Delta Optical Javelin 3.5-21x50 FFP

• 3.5-21x magnification range: Covers everything from closer positional stages to deliberate long-range work, so the scope stays useful on precision rifles and designated marksman setups without forcing a compromise toward either end of the distance spectrum.
• First focal plane reticle: The reticle scales with magnification, keeping holdover and windage references consistent at any power. That matters in practical shooting, where corrections often need to be made quickly rather than only at one preset magnification.
• 50 mm objective with ED glass: The larger objective and ED glass help maintain a bright, well-defined image with good contrast, making small target details easier to read in mixed light and at higher magnification.
• Tactical turrets with Zero Stop: The exposed turret layout supports frequent dialing, while the Zero Stop gives a fast, repeatable return to the base zero after elevation changes for different distances.
• 34 mm tube and 29 mrad adjustment range: The large tube provides the internal travel needed for extended-distance shooting and gives more flexibility when pairing the scope with modern precision rifle cartridges and mounting setups.

About the Delta Optical Javelin Series

Delta Optical Javelin riflescopes sit in the brand's tactical and sport-shooting segment, with the series currently including 3.5-21x50 and 4.5-30x56 models. The line is built around first focal plane reticles, giving shooters usable subtensions throughout the magnification range rather than at only one setting. That makes the series especially relevant for practical long-range disciplines, where holdovers, wind calls and rapid corrections are part of normal use.

Across the series, Delta Optical pairs this layout with ED glass and an illuminated reticle center, aiming for a clear sight picture and better reticle visibility against dark backgrounds or in uneven light. Reticle options in the Javelin family include SKR-1, MKR-1, SMR-1, SMR-2 and 2D, reflecting the series' focus on different shooting styles, from PRS-type use to more specialized competition formats. In practical terms, the Javelin series is designed for shooters who want a modern tactical optic with meaningful reticle references, broad elevation capability and a configuration suited to precision rifles rather than a lightweight hunting scope format.

About the Delta Optical Javelin 3.5-21x50 FFP

The Delta Optical Javelin 3.5-21x50 FFP is configured for shooters who need one riflescope to cover both mid-range engagements and more deliberate long-range work. Its 3.5-21x magnification range gives enough low-end field awareness for closer targets while still providing the image scale needed for precise shot placement at distance. The 50.00 mm objective supports a bright image, and the use of ED glass in the Javelin line helps preserve contrast and target definition when magnification is pushed higher.

This model uses a first focal plane reticle, so the reticle's measuring and correction references remain proportionally correct at every magnification setting. For practical field shooting, that means holdovers and wind calls can be applied without first returning to one exact power. The illuminated red reticle adds visibility when the target or background reduces contrast, while the parallax adjustment from 10 m to infinity helps sharpen the image and reduce aiming error across a wide range of distances.

Mechanically, the scope is built around a 34 mm tube with 29.00 mrad of elevation and windage adjustment, giving the internal travel expected for modern long-range setups. The tactical turrets are intended for regular dialing rather than occasional zeroing, and the Zero Stop system makes it easier to return quickly to the established zero after multiple elevation changes. With a length of 353.00 mm, weight of 890.00 g, nitrogen filling, and waterproof, fogproof and shockproof construction, the Javelin 3.5-21x50 FFP is suited to demanding range use and field conditions where repeatability matters as much as optical clarity.

About Delta Optical

Delta Optical traces its beginnings to 1989, when it opened an optics shop for enthusiasts. The company is based in Nowe Osiny, near Mińsk Mazowiecki, Poland, and serves users across astronomy, biology, hunting and shooting. That broad optics background helps explain why its catalog covers both observation equipment and aiming optics rather than focusing on only one niche.

Within shooting optics, Delta Optical's riflescope lines include Titanium, Stryker and Hornet. The company describes its sporting scopes as using proprietary reticles and anti-reflective coatings, showing a focus on practical optical performance rather than cosmetic differentiation. In the riflescope category, Delta Optical has built a reputation around offering purpose-specific models for hunting, tactical shooting and target use, with product families that separate lightweight field scopes from more adjustment-focused precision optics such as the Javelin and Stryker lines.
