First, hello to all of you here. Everyone calls me Bob. I am one of the old farts here probably (60). A neighbor wanted to sell her deceased Husbands guns and offered them all to me. I bought them all. One is a Century Arms INC. AR15 with carry handle. is this an (A2)? 20 inch heavy barrell in the box. Opinions on this weapon would be appreciated. Included were 2,000 rounds of ammo, sling and a under the barrell light set up. I have hunted and shot all my life but, I am new to these Black Guns. It shoots well for my old eyes under 2 moa at 100 yards. Now you can unload on me. All info and comments welcome.
