Sightmark Core TX 1-4x24

• 1-4x LPVO range: True low magnification at 1x supports fast target acquisition at short distance, while 4x gives enough reach and detail for deliberate shots at medium range.
• Second focal plane illuminated reticle: The SFP layout keeps the reticle visually consistent through the zoom range, and the illuminated center helps the aiming point stand out in dim light or against dark backgrounds.
• Fully multi-coated 24 mm optics: Coated lenses improve contrast and light transmission, helping the image stay clear and usable in changing field conditions.
• Tactical double-turn turrets: 1/2 MOA clicks and generous elevation and windage adjustment give the shooter clear, repeatable corrections for zeroing and practical hold refinement.
• 30 mm nitrogen-filled tube: The single-piece tube, waterproof, fogproof and shockproof construction supports reliable use on working rifles in rain, temperature changes and recoil.

About the Sightmark Core TX Series

The Sightmark Core TX series sits within the broader Core riflescope family and is aimed at shooters who need practical optics for hunting and tactical shooting without moving into more specialized long-range models. The series includes both fixed-power and variable-power designs, giving it a broad role across close- to medium-range applications. Across the line, Sightmark uses second focal plane reticles, a format many shooters prefer for its familiar sight picture and consistent reticle appearance as magnification changes.

Core TX riflescopes are built around a straightforward mechanical design with aircraft-grade aluminum construction, fully multi-coated optics and protection against water, fog and shock. That makes the series a sensible fit for rifles that see regular field use rather than occasional range time. Reticle options in the family include AR-223 BDC and dual-caliber BDC patterns for .223 and .308 platforms, showing that the series is intended for practical shooting tasks where quick aiming references matter. In Sightmark’s lineup, Core TX models bridge ease of use and field durability, making them suitable for newer shooters as well as experienced users who want a compact, uncomplicated optic.

About the Sightmark Core TX 1-4x24

The Sightmark Core TX 1-4x24 is a compact LPVO riflescope built for rifles used from close quarters out to medium distance. Its 1-4x magnification range makes it especially useful on carbines and general-purpose hunting or tactical rifles, where the shooter may need a wide field of view at low power and more target definition a moment later. At 1x, the scope remains quick to pick up, while 4x gives enough magnification for more careful shot placement. The 24 mm objective lens keeps the optic trim and easy to mount without adding unnecessary bulk.

This model uses a second focal plane illuminated reticle, so the reticle size stays visually constant through the zoom range. In practice, that gives a familiar sight picture and helps the aiming point remain easy to read at both low and high magnification. The red and blue illumination adds contrast when the target or background is hard to separate in poor light. Tactical turrets with 1/2 MOA clicks provide clear adjustment feedback, and the double-turn layout offers substantial travel for zeroing and correction. A 30 mm tube, nitrogen filling and waterproof, fogproof, shockproof construction support dependable use in rough weather and repeated recoil. With 94.00 mm to 101.60 mm eye relief and a broad field of view from 32.00 m/100m to 8.00 m/100m, the scope balances speed, control and practical versatility well.
