Tagan Arms TR-83

The TR-83 (and TR-83C) was a Fanaglian firearm designed to replace the Tagan Revolving Rifle and Carbine. It features an improved gas-seal system similar to the previous model. The cylinder moves forward when the gun was cocked to close the gap between the cylinder and the barrel, providing a boost to the muzzle velocity of the fired projectile. Another advantage of this system is that it now allows the weapon to be suppressed - something very few revolvers can do because of the leaking of high-velocity gas through the gap between the cylinder and barrel, defeating the purpose of a sound suppressor.

The most significant change from the Tagan Rifle is the larger seven-shot cylinder, increased from 5 for the Tagan.

Another improvement over the original Tagan Rifle is the return to using iron rather than brass. The brass was originally chosen for its resistance to corrosion and little frictional resistance, though the metal proved inconveniently soft for the extra heat experienced by the barrels of repeating weapons. Also featured are a new, more comfortable stock and trigger assembly, added loops for the easy attachment of a shoulder strap, standard bayonet, and a lighter, more slender wooden handguard for decreased weight.
