Alloy | Length: 3.50 inches | Width: 1.25 inches | Height: 2.25 inches

Why It’s My #5 Pick?

  • It comes with a 45 Degree Mount.
  • Affordable option. 

The Predator V2 Reflex Sight by Tacticon is a budget-friendly choice with nifty features. Aim with lightning speed thanks to the crisp optics. 

It’s versatile and compatible with rifles, shotguns, and pistols. Made from aluminum alloy, it’s pretty solid. It weighs 5.15 ounces. A 45-degree offset mount is included, ready for offset sighting. 

Plus, you get 9 brightness settings and 4 reticle options in both red and green.

Why to Buy: Affordability is key here, but you’re not sacrificing much. With 9 brightness options and 4 reticle styles, this sight adjusts to any situation. 

The auto shut-off is a nice touch, conserving battery when not in use. It even comes with a 45-degree mount, adding to its value.

Even though it’s not Trijicon-level, for a newbie or someone wanting an extra sight, it’s spot-on.

Why Not to Buy: Now, let’s get real. The battery life isn’t the greatest because it uses Alkaline batteries, which are less durable than lithium ones. 

So, if you’re going to be in the field for an extended period, that could be a snag. It’s affordable but not built to last forever. The aluminum alloy is decent, but it’s not military-grade.

If you’re looking for a rugged, long-term option, you might want to keep searching.

Who Should Buy: This sight is an excellent choice for beginners or those on a tight budget. If you’re new to the red dot game, this gives you a taste without breaking the bank. 

It’s also ideal for those who want an additional offset sight for their setup. Given its 45-degree mount and various reticle options, it offers a lot of bang for not a lot of bucks. 

However, it might not meet the durability expectations of a pro shooter or an outdoor enthusiast who’s always out and about.

My Testing

Even though I own pricier models like the Trijicon RMR TYPE 2, using the Predator V2 was interesting. 

The auto shut-off was useful, and switching between reticle styles was fun. However, the battery life was a letdown. Still, for a budget sight, it did more than just the basics.


  • Affordable
  • 9 brightness settings
  • 4 reticle options
  • 45-degree mount included


  • Short battery life
  • Not as durable as high-end options

Know Your 45 Degree Mount Red Dot 

The following information will enlighten you about a 45-degree mount or offset red dots and why you need one. 

Offset Red Dot Sight       

The Offset Red Dot Sight is a mini dot that you mount along with your primary rifle optic. Initially, it was a popular practice in competition, and then due to the many benefits it offers, they are used for service as well. 

The two types of offset red dot sights are angled and piggyback. 

The angled offset red dot is the one you place beside the optic at an angle of 35 or 45 degrees. And the Piggyback is the one you put on the top of the optic. Here we are concerned about the 45-degree mount red dot. 

Why do you need an Offset Red Dot Sight?

An offset red dot sight gives you fast target acquisition when engaging targets at various distances. It’s faster than any other optic. Moreover,  it is always good to have a backup if your primary optic breaks or fails. So, an offset red dot paired with a good quality mount does not harm.

What does a 45-degree mount sight offer?

An angled mount sight gives an excellent cheek weld for accuracy and recoil management. It also has a standard height over bore, making it easy to predict holdovers when you shoot inside your zero distance. Also, it gives more clearance around magnified optic scope turrets. 


Alright, folks, let’s wrap this up. After rigorous testing, combing through features, and real-world use, I’ve got to say, Trijicon RMR Type 2 is my top pick. 

Now, each of these options brings something to the table, whether you’re a seasoned shooter or just getting started. Budget considerations, compatibility, durability—oh yeah, we’ve gone through it all. 

But at the end of the day, my choice emerges from a blend of real-world practicality, seamless operation, and that indefinable ‘click’ between shooter and tool. Whether you’re a weekend hunter or preparing for more tactical settings, the key is to know your needs. 

Be clear on your primary use case, your firearm, and your skill level before you dive in. 

Remember, a sight is a tool that should enhance your natural abilities, not replace them. So go ahead, pick your winner, and see your skills soar. 


What is the best-angled offset mount?

The best-angled offset mount is the one that angles the sight at 35 or 45 degrees relative to the bore axis.

What is the best red dot for a 45 Degree Mount?

The best red dot for a 45-degree mount, based on my extensive testing, is Trijicon RMR.

What is the difference between 35 and 45 offset red dot mounts?

The 35-degree offset allows for a quicker transition between red dot and magnified optic, while the 45-degree offset requires more movement and weapon manipulation.
