Holosun is releasing the new AEMS Core, a smaller-sized optic that provides all the features of the Holosun Core at a competitive price point.

The AEMS Core is constructed from a durable cast aluminum housing that offers excellent protection and durability. AEMS Core features a 2-MOA dot with 12 brightness settings, 10 daylight and 2 night settings that are compatible with night-vision gear. The settings are controlled by two buttons located on the left side of the housing, with a CR2023 battery compartment that opens on the other side of the optic. The battery provides up to 50,000 hours of continuous operation at a mid-range setting. The AEMS also has a Shake Awake feature that puts the AEMS Core to sleep in order to preserve battery life, yet reactivates the reticle with the slightest movement of the optic.

At 2.13 inches long, 1.42 inches wide and 1.69 inches tall, the AEMS Core is 11-percent shorter than most optics in the 20 mm class. The optics weighs 3.9 ounces without a mount, making it a versatile option for nearly any rifle, shotgun, or SBR setup. It comes with a 1/3 co-witness mount to perform across a variety of different guns. In addition to this, Holosun provides a lifetime warranty on the AEMS Core.

Tech Wisdom: 45 ACP Revolver Conversion Cylinders

I am hopelessly enamored with .45-caliber, single-action revolvers, especially those that accommodate the .45 ACP cartridge for everyday use, plinking and informal target shooting. My hands appreciate the reduced recoil of the .45 ACP as opposed to the heavier loads I use in the .45 Colt cartridge for hunting as well.
