CNC milled engravings are made by using computer-aided design CAD software to create a digital model of the engraving, which is then translated into a set of instructions that a CNC machine follows to precisely mill the design into the material. The process involves using a cutting tool, such as a rotating end mill, to remove material from the surface of the material, creating the desired pattern or design.. Veteran crafted in the USA.

Ade Advanced Optics RD3-006B Green Dot Sight for Handgun - Not Red
This green dot sight comes equipped with a Picatinny mounting base and is also compatible with various handgun mounting plates that replace the rear sight dovetail. It's designed to fit the Doctor Footprint PlateSlide seamlessly.. The onoff switch for this sight is conveniently positioned at the front, making it much easier to press compared to red dots with side-mounted switches. It features a 3 MOA dot size and offers 5 illumination settings. The sight is fully adjustable for windage and elevation and can be locked into place. With unlimited eye relief and various illumination settings, it is powered by an included lithium CR2032 battery.. Since its initial release in 2014, we've implemented numerous improvements to enhance its durability, ensuring it can withstand recoil while also improving its ability to hold zero. The front switch, battery housing, and hardware have all been recently updated, reflecting our commitment to continuous enhancement. This product is proudly designed in Oregon.. Although it's feasible to install the optic on a handgun without the assistance of a gunsmith, we highly recommend seeking the expertise of a professional for the installation process. It's essential to note that unprofessional installations, such as improper torque application, can lead to issues like loose screws, an inability to hold zero, damage to the firearm or optic, and even pose a risk of personal injury.. If you're not seeing a perfect round dot but instead observe a splashed dot, half-moon shape, multi-dot, or starburst, there's a high probability 99 that you might have astigmatism without being aware of it. What you perceive is likely a small reflection of the LED light on the lens. A quick and simple way to confirm this is by using your cellphone to take a photo of the dot. If the photo shows a circular dot, you've essentially diagnosed yourself with astigmatism..
