Because, when it was manufactured back in 1970, that's how they came from the factory in China. It also has a built in compartment in the butt stock that houses the cleaning kit. All in all it's a nifty little rifle.
It's more of a historical collectors piece than anything else. For now. Until I get my Tapco synthetic mod and turn it into something a bit more tactical.
