Nightforce NX8 1 8x24mm F1 Capped Dark Earth FC DMx C663 UPC 847362022833
Product Description
The Nightforce® NX8 1-8x24mm F1 Capped Riflescope (SKU: C663 / UPC: 847362022833) represents the pinnacle of compact, low-power variable optical engineering purpose-built for tactical carbines, designated marksman systems, and lightweight modern sporting rifles. Delivering true 1x red-dot speed coupled with rapid 8x target identification and engagement, the NX8 F1 establishes class-leading versatility in a footprint measuring a mere 8.7 inches in overall length. Optimized around the daylight-bright, first-focal-plane FC-DMx reticle, this optical system provides immediate close-quarters situational awareness while equipping operators with an uncluttered 1 MRAD holdover grid for precision engagement out past 600 meters.
Engineered from solid bar-stock 6061-T6 aircraft-grade aluminum, the 30mm single-piece maintube provides maximum structural integrity and internal tracking stability under sustained multi-axis recoil impulses and severe field handling. The entire aluminum chassis is hardcoat anodized in Dark Earth to MIL-A-8625 Type III Class 2 specifications, ensuring exceptional wear resistance against abrasion, harsh cleaning solvents, and caustic chemical exposure. Internally, premium Japanese Extra-Low Dispersion (ED) glass elements are fully multi-coated to optimize light transmission, edge-to-edge optical resolution, and chromatic aberration control, encased within an O-ring sealed, nitrogen-purged housing impervious to thermal shock, sub-zero fogging, and deep water immersion.
Human engineering and rapid manipulation define the operational interface of the NX8 C663. Equipped with a factory-integrated, removable Power Throw Lever (PTL), magnification adjustments between 1x scanning and 8x positive identification are executed smoothly and instinctively under time pressure, even with heavy tactical gloves. The low-profile capped elevation and windage turrets track crisply in 0.2 MRAD click values with 30 MRAD of total travel, guarding against accidental mechanical displacement during vehicle operations, barrier transitions, or heavy brush navigation. The package includes protective rubber lens covers, a multi-tool for battery and zero calibration, a microfiber cleaning fob, and the screw-in throw lever, delivering a combat-proven optic ready for immediate duty staging.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Engineered for M1913 Picatinny rail mounting using quality 30mm scope mounts or rings (compatible with AR-15, AR-10, SR-25, SCAR 16S/17S, and lightweight precision bolt-action platforms). CRITICAL: Requires standard 30mm scope rings/cantilever mounts; NOT compatible with 34mm or 35mm optical mounts. When mounting on AR platforms, use a cantilever mount (1.54" standard or 1.93" upright NV/gas mask height) to achieve proper 3.7" eye relief without bridging between the upper receiver and handguard. Ensure base crossbolts are torqued strictly to manufacturer mount specifications (typically 45–65 in-lbs to Picatinny rails), and ring cap screws are evenly torqued in an X-pattern to 15–18 in-lbs dry (do not exceed 18 in-lbs to prevent tube binding).
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Degrease the mounting rail and inner ring surfaces with isopropyl alcohol; dry-fit the 30mm cantilever mount onto the flat-top upper receiver, strictly avoiding bridging onto the handguard.
- Place the NX8 optical tube into the lower ring cradles, install the ring caps loosely, and position the optic forward or aft to calibrate the optimal 3.7-inch eye relief in your natural cheek weld position.
- Level the reticle to the receiver using precision feeler gauges or bubble levels; apply ring screws dry or with a micro-drop of medium-strength threadlocker if specified by the mount maker, torquing evenly in an alternating X-pattern to 15–18 in-lbs.
- Install a fresh CR2032 lithium coin battery into the external illumination turret, verify daylight-bright illumination at maximum setting, and perform full mechanical tracking and dry-fire function checks before zeroing at 100 yards.
Key Features
- Compact 8.7-Inch Chassis: Minimizes snag hazards, reduces host weapon footprint, and optimizes balance on lightweight modern carbines.
- FC-DMx First Focal Plane Reticle: Daylight-bright 4 MRAD segmented circle at 1x transitions to an ultra-precise 0.2 MRAD center aiming dot with 1 MRAD elevation and wind holds at 8x magnification.
- Rugged 30mm 6061-T6 Monolithic Tube: Yields exceptional structural rigidity and provides 30 MRAD of elevation and windage adjustment range.
- Capped Low-Profile Turrets: Finger-adjustable 0.2 MRAD turrets sealed under knurled aluminum caps to prevent unintentional zero movement in rough duty environments.
- Removable Power Throw Lever (PTL): Facilitates instant, decisive power changes across the full 1-8x range under fluid tactical scenarios.
- Premium Japanese ED Optical Glass: Maximizes light gathering, edge-to-edge optical clarity, and accurate color rendition while eliminating chromatic fringe.
- Dark Earth Type III Hardcoat Anodizing: Delivers non-reflective camouflage matching military and modern sporting rifle earth-tone color palettes.
