The new SLIM series from Nocpix provides the best value and features in a compact optic. Focused on versatility and ease of use, SLIM models can be used as either a handheld monocular or a weapon sight. With the included proprietary quick-detach mounting system a hunter can quickly scan and then re-attach the optic to the rifle while maintaining zero. A magnesium alloy body and quiet, soft-touch buttons provide excellent ergonomics in both handheld and weapon-mounted configurations. The included IRB-2 batteries (flay-top 18650 style cell) are easy to swapletting you stay out longer with the ability to charge through the optic using a magnetic cable. Generous eye relief and a 1024x768 AMOLED display provide a comfortable and highly detailed viewing and hunting experience.
