Looking for my first`AR. Ran across a Colt (forgot to get the model #). I believe a "defender" had 16" barrel, removable handle, adjustable rear sight, flash arrester (bird cage), bayonet lug, 2- 20 round mags, hard case, sling. Supposedly about 20 rounds thru it as was bought and returned as guy needed money back. Out the door price is $1,000.00. Been looking and seems a reasonable price. Any input appretiated.
