Optisan Optics CP 4-16x40 F1 FFP Non Illuminated F1MOA16 Side Focus 30mm Rifle Scope
The Optisan Optics CP 4‑16x40 F1 FFP Non‑Illuminated F1MOA16 Side Focus 30 mm Rifle Scope is designed for shooters who demand precision, versatility, and durability in one compact optic, offering a smooth 4–16× magnification range and a 40 mm objective lens that delivers bright, sharp images from close to mid‑range targets. Its First Focal Plane (FFP) F1MOA16 reticle scales with magnification, ensuring that holdovers and corrections remain accurate at any power. With 0.25 MOA per click turrets and a side focus parallax adjustment, you can fine‑tune your aim and maintain a crisp, aligned target image at varying distances. Built on a rugged 30 mm main tube with fully multi‑coated optics, this scope stands up to field use while remaining lightweight and easy to handle, making it ideal for hunting, tactical shooting, or precision target work.

The highly anticipated Optisan CP first focal plane riflescopes have finally arrived. This scope is available in both MRAD-based reticles and MOA-based reticles. These come with matching click values to it make sit nice and easy whilst out in the field to make your adjustments and holdovers.
The main reason the first focal plane reticles were introduced to the CP'S was due to the fact that the first focal plane reticles are always consistent no matter what magnification you are on. So with this being an air rifle focus rifle scope, predominantly used by HFT and vermin control, having the ability to call holdoffs using your reticle on every magnification is incredibly useful. This was the feedback received by Optisan and they listened to bring you the Optisan CP 4-16x40.
Much like its second focal plane brother, the Optisan CP 4-16x40 FFP MOA measures only 268mm in length and weighs only 530 grams. It features a 30mm main tube and one-piece construction made from aircraft-grade aluminium. If you are buying the first focal plane MRAD riflescope you are going to get a 0.1 MRAD click, and if you are buying the first focal plane MOA, you are going to get a ¼ MOA click. The turrets on these are low profile and under caps.
Both the MRAD and the MOA versions of the Optisan CP 4-16x40 F1 come with a non-illuminated reticle and feature a hash-mark reticle which will provide the shooter with more than enough holdover points to accurately call wind calls without having to dial in the turrets, making it a perfect choice for Air Rifle Shooters.
To follow on, the Optisan CP 4-16X40 has parallax adjustments from 10 yards out to infinity and features fully multi-coated lenses which are consistent throughout the CP range of riflescopes which shooters are incredibly happy with.
