The Winchester Model 100 semi-automatic rifle was introduced in 1960 in cal. .308 Winchester. This rifle is gas-operated and has a detachable box magazine. The rotating bolt has 3 large locking lugs. Ejection of fired cases is to the right.

The gas system of the Model 100 resembles that of the Ml4 Service rifle in that it has an expansion chamber which allows a gradual build-up and expansion of gas against the piston. This gives a smoother push to the operating parts than would be the case if the gas acted directly upon a flat piston head as in the Ml Service rifle. No adjustment of the gas system is required when changing from one commercial loading to another and this rifle will function well with handloaded ammunition of adequate power.

By virtue of its relatively short 22" barrel and good balance, the Winchester Model 100 is noted for its excellent handling qualities.
