Vortex Impact 4000 Cap With Integrated ARD Introducing our new Vortex Impact 4000 Cap With Integrated ARD for the Vortex Impact 4000 Laser Range Finder. The Impact front objective lens uses similar coatings to standard objective lens coatings on modern rifle scopes that can be easily damaged or hard to keep clean properly. The large objective lens will also attract a lot of sunlight and the ARD honeycomb design will help keep that glare from reflecting off the rangefinder. Our cap will also help to protect the lens from damage if accidentally dropped or hit. This Cap will help keep your glass clean and free of debris and water while trekking through the woods or waiting for your squad to be called up to compete. This cap was designed with a high-tech 3D scan of the Impact for a perfect snug fit. The perfect fit is also complimented by tool free snap on installation which makes it easy to install and remove in the field or on the bench for maintenance. Field testing has shown us that the honeycomb pattern in front of the lens has very little affect (if any at all) on the units ability to range accurately. At 587 yards we were getting results /- 1 yard over the course of many tests which very well could just be the tolerance accuracy of the unit showing. Testing at 960 yards showed us the same results.

After each layer, powder is distributed on top of the bed and the process repeats until the part is complete. The method of printing allows for fine details and part geometries that are difficult to accomplish via other manufacturing processes. After each print job is completed parts are allowed to cool off to prevent warping. After parts have cooled, excess powered is removed via and automated blasting machine. After the excess powder is removed the parts receive in an initial polishing via an automated blasting machine. Next parts are dyed black with a custom made dye made for us by RIT. After parts have dried, they are polished one additional time to improve surface finish and color consistency.
