It comes in 30mm and 34mm tube variants – either 4-16×44 or 6-24×50. There’s a choice of illuminated reticles too – either the precision rifle reticle, or a half mil-dot reticle.
“What really sets this scope apart is the distance you can adjust the parallax down to. It dials all the way down to 10 yards,” says Ryan. “That makes it ideal for a rimfire or airgun, or people who are using digital rear add-on night vision.”
So why use a First Focal Plane scope? “With FFP, when you adjust the magnification you zoom in or out of the reticle as well as the image – the two stay in proportion. So your hold points remain the same regardless of magnification,” Ryan explains. “That makes the scope very easy to use. If you want to raise your aim by half a mil, you dial in 0.5 on the turret and the job’s done, whatever magnification you’re using.”
The turrets are calibrated at 1/10th mil clicks, and you simply lift them up to adjust. “Nice positive clicks too,” comments Ryan. There are other useful features too, such as the reference point on the magnification ring, which is easy to feel with thumb or finger.
There are many more great scopes in the Nikko Stirling Diamond range, but these two are well worth a look for a rimfire or airgun. Prices are £386.99 for the 4-16×44, and £450.99 for the 6-24×50.
