I have three Colts. Two old SP-1 sporters (Full length rifle and CAR-15 carbine) and a newer LE6940.
Never had a single problem of any kind with any of them.
And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
