Adelaide-based laser products manufacturer Laserex Technologies has announced the release of its new GLS-520 Green Laser Sight. Australian made and manufactured to withstand the harsh conditions found in the outback, the GLS-520 utilises advanced laser diode technology and high-quality precision glass optics, making the unit ideal for both professional and recreational shooters.
Green laser sights are around five times brighter than red laser sights, which makes them far easier to see as the colour green is more sensitive to the human eye than the colour red. Hence, green sights have a distinct advantage over red laser sights in terms of visibility. Previous green laser sights used green diode pumped solid state (DPSS) laser technology. This resulted in a limited operating temperature range, which meant that these products would not work in cold and hot temperatures. Another disadvantage of green DPSS lasers was their unstable output power.
The GLS-520 overcomes the shortcomings of DPSS lasers and operates in a wide temperature range, from -15 to 60C. The unit comes with a 520nm green laser diode that eliminates the need for warm-up times associated with DPSS lasers. The dot size of DPSS lasers is large due to the larger beam divergence angles produced and hence DPSS lasers are ineffectual for shooting. The GLS-520 has a small spot that is less than 35mm at 100mm with a circular beam shape.
One of the advantages of using the GLS-520 is the increase in accuracy. A green laser sight greatly increases the likelihood of a direct hit, first time. When sighted to your firearm, the bullet will strike where the laser spot is on your target. Being visible to the shooter, either when attached on the rifle or viewing it through a scope, makes for an accurate first shot - essential when managing feral pest species such as rabbits, pigs, foxes and goats.
There are some laser sights on the market that do not meet Australian Standards in terms of output power and safety and these can be dangerous to users if not operated correctly. However, the GLS-520 is Class 2 and fully compliant with Australian Laser Safety Standards AS/NZS 2211.
The GLS-520 weighs 300g and is made of aluminium alloy with a black matte finish. It is also shock-resistant and withstands heavy recoil, holding its zero even on heavy-recoiling centrefire firearms. The GLS-520 kit comes supplied with a 1" scope mount and 5/8" Weaver rail and has a 1km range with a scope. Also supplied is a rechargeable CR123A battery, which provides four hours of continuous use, along with a switch lead and an Allen Key for attaching the mounts. It is also possible to operate the GLS-520 with a constant on/off switch. Two external adjustment knobs allow for quick and easy X-Y adjustment of the laser beam, making the GLS-520 ideal for dawn, dusk and night-time use.
The GLS-520 comes with clear and concise instructions as to how to zero the laser sight to your firearm. Priced at $385 inc GST, with a one-year Australia-wide manufacturer’s warranty, the GLS-520 can be ordered through Laserex’s secure online shop.
