AGM Adder V2 LRF 50-640 Thermal Rifle Scope

The AGM Adder V2 LRF 50-640 is the middle tier of AGM's flagship Adder V2 LRF thermal rifle scope family — the step up from the 35-384 LRF into a 640-class sensor, paired with a 50 mm objective lens for added reach and the same Adder V2 platform that defines the line: a fully integrated 1,000-yard laser rangefinder hidden inside the front lens, sub-15 mK NETD sensor, AGM's first shutterless NUC system, 2,560×2,560 semi-circular OLED display, integrated ballistic calculator, and the American-made ADM Recon QD mount included.

For most Adder V2 LRF buyers, this is the right scope. The 640 sensor delivers the image quality the platform is built around. The 3.5×–26× magnification range covers most North American hunting from close brush to long pasture. The 50 mm lens balances reach against weight. And the price sits between the entry-tier 35-384 and the 1280-sensor flagship 60-1280 without giving up anything the Adder V2 platform is known for.

Where the 50-640 LRF fits in the Adder V2 family

The Adder V2 LRF series is a tiered family on a shared platform. Same internal LRF, same shutterless NUC, same 2,560×2,560 display, same UI, same 64 GB onboard storage, same dual-battery system, same ADM Recon QD mount. What changes between tiers is sensor resolution and lens size.

• Adder V2 LRF 35-384 — 384×288 sensor, 35 mm lens, 4×–24× zoom. Entry tier, with the highest base magnification in the line.
• Adder V2 LRF 50-640 — 640×512 sensor, 50 mm lens, 3.5×–26× zoom. The versatile middle of the line.
• Adder V2 LRF 60-1280 — 1280×1024 sensor, 60 mm lens. The flagship — maximum resolution for hardest-target identification at extreme range.

Step up from the 35-384 LRF to the 50-640 LRF when you want a 640 sensor for finer detail and added reach. Step up from the 50-640 LRF to the 60-1280 LRF when 1280 image quality at extreme range is the deciding factor.

Why the 640 sensor matters

A 640×512 sensor has roughly 2.3× the pixel count of a 384×288 sensor — more pixels collecting heat data across the same scene means finer thermal resolution, better target identification at distance, and cleaner edge definition on warm bodies in difficult conditions. On the Adder V2 LRF 50-640, that 640 sensor pairs with a 50 mm lens to deliver the right balance of detail and reach for most hunting use cases: close enough for hogs in brush, far enough for coyotes across cut fields.

The integrated LRF — and why the design matters

The first thing to notice about the Adder V2 LRF 50-640 is what you don't see. Most thermal scopes with built-in rangefinders bolt the LRF housing onto the outside of the scope — a separate module attached to the side or top. AGM took a different approach. Open the magnetic lens cap on the Adder V2 LRF and the new 1,000-yard laser rangefinder is tucked inside the front lens itself, virtually invisible from any angle but head-on.

This is a first in the thermal market, and it matters for more than just looks. An LRF inside the lens means no added profile, no extra rail real estate consumed, no separate module to align or worry about damaging. The integration is functionally cleaner than what most thermal scopes offer.

What you get with the Adder V2 LRF 50-640

• 640×512 thermal sensor with 12 μm pixel pitch. AGM's current 640/12 sensor generation — finer detail and better target identification at distance than 384-class scopes.
• Sub-15 mK NETD. Industry-leading thermal sensitivity. Sharp contrast and clean edge definition even in fog, light rain, marginal heat conditions, or any situation where target-to-background heat difference is small.
• 50 mm objective lens. Sized to match the 640 sensor for the best balance of field of view and reach.
• 3.5× base magnification, 3.5×–26× total range with digital zoom. Supports both full-step and 0.5× incremental zoom adjustments — no wasted sections of the magnification range.
• Fully integrated 1,000-yard laser rangefinder tucked inside the front lens — a first in the thermal market. No external module bolted on.
• Onboard ballistic calculator with five user-saved profiles for different cartridges or loads. Range a target, get drop data instantly.
• 2,560×2,560 semi-circular OLED micro display. AGM's highest-resolution display, with a redesigned semi-circular interface that puts battery life, magnification, range, time, and vertical/horizontal pitch scale readouts where you can see them without losing the target.
• Shutterless NUC system. AGM's first shutterless non-uniformity correction — no mechanical shutter blink interrupting your view during recalibration.
• Pitch scale activation. Vertical and horizontal pitch scale readout for awareness of rifle cant.
• Picture-in-Picture mode with target zoom alongside the wider field of view.
• 64 GB onboard storage with media albums viewable on-device.

