It's optics this time for Mister Moro to review in this Hyperdouraku review... "Nobel Arms' latest dot sight SURE HIT ARP2 is characterized by its square shape. Although it is a tube type, its angular square form also suits PDWs such as MP7 and P90, and submachine guns such as MPX and modernized MP5. A flip-up lens cap, high mount/low mount, and RMR conversion plate are also included. It can be loaded with anything from long objects to handguns (separately sold plate required).

It has 10 brightness levels, a slightly bluish lens with little distortion, and parallax is minimal enough to cause no problems at airgun ranges. Equipped with a 5-minute motion activation function, auto-off, auto-return, and 8-hour auto power-off function.

The battery is one CR2032. The brightness adjustment button on the left side is also easy to operate.

The weight of the main unit is 70g, so it will be heavier to operate when mounted on a gas blowback, but it feels like the recoil has increased accordingly."
