REDWIN CORSAC PRISM 1×18 RMP1 Prismatic Sight – Precise Optics for Demanding Shooters

The REDWIN CORSAC PRISM 1×18 RMP1 is a modern 1x prismatic sight, designed for users of carbines and shotguns equipped with a Picatinny rail. Thanks to its prismatic system and etched reticle, it is especially recommended for people with astigmatism, for whom classic red dot sights often do not provide a sufficiently sharp image of the dot.

Its compact design, high resistance to weather conditions, and the ability to choose the mounting height make the CORSAC PRISM perfect for sport, dynamic, and recreational shooting.

Ideal Choice for People with Astigmatism

One of the biggest advantages of prismatic sights is the use of an etched reticle, which remains clear even when the illumination is turned off.

Unlike classic red dot sights, where the dot may appear blurry or deformed, the prismatic system provides a much clearer image. This makes the REDWIN CORSAC PRISM an excellent choice for people with astigmatism and users who expect maximum reticle sharpness.

Clear Image and Fast Target Acquisition

The optical system uses Fully Multi Coated (FMC) – full multi-layer anti-reflective coatings that:

• increase light transmission,
• improve contrast,
• reduce reflections,
• provide a bright and clear image.

1x magnification allows for aiming with both eyes open, which translates into faster target acquisition and better situational awareness.

LED Illuminated Reticle

The sight is equipped with an LED illuminated reticle, whose brightness can be adjusted to lighting conditions.

The user has at their disposal:

• 8 daytime brightness levels,
• 2 night vision compatible (NV) levels.

This allows the sight to perform well in full sunlight as well as in low-light conditions.

Robust Construction for Intensive Use

The body is made of durable aluminum, which ensures high mechanical resistance while maintaining a low weight.

The CORSAC PRISM model has been:

• tested on .223 Remington, .308 Winchester, .300 Blackout calibers and M193 ammunition,
• protected in accordance with the IPX67 standard, which means resistance to dust, rain, and short-term submersion,
• adapted for intensive use on sport carbines and shotguns.

Two Mounts Included

The manufacturer includes two mounts compatible with the T1/T2 system, allowing for the selection of the appropriate height:

• high mount – 1.6 inches
• low mount – 1.1 inches

This allows for easy adjustment of the sight's height to the platform and preferred shooting position.
