Nightforce NX8 – 1-8x24mm F1 MRAD PTL FC-DMx Dark Earth Riflescope w/Capped E/W C663

The Nightforce NX8 1-8×24 F1 in Dark Earth is a first focal plane low power variable built for fast target acquisition and short to mid range shooting, offered here as the C663 with the FC-DMx reticle and capped elevation and windage turrets. It is a milliradian optic, so your holds, your corrections and your spotter calls all live in the same language. At 8.75 inches and 17 ounces it adds almost nothing to a rifle while giving up almost nothing in capability.

What the Nightforce NX8 C663 is, and who should run it

This is the MRAD answer for shooters who think in mils and want one optic that covers both ends of a realistic engagement. At 1x you shoot with both eyes open and treat it like a red dot, and by the time you reach 8x you can identify and engage targets well beyond what most shooters expect from a compact optic.

It suits carbine shooters, competitors and anyone who trains with mil based data and has no interest in translating between systems in the middle of a stage or a hunt. The capped turrets say plainly that this scope is built to be held rather than dialed, which is exactly right for the way a low power variable actually gets used.

Key features of the Nightforce NX8 in MRAD

• FC-DMx reticle in MRAD: a first focal plane design whose subtensions stay true at every magnification setting.
• Capped elevation and windage: the caps keep your zero protected from gear, slings and hard transport.
• PTL power throw lever: a fast, positive grab point for moving between 1x and 8x without losing your position.
• One piece 6061-T6 tube: machined from solid aircraft grade aluminum bar stock, two to three times thicker than lesser scopes.
• Hand matched glass: lenses aligned through the optical indexing process for the highest possible optical performance.
• Compact and light: 8.75 inches long and 17 ounces, so rail space and rifle balance stay where you want them.

Specifications in plain language

A 1-8x magnification range paired with a 24mm objective is what makes the Nightforce NX8 so small, and the first focal plane design is what makes that small package genuinely useful. Because the reticle grows and shrinks with the image, a mil is a mil at 3x and at 8x, so the holdover marks in the FC-DMx never lie to you no matter where the power ring happens to sit.

Durability is where Nightforce made its reputation, and the tube is the proof. Solid bar stock 6061-T6 aluminum, machined in one piece and left far thicker than the industry norm, delivers greater thermal stability, a consistent zero and a virtually impervious shield for the precision glass inside. Line it up against the rest of our optics and scopes and the difference in construction is obvious.

Setup, care and getting the most from it

Mount it level in quality rings, torque everything to specification, and confirm your eye relief at 8x rather than at 1x, since that is where a poor mounting position hurts you most. Zero at the distance you shoot most often, then build a simple mil based holdover card and confirm it on steel instead of trusting a calculator. Mils make that card short and easy to memorize, which is the whole point of choosing this configuration.

Maintenance is minimal. Keep the caps on when you are not adjusting, use a lens pen or a blower before any cloth touches the glass, and check your mount screws periodically, because a loose ring will always be the first thing to move. Everything else on this scope is sealed, machined and left alone.

Tough, honest and light enough that you forget it is there, this one belongs on a rifle that actually gets used. Ships direct to your door, no FFL required.
