TheHatsan 90 STG gen II 5.5mm is a powerful spring-loaded carbine featuring an ergonomic polymer stock, adjustable Quattro trigger mechanism and SAS recoil reduction system.
Ergonomic buttstock
The carbine's stock is made of durable polymer, which is resistant to mechanical damage, weather conditions and moisture. Maintenance and cleaning of the plastic bed is limited only to keeping it generally clean and occasional use of silicone oil.
TheMonte Carlo-type symmetrical buttstock allows right- and left-handed shooters to comfortably assemble for shooting and use higher-mounted optics.
Post-shot recoil is effectively absorbed thanks to a soft rubber foot, also providing a stable point of support.
Fine mottling was applied to the pistol grip and the front of the bed, which improves hand grip and enhances the aesthetic qualities of the carbine.
Due to its size and weight, the carbine is intended for adult and experienced users.
Classic loading
Thespring is tensioned by the classic "barrel break", a method most often used in spring-loaded windcheaters due to its convenient and simple operation. The Hatsan 90 STG genII 5.5 mm shoots diabolo shot in 5.5 mm caliber, loaded directly into the barrel.
The polymer dummy suppressor with non-slip milling significantly eases barrel breakage and spring tension, most noticeable during long shooting. The spring has an Anti Bear-Trap safety, which protects it from uncontrolled release during tensioning.
Precision and long range
The 450mm long threaded barrel is responsible for the accuracy and repeatability of the shots, thanks to which we can achieve repeatable focus after just a short training session.
The fired shotgun reaches a high initial velocity of about 245 m/s (~16 J), thanks to which we can also shoot accurately from the carbine at longer distances.
The enlarged compression chamber allows us to carry out self-tuning, thanks to which we can increase the initial velocity of the shotgun.
SAS recoil reduction system
The carbine uses a patented SAS (Shock Absorber System) mechanism, which absorbs a significant part of the energy that accompanies the firing of the windgun. The SAS system increases the comfort of use, extends the life of the internal mechanisms and protects the optics from shocks.
Adjustable Quattro Trigger mechanism
One of the most important parts of the weapon affecting its accuracy is, of course, the trigger mechanism.
In the Hatsan 90 STG genII 5.5mm model, the manufacturer used a two-stage Quattro Trigger match trigger, allowing the shooter to individually adjust the length of the initial travel and resistance.
The wide range of adjustment increases control over the shot, affects accuracy and shooting comfort.
Automatic safety
In shooting, the most important thing is safety, so when the spring is stretched ("breaking the barrel"), the fuse is automatically activated, which prevents the firing of an uncontrolled shot.
Before firing, you should always turn off the safety, which is conveniently located in the rear of the piston chamber. This affects the extremely easy unlocking of the carbine, which can be done even without interfering with the aiming process.
Fiber-optic sighting instruments
The carbine has been equipped with good quality fiber-optic targeting instruments, i.e. a fixed bow tie and a vertically and horizontally adjustable sights.
The fiber-optic rods with contrasting (green-red) colors, significantly speed up the alignment of the bow tie and the pincer, and thanks to high light absorption, also allow shooting in low or residual light, for example, after dark.
If you want to try your hand at shooting at longer distances, you can also mount an optical sight of your choice on the 11mm rail. The rail has holes for a stop pin, eliminating the "loss of zero" problem.
