SX3 is a version of semi-automatic shotgun, which reached a lot of world records; the last of them gave SX3 title of The fastest shotgun
in the world, 12 shots within 1.4 second! Finishing of Ultra Tough Coat type indicates ultra-durable finish. The unique coating of new SX3 in grey metallic color constitutes finishing of great endurance, which in addition to its nice appearance, provides extraordinary resistance to corrosion, even in extreme conditions. SX3 was designed in an innovative way in order to create the most reliable, 
fastest-shooting and with the smallest recoil semi-automatic shotgun. Very simple principle of operation uses a gas piston with inner Active Valve, which is automatically controlled to ensure possibility of applying the wide range of different loads.
fastest-shooting and with the smallest recoil semi-automatic shotgun. Very simple principle of operation uses a gas piston with inner Active Valve, which is automatically controlled to ensure possibility of applying the wide range of different loads.Barrels using the Back Bored technology provide the best use of ammunition parameters, including among others:
1 - Increased speed and penetration.
The use of Back Bored reduces friction of shots at the sides of barrel. Instead to overcome frictional resistance, the greater amount of energy released by gasses produced during combustion of gunpowder is used to move the shot, so that increases the speed of load. Shot retains its ballistic parameters.
2 - Better parameters of cover. Ballistic characteristics undergo improvement and thanks to that you get an extraordinary uniformity of coverage, a lot more of shot effectively hits the target
3 - Reduced perceptible force of recoil indicates greater comfortable of shooting. The shot load in barrel with internal profile moves with greater easiness, thanks to that the shooter experiences less recoil, which increases comfort.
Our project has extended magazine, so this shotgun can be loaded with 12 cartridges and fibre-optic sights facilitate quick guidance on target. The barrel is connected with the magazine through assembly of Picatinny rail, on which you can mount the flashlight or e.g. camera. However, the inspiration of this weapon project wasn't Hollywood, but a title of "The fastest shotgun in the world" and super light operation, which gives the possibility of training even by very small persons.
