The double roller muzzle for spearguns is entirely made of nylon reinforced with fiberglass and is characterized by several specifications:

• It is equipped with a stopper that prevents the elastics from coming out after firing, enhancing safety and tool management.
• The overlapping system is made possible by two different pulley sizes: a front pulley with a diameter of 36 mm and a rear pulley of 28 mm. This system provides smoother and more efficient operation.
• The muzzle can accommodate elastics up to 15 mm wide, providing adequate launching power for its purpose.
• It is designed to be suitable for tubes with diameters ranging from 26 to 26.7 mm, offering versatility for use with different types of spearguns.
