Cobray Flare Launcher M203? Pictures below. I bought it on AR15.com, but doesn't fit my 14.5 M4 without minor modifications. Came off of a Shorty Colt, I believe, but I understand it will fit a rifle too. Good condition and fire pin hits hard. I haven't fired it, but don't see any reason it wouldn't work. Email me with questions. Sold.
"The character inherent in the American people has done all that has been accomplished; and it would have done somewhat more, if the government had not sometimes got in its way." -- Henry David Thoreau (1817-1862)
