Core Specifications

Comparison Shield Rmsc Vs Holosun 507k

1. Durability

Shield RMSC and Holosun 507k x2 sights are designed to survive severe recoil and hard use. Waterproof, shock-resistant, and fog proof are all features of the Shield RMSC’s durable aluminum housing. Like the Holosun 507K X2, the Shield RMSC is made of a sturdy aluminum chassis and is waterproof, shock-resistant, and fog-proof.

The Holosun 507K X2 has, however, been shown in tests to be more resistant to recoil than the Shield RMSC. The Holosun 507K X2 has been verified to withstand 1,000 Gs of recoil, but the Shield RMSC is only rated for 500 Gs. 

Ultimately, both of these sights are built to last, however, if you need a sight that can resist the most extreme amounts of recoil, the Holosun 507K X2 could be your best option.

Winner: Holosun 507k x2

2. Glass Clarity

The Shield Reflex Mini Sight Compact (RMSC) and the Holosun 507K X2 are both built with strong glass and multi-coated lenses to deliver a clean and crisp image.

The completely multi-coated lens on the Shield RMSC is made to deliver an undistorted, clear image. In order to preserve clarity and guard against damage from dust and other external variables, the glass is also scratch-resistant.

Similar to this, the Holosun 507K X2’s lens has a multi-layer coating to produce a sharp image. The lens is also parallax-free, so the reticle maintains its center regardless of where the shooter’s eye is located.

Nevertheless, both sights are made with premium glass and multi-coated lenses that provide great clarity and brightness. Given that both sights are regarded as top-tier choices, it is impossible to choose one as being more glass-clear than the other.

Winner: Draw

3. Battery

The Holosun 507K X2 uses a CR1632 cell, which is a typical and generally accessible type of battery, but the Shield Reflex Mini Sight Compact (RMSC) requires a CR2032 battery.

The Shield RMSC includes an automated shut-off after eight hours of inactivity, which helps preserve battery life, and has a battery life of roughly 4,000 hours on a medium setting. Without taking the sight off the gun, the battery may be readily replaced as the battery compartment is situated at the top of the sight.

Likewise, the Holosun 507K X2 has a battery life of about 50,000 hours on a high setting and Shake Awake functionality, which turns the sight on when motion is sensed and turns it off after a time without use.

The Holosun 507K X2 has a much longer battery life than the Shield RMSC, however, both sights employ a comparable type of battery and have a long battery life in general.

Winner: Holosun 507k x2

4. Reticle

The standard reticle for the Shield RMSC is a 4 MOA dot reticle, which is appropriate for close- to medium-range shooting. For shooters who favor a larger aiming point, Shield also provides an 8 MOA dot reticle option.

As opposed to the Shield RMSC’s 4 MOA dot, the Holosun 507K X2’s standard reticle is a 2 MOA dot, which is slightly smaller and more accurate. A circle-dot reticle option, which combines a 2 MOA dot with a 32 MOA circle for quicker target acquisition, is also available on the Holosun 507K X2.

Winner: Holosun 507k x2

Correspondingly, the Holosun 507K X2 has an auto light output setting that adjusts to the illumination conditions, as well as a mechanical adjustment option with 12 luminance settings. The manual settings allow the shooter to fine-tune the illumination to their liking, with the highest settings appropriate for bright daylight conditions and the lowest settings appropriate for poor lighting conditions.
