The Delta Titanium 4-24×50 HD offers not only precision and durability but gives the shooter a magnification range that is extremely versatile for short to long-distance hunting and now comes with interchangeable turrets! This gives you the option of having tactical style dial-able turrets or having the classic capped turrets, or a combination of both!
The Delta Titanium 4-24×50 HD gives the shooter an impressive total adjustment range of 100 MOA, both vertically and horizontally which is massive out of a 30mm tube.
This really is a Multi-purpose riflescope for both long-distance shooters and hunters alike.
A sufficient magnification range makes this riflescope practical for many hunters across all continents. The parallax adjustment side-knob with a range from 10m to infinity will be greatly appreciated by sports shooters. There are two reticles available, all with an illuminated central dot: 4A SB and Di MD.
The 4A SB reticle is based on the classic Delta Optical 4AS reticle with specially designed ballistic markers. The reticle is calibrated for the magnification of 12x and a distance of 100m.
The markers are located under the central illuminated dot, the distance between each marker is 7cm. They allow making quick and fine adjustments when shooting at distances from 150 to 300m with an initial velocity of 800-900 m/s. For example, with a weapon (308 WIN, a 10.7 g bullet, 820 m/s) zeroed at a distance of 100m, one would need to use the second marker below the aiming point (14cm compensation) in order to shoot at a distance of 200m.
Other bullets with an initial velocity of about 900 m/s will fall about 1-3 cm above the aiming point, while slower projectiles (initial speed of about 800 m/s) will hit about 1-3 cm below the target.
The ends of the horizontal markers can be used for wind corrections. The first marker located 7cm below the central illuminated dot is 9cm long, while the remaining are each 18cm long.

What exactly does “replaceable MOA turrets” mean, and why is it useful?
This scope includes two sets of turrets that can be swapped: traditional capped turrets for hunting or everyday carry, and exposed tactical turrets with zero‑stop and clear markings for long-range precision shooting.
What is the total adjustment range of this scope?
It offers approximately 100 MOA of vertical and horizontal adjustment, allowing engagement of extreme ranges without exhausting the internal adjustment travel.
How does the parallax adjustment system function?
The side focus knob adjusts parallax from 10 m to infinity, ensuring the reticle and target stay in the same focal plane for accurate aiming at both short and long distances.
What is the reticle calibration designed around?
The 4A‑SB reticle is calibrated at 12× magnification and 100 m, providing ballistic markers spaced for quick holdover without relying solely on turret dialing.
How are ballistic hold markers defined and used?
Markers under the illuminated dot are spaced to correspond to common ballistic trajectories, allowing quick elevation compensation and horizontal wind corrections.
What is the optical performance like at high magnification?
HD glass with fully multi-coated lenses delivers bright, high-contrast images with sharp resolution, maintaining clarity and detail at maximum magnification.
How consistent is eye relief across the zoom range?
Eye relief remains between 80–98 mm, providing comfortable viewing and minimizing the risk of scope-eye contact throughout the magnification range.
What is the benefit of a second focal plane reticle in this design?
The reticle maintains a fixed size across magnifications, keeping ballistic markers consistent at 12× for rapid reference and easier target acquisition.
How does the 50 mm objective lens improve performance?
It gathers more light than smaller objectives, enhancing brightness, contrast, and detail resolution at high magnification and low-light conditions.
What is the advantage of switching between capped and exposed turret styles?
Capped turrets protect against accidental adjustments and are quieter, while exposed tactical turrets provide rapid, repeatable adjustments with zero stop and easy-to-read markings for precision ranges.
What makes this scope balanced for long field use?
Weighing around 678 g and measuring ~371 mm, it remains compact and manageable, reducing fatigue during extended shooting or hunting sessions.
How should shooters interpret turret clicks in real-world distances?
Each 0.25 MOA click moves the point of impact approximately 0.25 inch at 100 yds, allowing accurate corrections for wind and elevation at long range.
How does the exit pupil change across magnification, and why does it matter?
Exit pupil ranges from approximately 7.6 mm at 4× to 2.1 mm at 24×, affecting brightness and eye comfort; larger pupils at low magnification aid low-light visibility.
How does the reticle calibration at 12× impact practical use?
The ballistic markers correspond to 12× magnification, serving as a reference for holdovers, so shooters can quickly engage targets without adjusting turrets unnecessarily.
How does the Titanium HD compare in optical clarity with entry-level scopes?
Premium HD glass and multi-layer coatings provide superior contrast, edge-to-edge sharpness, and color fidelity, significantly outperforming budget optics at high magnification.
