KUAN JU WORKS: Also known as “KJ Works”, this popular Airsoft gun manufacturer is based in Taiwan. Highly regarded for their gas blowback pistols (GBB), their guns are reputable for their reliability and durability under extreme war game conditions. The KJW products are relatively inexpensive in price and are made from primarily metal construction, making them a popular choice among buyers. Their guns do not carry replicated trademarks making their cosmetic replication somewhat questionable.

KSC/KWA: KSC and KWA are Eastern manufacturers of Airsoft guns. They are primarily known as a pistol manufacturing company. Although recognized as two separate companies they are supposedly one. The company is largely based in Taiwan where it produces all its replicas, selling only the KSC versions of its guns to Japan. This is probably due to the strict import/export laws between the two nations.

MARUZEN: One of the earliest Airsoft gun manufacturers, Maruzen is a Japanese company with a very popular line of APS Sniper rifles. They are also known for a strong line of non-blowback guns including the P99.

MARUSHIN: This Japanese manufacturing company is very popular in the East. Their line of Airsoft guns are also known as the “Shins” which is an obvious derivative of the company name. Some of their Airsoft guns fire 8mm BBs instead of the traditional 6mm.
