Nocpix Rico 2 L42R LRF Thermal Rifle Scope

The Nocpix Rico 2 L42R LRF is the entry point into the Rico 2 family — Nocpix's flagship thermal weapon sight platform. It pairs a 384×288 thermal sensor with a 42 mm germanium objective lens, an integrated 1,200-yard laser rangefinder, and the same Rico 2 family-wide platform that powers the higher-tier S75R, H75R, and H50R: a 2560×2560 round AMOLED display, ballistic calculator, recoil-activated video, magnetic charging, and a quick-detach mount. If you want into the Rico 2 line at its most accessible price, this is it.

The L42R is built for hunters who want Rico 2 platform features and ballistic-grade ranging on a 384 sensor. It fits hog hunters working Texas brush country, coyote callers in open fields, and predator and ranch operators who want one tool that ranges, calculates a shot, and records the kill — without stepping into the price of the 640 or 1280 sensor builds.

The Rico 2 family — how the L42R fits

Nocpix structured the Rico 2 series as a four-model tiered family on a shared platform. The naming code tells you the tier: L = 384 sensor, H = 640 sensor, S = 1280 sensor. The number that follows is the objective lens size in millimeters.

• L42R — 384×288 sensor, 42 mm lens. Entry into the Rico 2 platform; close-to-mid range work where a 384 is enough.
• H50R — 640×512 sensor, 50 mm lens. The versatile middle of the line — best balance of magnification, field of view, and reach for medium-range hunting.
• H75R — 640×512 sensor, 75 mm lens. 640 image quality at extreme range; long-distance predator work where reach matters most.
• S75R — 1280×1024 sensor at 60 Hz, 75 mm lens, stepless digital zoom to 30×. The top of the line — maximum resolution and refinement for precision long-range identification.

Step up from the L42R to the H50R when you want a 640 sensor for finer detail and the medium-range versatility a 50 mm lens delivers. Stay with the L42R when entry into the Rico 2 platform at the lowest price is the deciding factor.

What you get with the L42R

• 384×288 thermal sensor with 12 μm pixel pitch. Reliable target detection and identification across hog, predator, and ranch use cases. The 384 sensor class is the most popular in modern thermal hunting — cost-effective and capable.
• NETD ≤18 mK. Sharp thermal contrast for cleanly distinguishing animals from background heat signatures, even in dense fog, light rain, or marginal heat conditions where less-sensitive sensors start to soften.
• 42 mm germanium objective. Sized to match the 384 sensor and deliver a 2,400-yard detection range — enough reach to identify heat signatures well ahead of your quarry.
• 4× base magnification, up to 16× with digital zoom. Scan wide at base power, then zoom in tight when you're working a target. The Rico 2's smooth digital zoom keeps the image transitions clean.
• 60 Hz refresh rate. Real-time imaging on moving targets — coyotes coming in to a call, hogs moving through brush — without the smear that lower refresh rates can show.
• Built-in 1,200-yard laser rangefinder + ballistic calculator. Input bullet velocity and ballistic coefficient; the system calculates drop based on ranged distance. Confirm distance and dial a correction without ever pulling a second device.
• 2560×2560 round AMOLED display. The same high-resolution display used on every Rico 2 model — crisp, comfortable, and immersive across long sits.
• Picture-in-Picture mode for keeping your zoomed target view alongside the wider field of view.
• Recoil-activated video and onboard recording so you don't miss a kill capture in the heat of the shot.
• Magnetic charging port for fast, intuitive battery recharges; spare battery included.
• Quick-detach mounting system for fast install and removal — no zero loss when you take the optic off the rifle and put it back on.
• Five-hour battery life keeps you running through long sits and all-night predator sessions.

Who the L42R is built for

• Hog hunters working Texas brush country who want a 384 with built-in ranging and ballistic dial-in
• Coyote callers in open fields who need to range a charging dog and put a fast, accurate shot on it
• Predator and ranch operators who want one optic that ranges, calculates, and records
• Buyers who want into the Rico 2 platform — display, LRF, ballistic calculator, mount system — at the entry-tier price
• Hunters cross-shopping the Rico 2 line who don't need the reach or resolution of the H or S tiers

Frequently asked questions

Where does the L42R fit in the Rico 2 family?

The L42R is the entry tier of the four-model Rico 2 series. The "L" in the model name signals the 384 sensor tier; the "42" is the 42 mm objective lens size. Above it sit the H50R and H75R (640 sensor) and the S75R (1280 sensor flagship).

What's the difference between the L42R and the H50R?

The L42R has a 384×288 sensor and a 42 mm lens, with 2,400 yd detection. The H50R steps up to a 640×512 sensor and a 50 mm lens, with detection out to approximately 2,800 yd. Both share the Rico 2 platform — same display, same LRF, same ballistic calculator, same mount system. Choose the L42R for entry-tier pricing and 384 image quality; step up to the H50R for finer 640 detail and added reach.

Is the L42R a good thermal scope for hog hunting?

Yes. The 384 sensor handles hog body heat cleanly, the 4× base magnification and 16× digital zoom cover close-to-mid range engagements, the built-in LRF and ballistic calculator handle ranging and dial-in, and the 60 Hz refresh rate keeps moving targets smooth. The recoil-activated video also captures the shot without you needing to start a recording.

How accurate is the laser rangefinder?

The Rico 2 family's integrated LRF ranges to 1,200 yards. Combined with the ballistic calculator — once you input your bullet's muzzle velocity and ballistic coefficient — the system gives you drop data for the ranged distance.

What battery does the L42R use and how long does it last?

The L42R uses Nocpix's rechargeable battery system with a magnetic charging port. Runtime is up to approximately 5 hours on a charge, and a spare battery is included with the scope.

Does the L42R record video?

Yes. Onboard recording is included, with recoil-activated video that automatically starts capture when the rifle fires — so the kill is recorded without a manual press at the moment of the shot.

Will the L42R hold zero through recoil?

Yes. The Rico 2 platform's quick-detach mount system is engineered to return to zero, so the optic can be removed and reinstalled without losing zero. The L42R itself is built to withstand recoil, rain, and temperature extremes.

What's the difference between the Rico 2 L42R and the original Rico (Gen 1)?

The Rico 2 family upgrades the display to a 2560×2560 round AMOLED, refines the LRF and ballistic calculator integration, adds magnetic charging, and ships with the spare battery and recoil-mitigating quick-detach mount system. The Rico 2 is Nocpix's current flagship platform.

What's the warranty?

Nocpix backs the Rico 2 L42R with their standard manufacturer warranty.
