Semi-automatic rifle - Wikipedia
In 1903 and 1905, the Winchester Repeating Arms Company introduced the first semi-automatic rimfire and centerfire rifles designed especially for the civilian market.
Over 100 years ago
You can introduce it till your're blue in the face but the fact remains that the first popular civilian produced semi auto was the Marlin Model 60. But there were already a few M-1s floating around but they weren't produced for just civilian use. The Gas Operated Semi Autos rewrote the semi autos in 1937 which the M-1, SKS, AK and the Model 60 is based on. The ones before that were the blow back models and weren't really sought after. You really need to step away from Wiki and get out and live a little, cupcake.
the Model 1903 achieved commercial success and continued to be manufactured until 1932 when the Winchester Model 63 replaced it.
Commercial success
You still insist that the world is as YOU say it is
IOW you are fucking delusional
You can type real big if you want to but the fact remains, it was a dismal failure because it was just too early. It was a blowback model and didn't work real well. It jammed way too much. The Gas Discharge of the Marlin Model 60 was not possible (it was released in 1962) until the Gas Discharge method was invented in 1937 which many of the modern semi auto rifles of today are based on including the SKS, AK, M-1, M-14 and many others.
Once again just because you say something doesn't make it true
Semiautomatic rifles have been available to the public for over 100 years and nothing you can say or make up can change that fact
The first car was invented in 1795 but does anyone really remember who the inventor was? It was Nicolas-Joseph Cugnot. Why didn't it catch on? It sucked the big one. It wasn't until 1885 that Karl Benz introduced a 3 wheeled car that was hand mass produced in Germany that the Automobile finally caught on. While not the greatest, it just sucked a whole lot less. Each year, the Automobiles produced around the world sucked less and less until the Model T came out and it no longer sucked nearly as bad. Blowback is like the car built in 1795. Yes, it works but it really, really sucks and doesn't really replace the horse and buggy or in the blowback's case, the pump or bolt action.
