The Theta Optics Luneta series of riflescopes are basic but effective non-illuminated scopes with the highly functional "Mildot" reticle, providing index marks on both the horizontal and vertical planes of the scope's crosshair to allow on the fly estimations of range and windage, as well as allowing moving targets to be engaged more easily. The scope is adjustable between 3x and 9x magnification, covering the entire spectrum of usefulness for Airsoft skirmishes, and comes with 25mm/1-inch scope rings for 20mm Picatinny rail.

Full description


The Luneta 3-9x40mm riflescope is a great option for a skirmisher who intends to try their hand at sniping but doesn't want to spend huge money on a role they may not stick with. Supplied with 25mm scope mounts for 20mm Picatinny rails, the Luneta 3-9x40 comes with everything you need, bar the gun, to start harassing the enemy at long range.

The objective lens of the scope is 40mm in diameter, allowing plenty of light in and providing a large field of view, ensuring you can see as much as possible around the target you have set your sights on. The tube of the scope is 25mm/1-inch in diameter, granting you loads of flexibility in mounting options, though the scope includes basic scope mount rings so you are ready to go out of the box.

The adjustment turrets have threaded protective caps, removing these reveals the adjustment dials, which can be adjusted without tools or using a flat head screwdriver if you don't want to get your hands/scope dirty. The protective caps help the scope retain its zero even if you bump or knock the sight and aid in protecting the scope's delicate internals. The turret on the top of the scope provides elevation adjustment whilst the turret on the right side adjusts the windage.

The magnification adjustment ring can be found just ahead of the "eye-bell" of the scope, and can be rotated around the circumference of the scope to select your magnification setting; from 3 all the way out to 9x magnification! This provides the perfect amount of adjustment for Airsoft purposes. 3x Magnification is perfect for engaging at any range and having the functionality to zoom in all the way to 9x allows you to spot the opposing team long before you have to engage them.

The Luneta 3-9x40mm scope also comes supplied with a lens protector, which prevents the eye lens and objective lens from being scratched. These are probably not Airsoft proof, though they may survive a single shot we still recommend a proper Airsoft rated lens protector to avoid damage from incoming fire.
