Ah yes old school cool. My favorite old school rifle is the M1 Garand.
Another classic from the past the Avtomat Kalashnikova model of 1947.
But if we're talking civilian rifles you can't beat the classic 1970s Winchester 70.
Or the Remington 870 and it's beautiful simplicity.
Or you can go historical with the first pump action shotgun. The Winchester 1897.
Then there's the classic Colt Python(my dream revolver).
