Introducing the ultimate sighting solution for rifle enthusiasts: the Holosun HS510C Red Dot & HM3X Magnifier Combo. This powerhouse pairing brings together the precision of Holosun's HS510C Open Reflex Circle Dot Sight with the versatility of the HM3X Magnifier, creating a symbiotic duo that caters to both close-range and extended-range shooting.

The HS510C offers a generous open frame for a broad and unhindered field of view. Designed to be always on, its innovative solar cell utilizes ambient light for continuous operation, bolstered by a back-up battery for low-light conditions. Users will appreciate the option to swiftly toggle between the 65 MOA circle with a 2 MOA dot and the singular 2 MOA dot reticle, both projected by the same LED to eliminate the need for re-zeroing.

The HM3X Magnifier complements the red dot sight with its 3x magnification, bringing distant targets into clear focus. Its adjustable diopter and exceptional eye relief ensure a comfortable and rapid target acquisition. Durable and consistently reliable, this magnifier boasts a flip-to-side design, allowing shooters to seamlessly switch between magnified and unmagnified views. The Holosun HS510C Red Dot & HM3X Magnifier Combo is an unparalleled choice for diverse shooting disciplines, offering a level of versatility and performance that is second to none.

Price Match

We guarantee that we offer the best prices online.

If you come across another online retailer that sells the same item from the above manufacturer at a lower price plus shipping cost within one month of purchase, please let us know, and we'll refund the original payment for the difference in price.

For the guarantee to apply, the total order price of the item which includes shipping cost must be lower than what you paid us. For example, let's say you paid a total of $150 for an item on our site. If you see the same item advertised for $140 on another site but shipping cost is an additional $15, the guarantee DOES NOT apply since the total order price is $155.

On the other hand, if the same item is $140 but the shipping cost is an additional $5, the guarantee DOES apply since the total order price is $145 which is lower than what you paid us. The refund amount would be $5 for the difference. Please note we don't factor sales tax into the total order price when considering the guarantee. 

You can email us a link to the product on our website, as well as the link to that same product on our competitor's site within one month from your order date, to request for the partial refund. 

There are a few limitations on our price guarantee:

  • Items must be purchased from our site before requesting the Price Match guarantee
  • Promotions such as rebates and buy one, get one free offers are not eligible
  • The item must be in stock on the competitors website
  • The competitor must only be an online store and not have a physical retail location
  • The lower price cannot be found on an auction or market site like eBay, Amazon, Overstock, Wayfair, Jet, etc.
  • The competitor must be an Authorized Dealer or Retailer of that product
  • The Guarantee includes the total price of the item, but does not include sales tax
