Why choose Athena Precision red dot plates over others? What makes them the best?

Athena Precision plates are CNC-machined from hardened, heat-treated steel with tight tolerances, field-tested for duty and competition, made in the USA by a veteran-owned team, and backed by a lifetime warranty—built to hold zero when it matters.

What materials are Athena Precision plates made from?

Every plate is cut from hardened, heat-treated steel to maximize strength, thread integrity, and durability compared to aluminum or standard steel.

Which optic footprints do Athena Precision plates support?

We support popular footprints including Holosun 509T, Holosun EPS, Trijicon RMR, Leupold DeltaPoint Pro (DPP), Aimpoint ACRO, and more. Check the Plate Finder for your exact match.

Are Athena Precision plates compatible with different firearm models and optics?

Yes. We cover major brands like Glock, Sig Sauer, Smith & Wesson, FN, Staccato, HK, Vortex, Trijicon, Holosun, and others. Use the Plate Finder to confirm fitment for your firearm and optic.

How do Athena Precision plates maintain zero and ensure superior accuracy?

Precision CNC tolerances, hardened steel, and a locked-in interface (bosses/screw posts) prevent movement under recoil so your point of aim stays true after high round counts, impacts, and harsh conditions.

Can I install Athena Precision optic plates myself?

Yes. Installation is straightforward with included hardware. We recommend a small amount of thread locker (e.g., Loctite 222) and following the included instructions for proper torque and cure time.

Where are Athena Precision products made?

Engineered, manufactured, finished, and shipped from our facility in Salt Lake City, Utah. We are a veteran-owned American company.

What warranty do you offer?

All Athena Precision products include a lifetime warranty against material and manufacturing defects. We also accept returns on new, unused items within a reasonable period—contact support for help.

How low do Athena Precision red dot plates sit?

Our designs sit lower than most plates—often compared to a milled-slide feel—for faster presentation and better co-witness options. Exact thickness varies by model; see each product description.

Who uses Athena Precision products?

Trusted by law enforcement, military, competition shooters, and concealed carriers—plus any serious shooter who demands reliability and long-term zero retention.

Amazing Product

As a French shooter, I was looking for a plate for my G19 allowing me to mount the 509T on it. After a fair bit of searches, Athena was the only US site without an issue sending it to me accross the pond.

Product is of very high quality, and the shape of it allow the 509T to be mounted fairly low on the slide (nearly half a cm less that the regular RMR+509T adapter).

Shooting in IPSC, the setup have taken around 1000 rounds so far with great success. Would I need another mounting plate solution for another handgun in the future, I would definitely go through Athena Precision. Great quality, great success.

Rock Solid Mounting Solution

I received my order much faster than I expected, and I have to say that I’m very impressed with the quality of this Glock 509T mount. This is the lowest mount I could find, and it places the Holosun 509T all the way down against the slide. The TAG Precision Tall sights that I installed, make a perfect 1/3rd cowitness with this mount. I couldn’t be happier with how this all worked out. I have my Glock 21 Gen 5 tuned to run very heavy 45 Super loads, and have no doubt that this mount will provide a lifetime of trouble free shooting.
