Preview: Holosun HM3XT Magnifier

Holosun unveiled a few new additions to its line of optics for 2020, like the HE509T-RD small titanium-housed reflex sight. These new products are noteworthy in their construction and capability. Another addition to fit the trend is a magnifier to accompany its line of reflex sights.

The new Holosun HM3XT is a 3X flippable magnifier that adds versatility to a rifle or carbine with a mounted RDS. It is relatively similar to Holosun's previous HM3X flippable magnifier, but with some noteworthy differences. The most notable is the construction of the housing, which is made of titanium, like the company's 509 and 512 RDS offerings.

The titanium housing is light yet durable, keeping the weight down while being able to withstand abuse. The HM3XT also has a IP67 waterproof rating, which means it can spend half an hour at a depth of a meter without losing watertight integrity. Another difference from the previous HM3X is that the length of the magnifier itself is shorter, making it less bulky when mounted.

Windage and elevation adjustment tabs are present on the magnifier to allow for fine tuning the sight picture with the RDS of choice. The eye relief is at 2.75”, allowing it to be set forward to accommodate back up iron sights and to reduce strain on the user’s eye.

The mounting system is a simple, quick-detachable lever system that allows it to be locked on or removed from any Picatinny rail without much effort while retaining zeroed settings. The mount features a spacer to allow the height of the magnifier to be set at either absolute or lower 1/3 co-witness. The magnifier is easily flipped to the side for stowage and back in place for use, depending on the situation.

In the box with the magnifier comes the QD mount, a T10 L key and the user manual. The suggested retail price for the Holosun HM3XT 3X magnifier is $388. For more information, visit holosun.com.
