Review: U.S. Optics FDN 25X Tactical Riflescope

June 7th, 2021

Here at GunSpot, we were lucky enough to meet the folks at U.S. Optics at SHOT Show 2020, and since then they have sent us an FDN 25X scope for review. This is their top-of-the-line, maximum power long-distance scope. Naturally, we needed a high-powered rifle to pair with it, so we chose the Loaded M1A Precision rifle in 6.5 Creedmoor.

The FDN 25X is a 5-25 power scope with a 34mm tube. The quality of this scope is fantastic. It is highly durable, and this is apparent as soon as you get your hands on it. I feel pretty confident to say that you could take this scope and beat someone with it in self-defense, put it back on the rifle and it would not be broken and would still hold its zero. This scope is just over 2 lbs., so it is a thick-walled and dense optic.

The 52mm objective lens and the 34mm tube allow for plenty of light transmissions back to the user’s eye.

This scope features a 52mm objective, 6061-T6 aluminum 34mm tube, and a low-profile ER3K elevation knob with a zero stop. It also has an ergonomic capped US#1 windage knob. This scope does have an integrated illuminated reticle and parallax knob. Something to note is the fact that the zoom on this is a smooth rapid adjustable 180-degree magnification throw. Scopes with a power adjustment from 5-25 can have some pretty stiff magnification sometimes, but this one is consistently smooth all the way through.

Custom Grade

This scope has a starting price tag of around $3,499, but depending on the options you choose the price can go up. This brings me to another point I’d like to mention about this scope. You can customize this scope for you in almost any way that you want. You can choose from any Cerakote number that you want for a color. So, if there’s some custom color you want you can order your scope in that color from U.S. Optics.

The elevation knob on the FDN 25X is a beefy knob that is great for hands that are cold or in gloves.

This is cool because putting Cerakote on a scope can be a challenge. Scopes have gases inside the optic, and it makes it a challenge for the Cerakote process.

There are 11 reticle options you can choose from on their website. We got ours in with the JVCR reticle. The reticle options they have available right now are as follows:

  • GAP
  • GENIIXR
  • MGR
  • MPR
  • JVCR
  • IGR
  • MDMOA
  • H59
  • H102
  • TREMOR3
  • PR2

So, there should be a reticle option for everyone out there!

Scope mounted on M1A rifle
The Loaded M1A Loaded Precision rifle is a great platform for a scope because of its adjustable stock.

There are three illumination options for the reticle including red, green and blue. There are also options for elevation, windage and even your eyepiece.

The Why

There is no doubt in my mind that you can find scopes cheaper than this one at the same power option. But, this scope from U.S. Optics is a custom scope and it’s handmade here in the United States.

Testing the FDN 25X on the range
LaVelle was able to shoot with the FDN 25X and the M1A rifle all the way out to 800 yards for our video test.

We did shoot it on the M1A Loaded Precision rifle in 6.5 Creedmoor and were able to shoot targets over 1,000 yards. On the video, we shot at 800 consistently. In fact, the FDN 25X is able to acquire targets out to 2,000 yards, so there will be no issues of this scope lacking power.

A perfect match: the U.S. Optics FDN 25X perched atop the Springfield Armory M1A Loaded Precision rifle.

The knobs on this scope are great; in particular, the extremely large beefy elevation knob is fantastic. The elevation knob is used the most when applying DOPE since a wide group of shooters prefers to just hold their wind adjustments instead of dialing them.

The elevation knob being so large is great for gloved hands and hold hands. Having all that material is great to grab onto and it lets you easily see the numbers as you turn the knob. U.S. Optics also has a really great way of resetting the 0 of the knobs. On the top, there are two small set screws in the elevation knob and when you take those out it lets you lift the cap off so you can move your 0 back to the proper middle position after you sight in your rifle.

Conclusion

The FDN 25X is a custom scope and it is made for some of the top shooters in the world. That’s right, I said in the world. U.S. Optics has customers who use these scopes for competitions, and their livelihoods depend on the dependability and accuracy of these scopes.

Setting up rifle and scope for accuracy testing
For the review of the FDN 25X, Lavelle used Winchester Deer Season XP 6.5 Creedmoor ammunition.

That being said, since it’s a custom scope tailored to you, and some of the best shooters in the world choose this scope, it’s going to be higher in price range than some others out there. But if you shoot a lot and you need a custom reticle, illumination color and scope color to go with your rifle, this is without a doubt a good one. Plus, it’s made right here in the United States.
