Discoveryopt LHD-NV 4-16×44 SFIR SFP – Riflescope for Hunters and Precision Shooters
The Discoveryopt LHD-NV 4-16×44 SFIR SFP is part of the manufacturer's new-generation LHD series. The LHD abbreviation stands for Lightweight High Definition – the goal being a riflescope that combines outstanding image quality for its price, reliable mechanics, and a design suited for real-world field use.
Optics and Image Quality
The scope uses a fully multi-coated lens system that maximises light transmission and reduces flare. The 44mm objective lens gathers enough light for a clear, high-contrast image even at dusk. The 4–16x magnification range allows flexible use: the lower settings enable fast target acquisition, while the higher settings allow detailed observation and precise shot placement.
SFP Reticle and Illumination
The scope uses a Second Focal Plane (SFP) configuration, meaning the reticle size remains constant regardless of magnification. This is particularly advantageous in hunting situations where fast target acquisition is needed and a clean, uncluttered sight picture is more important than consistent reticle subtensions across all magnifications. The reticle is engraved – not painted – ensuring a durable and wear-resistant appearance. The SFIR designation refers to partial red illumination: only the central element of the reticle lights up, which is especially useful for high-contrast aiming in low-light conditions. Illumination intensity is adjustable in multiple steps.
Side Parallax and Adjustments
Parallax compensation is adjustable via a side wheel, from 15 yards to infinity. This solution allows quick and convenient correction without the shooter having to take their eye off the rifle. The click value is 1/4 MOA (approximately 7.3mm per 100 metres), providing sufficient precision for accurate zeroing. Both elevation and windage adjustment ranges are 90 MOA each, giving adequate room for zeroing most rifle and scope combinations.
Mechanics and Build
The 30mm one-piece tube is made from aircraft-grade aluminium, providing both rigidity and a reasonable weight. The housing is O-ring sealed and nitrogen purged, making it waterproof and fogproof. The manufacturer has validated its shock resistance through extensive testing – like other LHD series models, the scope can withstand recoil from .50 BMG. The scope weighs 758g and measures 352mm in length, making it well suited for most hunting or precision rifles.
Night Vision Compatibility
The "NV" designation in the model name and the ocular design suggest the scope is likely compatible with night vision attachments. However, no confirmed manufacturer documentation is available on this, so this feature should be taken into consideration with some reservation when making a purchase decision.
What the Community Says
International forum opinions about the Discovery Optics LHD series (Rimfire Central, Hard Air Magazine Community) consistently highlight surprisingly good optical quality for the price, clear and high-contrast images, and reliable return to zero. However, some users note that quality control is not entirely consistent, and occasional variation between individual units can occur. Access to service also depends on where the product was purchased – it is advisable to buy from a reputable dealer.
Who Is This Scope For?
The Discoveryopt LHD-NV 4-16×44 SFIR SFP is primarily recommended for hunters and sport shooters who need reliable, clear optics at medium to long range (50–600 metres), and who value side parallax correction, an illuminated reticle, and a robust, weather-resistant build – all at a competitive price. It is particularly well suited to deer, roe deer or predator hunting rifles, but also holds its own in precision sport shooting applications.
