Holosun 515GM - Best Overall
The Holosun 515GM offers a budget-friendly alternative for those seeking a good PSA AR15 red dot sight comparable to the Aimpoint Micro for just under $500, considering it the best for tight budget buyers.
It has the same mil-spec grade construction as the renowned Aimpoint Micro, and any Aimpoint micro mounts work with this optic for users who need different optic heights.
Additionally, the HS515GM is equipped with a 65 MOA ring and a center dot, which facilitates quicker close-quarters combat target acquisition compared to a standalone 2 MOA dot. Users can also switch to a 2 MOA dot for reduced reticle obstruction by holding the "-" button for 3 seconds, and revert back in the same manner.

Holosun 510C - Best For Range
One of the most significant advantages of the Holosun 510C is its large lens window. This feature facilitates faster shooting by allowing for easy aiming with both eyes open, which is crucial when moving or transitioning between targets.
From my experience, the Holosun 510C stands out especially considering its price point of under $300. It's not just the affordability that impresses me for a $700 PSA AR15; the 510C offers a large field of view, essential for fast target acquisition in both practice and competition settings.
The large CQB 65 MOA reticle circle is perfect for range estimation and quick close-range holdovers, making it an invaluable tool in various shooting scenarios.
The integrated solar panel serves as a backup, kicking in if the battery dies while in the field.
At this price point, this is one of the hottest selling red dot sights that most new shooters are buying.

Aimpoint Pro - Best Value Aimpoint
I recently decided to purchase the Aimpoint Pro for my PSA AR15, and I must say, it's been an excellent red dot sight for AR15. Priced at under $480, this classic 30mm tube style red dot sight not only fits my budget but also includes a mount, which makes it an incredible value.
While there are newer models like the Aimpoint Comp5 available, I found that the Aimpoint Pro offers outstanding performance at a very reasonable price. For anyone in need of a reliable and affordable red dot sight, I'd highly recommend the Aimpoint Pro.
One of the features I particularly appreciate is its precise aiming reticle. The 2 MOA dot size is standard for mid-range and CQB, offering the accuracy and versatility needed for various shooting scenarios. This precision has significantly improved my shooting experience.
Another aspect that stands out is its 'Always Ready & Always On' capability. The sight stays on continuously, running on a single 3V type 2L76 or DL1/3N battery. Remarkably, this battery lasts over three years, which means I don't have to worry about it dying at a critical moment.

Holosun AEMS - Best Lightweight
I recently got my hands on Holosun's latest AEMS red dot sight for a PSA AR15, and it's been a great optic upgrade for my small PDW AR15 setup.
The smaller profile of the AEMS is something I really appreciate. It gives the feel of a 509T but with a significantly larger viewing area, enhancing my field of view during shooting, and there is no large optic frame obstructing the view.
The 7075 T6 model is the best model they offer. The sight is fully protected with recessed buttons, making it robust enough to survive harsh field conditions. It's IPX8 rated, and while the AEMS Core version comes with standard non mil-spec aluminum housing at $100 less, it still offers great durability.
What stands out the most is that the optic can run on its solar failsafe with the super capacitor to run indefinitely without a battery installed.

Sig Sauer ROMEO 5 GEN 2 - Best For The Money
I've been loving the brand new Sig Romeo 5 GEN 2 on my PSA AR rifles without breaking the bank. While the generation 1 ROMEO 5 has been a very successful budget option red dot option for many AR15 users, and the GEN 2 is a much more polished version while staying at the same price ($120).
The extended battery life of the Sig Romeo 5 is another reason I highly recommend it. It runs up to 50,000 hours of battery life without the need to turn it off, which is incredibly efficient and reduces the hassle of frequent battery changes.
It's a robust coating and compact 1X20mm red dot sight and is, in my opinion, one of the best value red dot sight available for AR15s.
The turrets are now recessed without any caps so users can just pick up a shell casing and dial. As always, the ROMEO 5 is compatible with any Aimpoint Micro mount.
