Cylinder set (Bore-Up) for AK47/AK47S (NEW) - SHS

Cylinder Set (Bore-Up) for AK47/AK47S (NEW) – SHS Cylinder Set (Bore-Up) for AK47/AK47S (NEW) – SHS is a complete air system designed to increase the performance of airsoft guns, especially when using longer barrels. Bore-Up parts have an enlarged shape that provides greater air volume in the cylinder, which increases the pressure in the barrel and thus the performance of the weapon. This set is ideal for weapons with longer barrels or when extending the inner barrel, for example, to a silencer. For optimal performance, we recommend using M130 springs and stronger ones. The set is compatible with other NBU sets, such as Guarder and Systema, and with Tokyo Marui standard mechaboxes. Thanks to high-quality materials and precise workmanship, this set is a great choice for demanding players and technicians.
