Focus Lever for DNT / Arken 3-12x and 5-20x Digital Night Vision Scope
The lever fits securely into the grooves of the focus barrel, ensuring no looseness and allowing easy positioning for both near and distant targets. Focusing on nearby objects places the lever at the 12 o'clock position, while a simple 60-degree clockwise movement brings it to 2 o'clock for distant focus. Designed with precision, the lever fits in 30-degree increments to accommodate slight variations in factory assembly, ensuring optimal positioning every time.
Crafted from high-quality, durable matte-black plastic using 3D printing technology, the lever is built to last. The ribbed surface ensures a firm grip, even in wet conditions, and the stainless-steel screw and embedded nut prevent rusting. Installation is quick and simple, with no need to remove the lens cap, and a No. 1 Philips screwdriver is required for tightening.
