Us Optics Mcrs Review


Investing in a worthy optical sight does not have to bloat your bank account balance as markets are now filled with cheaper and highly effective red dots that come equipped with durable batteries. But then again it depends on what you want to use the red sight for; sights acquired for duty or job applications are normally highly effective with numerous customizable features that help increase operability, one such sight is the US Optics MCRS.

Lost dots under bright lights or the over-bright dots in low light, and short battery life, are some of the problems that most sight owners are likely to experience while using the optical sights but which are not welcome. What’s more is that not everyone prefers to use the red dot, because they are color blind and would rather get the green dot.

The US Optics Mcrs is equipped with most of the relevant features, such as a clear glass, the sight sports a low profile, a feature that makes it adaptable to most weapons, and is thus, effective and fulfilling in so many levels, check below.

Us Optics Mcrs Review and Breakdown

The Mcrs optical sight is among the high-end sights retailing at a high price of $550, the units offer the 4MOA red dot, which means that @ 100 yards the dot will cover approximately 4 inches. The 4MOA dot is, therefore, a good option for shooters who want to cover longer distances, and with maintained precision, the Mcrs remains highly effective, for shooters who prefer taking the close up shots,

Another feature that stands out in the Mcsr is the auto-brightness adjustment option, which will orient the sight with regards to the relevant surrounding thus offer you the relevant dot intensity. The sight doesn’t turn off, meaning that your battery will have to take the beating and might not be long-lasting as it is supposed to.

The sight is compact, and portable, sits low when mounted, which then attracts some serious disadvantages, so whenever you want to change the sights battery, you will have to dislodge the whole unit from the weapon, which could eat up a good chunk of your time. The battery sits under the sight with no protection covering unless when it is mounted.

The incorporated glass is wide enough and very clear, and on the outside, there is minimal shifting. No matter the number of shots you take, the sight effectively holds zero. Out of the box, the Mcrs comes with an Allen wrench used to dislodge and install the sight from the weapon. And when using the sight from concealment to draw, users will experience zero lag because the brightness auto adjustment feature is pretty effective and you will be provided with a red dot the moment you aim your weapon.

Retailing at a high price of about $550, the US optics Mcrs features a matte black outer finish, which not only makes the sight attractive but enables it to complement the weapon with which they are being used on.

Brightness settings

The brightness adjustment settings in this sight are automatic with the lowest setting provided for the low light environments while the highest is visible against the sky in bright daylight.
