The T-77 submachine gun was developed at the state owned 205th Arsenal of Taiwan, a military factory producing a number of various small arms for Taiwanese government forces. It appeared during the late 1980’s and is now widely used by Taiwanese Special forces in both military and Law Enforcement.
The T-77 submachine gun is based on the American Cobray M11/9 submachine gun, which in turn is an evolutionary development of the Ingram Mac-11.
This gun uses simple blowback action, with a fixed firing pin and wrap-around bolt. It fires from an open bolt, in both single shot and fully automatic modes. The fire mode selector is located on the left side of the gun. The manual safety is a small slider located to the right of the trigger. An additional manual safety is provided in the form of a rotating bolt handle at the top, which, once turned 90 degrees, securely locks the bolt in either forward or rearward position.
The receiver is made from stamped steel, and magazines are inserted into the pistol grip. Iron sights consist of a protected front post and an L-shaped flip-up aperture rear sight, which is set for ranges of 100 and 200 meters. Shoulder stock is made from steel and folds to the right. The gun features a compact plastic forend for a more secure grip.
