Full description


This optic is a real steel shooting sight, meaning that it is of the highest quality and durability, and when compared side by side to an Airsoft replica sight it absolutely blows them out of the water. The sight is constructed from lightweight aluminium and features special coatings and a range of other technologies to protect the optic during use. Due to the quality and strength of the sight it comes with Vortex's transferable unlimited lifetime warranty, meaning they will replace the sight should it no longer function for any reason, if the optic becomes damaged just send it back to Vortex and they'll replace it. This warranty is transferable and lasts forever, so this could be the only sight you'll ever need to buy, and they'll even cover the warranty if the optic is shot out due to a stray BB.

The sight is compatible with both Burris Fast Fire, Doctor Mounts and Airsoft Pistol Sight mounts which are to spec, and comes provided with an adaptor which allows you to place the sight on 20mm RIS / RAS rails as well. Due to the wide range of mounting options this sight can be affixed to both pistols and main rifles, allowing you to use the same optic across multiple different weapon platforms.

The sight's lens provides no magnification, but instead projects a red dot into the field of view of the user to allow for quick target acquisition to make your first shot faster and easier to take. The lens itself is fully multi-coated to reduce reflections and light transmission, and is finished with a premium ArmorTek lens coating which is designed to reduce scratching as well as oil and moisture build up on the optics lens to ensure high performance at all times. The lens is parallax free and has unlimited eye relief meaning that no matter where you shoulder the weapon, or mount the optic, you'll still have the same clear sight picture from any angle.

The optic is also fully adjustable, in addition to the brightness settings the windage and elevation can also be finely tuned, with 130 MOA max elevation adjustment, and 100 degrees of MOA windage adjustment, the optic can be adjusted to be used on a wide variety of rifles, pistols and more for a wide range of distances.

The optic's dot is projected by an inbuilt laser, which can be adjusted to up to 10 levels of brightness depending on the lighting conditions you are shooting in. The brightness can be turned down for indoor and CQB shooting to prevent glare, and can be turned up to the max when shooting outdoors in high light conditions. The sight is also highly battery efficient, powered by a single CR 1632 battery and provides up to 150 hours run time at its highest setting, and an astonishing 30,000 hours run time at its lowest brightness setting. To prevent wasted battery the sight also shuts down automatically after 14 hours of use, a life saver if you forget to turn the optic off before you pack up your kit.

The optics dot is available in two different sizes, a 3 MOA variant, and a 6 MOA variant. MOA stands for Minutes Of Angle which is how big the dot will look at 100 yards, 3 covering 3 minutes of angle at 100yards, and 6 minutes of angle at 100 yards. The smaller dot is more suited for outdoors and ranged shooting, with the 6 MOA version designed for more closer range shooting up to 100 yards.

The Venom sight is fully shockproof and water proof, making it highly durable and tough enough to withstand the rigours of any Airsoft game. The sight has been designed to be water proof to protect the internal workings of the sight from dust, debris and moisture to ensure it will keep working no matter the weather conditions. The sight been designed to be shock proof to allow it to be fitted to real steel rifles and pistols to ensure they do not lose their zero when shot, this means that they are way more than capable of handling Airsoft Gas Blowback and Electric Recoil weapons without losing any zero when they are shot, a common problem for cheaper Airsoft replica sights.

This sight is perfect for both real steel shooters with real weapons, with high quality you can trust and a super clear optic, and for Airsoft players as well who appreciate quality, want a sight which they'll never have to replace and will work perfectly no matter what it is attached to. This optic may be the last micro red dot you will ever have to buy.
