Double Carbine

First: The M7 is not a rifle, it's a carbine.  It's in the same series as the M1 and M4 carbines.

I have long giggled about the M1 carbine not actually being a carbine because a carbine is traditionally a shorter version of a rifle.

The M1 Carbine isn't a shorter version of anything.

I noticed, and mentioned, that the M4 was a real carbine because it was a short M16.

The M7 isn't a shorter anything and I don't know where on the rifle list it should come out if you wanted to call a 13.5" barreled gun a rifle.  M111 since there's a Knight's Armament M110?  Higher?  Dunno.

That makes this really funny is the M7 has finally had troop and field trials in the form of issuing them to the 101st Airborne.

They felt it was too heavy and too long.

So SIG is lopping 2" off the barrel and ditching the folding stock give us the XM8 Carbine (no relation).

A carbine version of a carbine.
