The Kel-Tec Sub 2000 rifle actually folds down to fit in a smaller package.
This gun will shoot your choice of 9mm or .40 caliber flavors.
The Kel-Tec Sub 2000 is the little rifle that could as Hickok45 shows us in this video.
The Kel-Tec Sub 2000 is just an incredible little rifle. It will actually fold in half with no tools necessary for portable carry.
Hickok45 fires this little gun at distance shots against steel plate targets. He hits them pretty far out too. The Kel-Tec Sub 2000 is available in different magazine configurations and in 9mm or the .40 Smith and Wesson cartridge.
Personally, I have fired two such models many times and can vouch they are indeed great little rifles. There are even ones that take the Glock 9mm 33-round magazine too. Now that is a lot of fun on target.
