In the next 2–3 years, MGC added some more models to its product line and wholesale its modelguns to other re-seller companies and sold under individual brand name. In 1965, MGC started to sell its products in its own shop "MGC Bondshop". Meanwhile, 7 re-seller companies notably Nakata, Tokyo CMC, Hudson, Kokusai and Malugo formed an allied association Nippon Kokyu Gangu Kumiai (NKG) or Japan Premium Toy Retailers' Union and stopped buying products from MGC. In 1966, the NKG member companies started to compete directly with MGC starting with non-movable paperweight models (mainly by Nakata, but strictly speaking not modelguns) and shortly later some copied MGC products by some NKG members. The competition heat was intensified when NKG members also had their own design of models which were produced by a modelgun manufacturing company Tokyo Replica Corp. (TRC) formed by Marushin Die Casting Industry and Nakata as joint venture. Since then, the modelgun industry boom accelerated and popularity grew tremendously. The first major change in the Firearms and Swords law in 1971 did not have much impact to the growth trend.
