Discoveryopt MS 4–16×44 SFIR Side Parallax Riflescope – detailed product overview

The Discovery Optics MS 4–16×44 SFIR is a value-for-money entry-level scope: a wide (4–16×) magnification range, 44 mm objective lens, lateral parallax, and illuminated MOA reticle — all at a price point where many competitors still require compromises. The 30 mm tube provides a larger internal adjustment range, and full multi-layer (FMC) coatings ensure a clear, high-contrast image in both daylight and low light. The construction is nitrogen-filled, shock-proof, waterproof, and fog-proof.

Main technical data

• Magnification: 4–16×

• Lens: 44mm

• Tube: 30 mm, one-piece aluminum

• Parallax: side adjuster, min. 10 yards (~9 m) – ∞

• Reticle: glass-etched MOA graduation, illuminated (with step adjustment)

• Click value: 1/4 MOA / click

• Turrets: exposed, lockable turrets, with resettable zero point, with well-felt clicks

• Eye relief: ~8–9 cm (depending on magnification)

• Design: nitrogen, shock/water/fog resistant

What do you know in practice?

• Image quality: thanks to the FMC coating, it provides a clear, contrasting image, the 44 mm front lens ensures good light collection.

• Usability: The 4x lower magnification provides quick target acquisition at close range, while the 16x upper end is sufficient for fine aiming at medium to long range. The lateral parallax provides quick and accurate focus/parallax correction from 10 yards.

• Mechanics: 1/4 MOA scale, lockable turrets repeat accurately; 30 mm tube provides ample adjustment range. Robust construction stands up to use.

Recommended use

• Airgun (PCP/spring) and .22 LR: excellent for indoor 10m training to outdoor plinking due to the 10 yard parallax minimum.

• Small and medium caliber hunting / varmint: balanced at 100–300 m; illuminated reticle helps on dark backgrounds.

• Hobby and sports shooting: versatile training scope, good value for money for beginners and advanced shooters.

Who do I recommend it to?

• For beginner-intermediate shooters looking for an "all-rounder" optic at a fair price, without basic compromises (lateral parallax, illumination, lockable turrets, 30 mm tube).

• For price-sensitive hunters/sport shooters who value reliable mechanics and a clear image, but don't want to pay a premium price.

Competitive advantages in brief

• Side parallax + lighting is not always a default in this price range.

• 30 mm tube – more internal correction than 1” (25.4 mm) tubes.

• Lockable, resettable turrets – quick adjustment, protected against accidental unscrewing.

• Price-value – the amount of features/usability puts it at the forefront of the category.

Typical price level

In international supply, the price range is typically entry-level to mid-range: ~120–130 USD (approx. 110–120 EUR), in EU distribution the gross final price can usually be higher due to local taxes/logistics (often in the range of ~140–160 EUR).
