This M1100 is modified for sport shooting purpose like 3 guns competition. The body and barrel is changed to aluminum and better rigidity is achieved. It lets shooter feels more secure for 8 rounds course. Special colour job is done on front grip and stock . Adco zero magnification red-dot sight is mounted as well.
Internal modification is limited to power only.
To power charged three shots of BB over 5 meters, ordinary 134a gas is not powerful enough. This M1100 is further modified to handle high pressure green gas from Taiwan. This gun now reaches 1.8j muzzle velocity accompanied with the extended barrel. We hope this Maruzen M1100 is not an end to this type of auto load shot gun. Trigger feel can be further improved and blowback system can also be strengthen for to give better feeling and durability.
