A New Closed Optic Ready to Work, the C&H DUTY

Richmond Hill, Georgia (January 17, 2022) – Fully enclosed optics have long been the benchmark for durability. Having emitters protected from dirt and debris makes sense in harsh environments. Also, the optical glass is well protected from unnecessary scratches and damage. While not always necessary, users often prefer this added peace of mind in their optics when used in high failure areas due to physical damage or abrasive elements. What’s even more difficult is finding an optic that meets all of these needs and is small enough to mount on a pistol. C&H Serves the precision consumers need in DUTY pistol optics.

The DUTY is an enclosed side-clamp mount optic that keeps dust, rain, twigs, grass, or other foreign objects out of the optic. Manufactured from a one-piece CNC aircraft aluminum housing, it comes crash rated to +P and +P+ and is water resistant. Additionally, the IPX7 rating allows 1 meter submersion for up to 30 minutes. A CR 2023 lithium battery is attached to power an optic with a lifespan of 50,000 hours. A shake and automatic shutdown after 5 minutes are standard to preserve battery life.

DUTY comes with two reticle color options; Red or green. Additionally, there is an option for a multiple reticle system. While a 3 MOA dot comes standard on all models, the multi-reticle system comes with a 48 MOA circle that can be used independently or in conjunction with the 3 MOA dot. These reticles have ten brightness settings, two of which are night vision compatible.

No one can predict the exact environment they will find themselves in when they need to defend themselves. An optic that can handle a wide range of environmental hazards and operate at maximum efficiency takes the guesswork out of choosing optics. DUTY by C&H Precision provides the best protection for a pistol optic; it is at home both in the sand and in the swamp.