• 1,000 g recoil rating. Rated for big-bore calibers including .375 H&H.
• IP67-rated waterproof and shockproof construction.
• 50 Hz refresh rate for smooth real-time imaging on moving targets.
• ADM one-piece Recon 30 mm QD mount included ($220 value). American-made, field-proven, designed around the Adder V2's 30 mm tube housing.

Frequently asked questions

Where does the 50-640 LRF fit in the Adder V2 LRF family?

It's the middle tier and the most versatile choice in the line. The "50" is the 50 mm objective lens; the "640" is the 640×512 sensor. Below it sits the 35-384 LRF (384 entry tier); above it sits the 60-1280 LRF (1280 flagship).

What's the difference between the Adder V2 LRF 50-640 and the 35-384?

The 50-640 steps up to a 640×512 sensor with a 50 mm lens (vs. the 384×288 sensor and 35 mm lens on the 35-384). The 640 sensor delivers finer thermal detail and better target identification at distance, and the 50 mm lens gives you added reach. Both share the full Adder V2 LRF platform — same display, integrated LRF, ballistic calculator, shutterless NUC, mount system. Step up to the 50-640 when you want the image-quality jump and added reach.

What's the difference between the 50-640 and the 60-1280?

The 50-640 has a 640×512 sensor and 50 mm lens. The 60-1280 steps up to a 1280×1024 sensor — roughly four times the pixel count — with a 60 mm lens for added reach. Choose the 60-1280 when image resolution at extreme range is the deciding factor. Choose the 50-640 when 640 image quality is enough for your hunting and the price step doesn't earn its keep.

What's special about the integrated LRF design?

The 1,000-yard laser rangefinder is built into the front lens itself, behind the magnetic lens cap — not bolted on as an external module like most thermal scopes with rangefinders. This is a first in the thermal market. The result is a cleaner profile, no added rail real estate consumed, and no separate housing to align or protect.

What is the shutterless NUC system and why does it matter?

Most thermal scopes use a mechanical shutter that periodically blinks across the sensor to recalibrate the image (non-uniformity correction, or NUC). That blink interrupts your view — sometimes at the worst possible moment. The Adder V2 is AGM's first scope with shutterless NUC, which recalibrates without the mechanical shutter blink. Seamless, quiet, uninterrupted viewing.

Is the 50-640 a good thermal scope for hog hunting?

Yes — and for most thermal hunters it's the right Adder V2. The 640 sensor handles hog body heat with detail to spare, the 3.5× base and 50 mm lens deliver a wide enough field of view to find and track hogs through brush, and the 26× top end gives you the reach for shots across open fields. The integrated LRF and ballistic calculator handle ranging and dial-in.

What's the 0.5× incremental zoom and why does it matter?

The Adder V2 lets you switch between full-step zoom and 0.5× incremental zoom adjustments. Most thermal scopes step through zoom in fixed increments, which can leave you stuck between two zoom levels neither of which is quite right for your target. The 0.5× incremental mode lets you dial in finer adjustments — no wasted sections of the magnification range.

How accurate is the integrated LRF?

The Adder V2 LRF ranges to 1,000 yards. The ballistic calculator uses your input bullet velocity and ballistic coefficient to compute drop for the ranged distance. Five user profiles let you save settings for different cartridges or loads.

Will the Adder V2 LRF 50-640 hold up to big-bore calibers?

Yes. The Adder V2 LRF is rated to 1,000 g of recoil impact and AGM specifies it as appropriate for calibers up to .375 H&H.

What mount comes with it?

A field-proven American-made ADM (American Defense Manufacturing) one-piece Recon 30 mm QD mount — a $220 value, included with the scope.

What's the warranty?

AGM backs the Adder V2 LRF 50-640 with their 5-year manufacturer warranty.
