New features include the unique weight of 9.2 pounds for CT and 9.9 pounds for CL, [ 12 ] a rounds counter, and a highly stiff and heat resistant barrel ...
Barrel tensioning devices are a way of gaining stiffness with minimal increases in weight. They do this by placing a lightweight sleeve, often made of aluminium or a carbon fiber composite, around the barrel, and then using a nut attached to the end of the barrel to tension the barrel and place the sleeve under compression. This serves to keep ...
Rifles are usually custom-made with extreme accuracy in mind. Shooters might use heavy stainless steel barrels, scopes with high power magnification, and handmade stocks of graphite, fiberglass, or carbon fiber. Triggers are usually set to a pull of only a few ounces.
FAL rifles have also been manufactured in both light and heavy-barrel configurations, with the heavy barrel intended for automatic fire as a section or squad light support weapon. Most heavy barrel FALs are equipped with bipods, although some light barrel models were equipped with bipods, such as the Austrian StG 58 and the German G1, and a ...

Folding stock and pistol gripped model with a 20" Tribore barrel, no heatshield, receiver-mount Picatinny rail, and a large flip-up blade sight.
U.S. Army Ordnance issued a requirement for a "light rifle" with greater range, firepower, and accuracy than the M1911 pistol while weighing half as much as the M1 Garand. [11] As a result, the U.S. developed the semi-automatic M1 Carbine and shortly thereafter the select-fire M2 Carbine. Widely employed until the end of the Vietnam War, these ...
