When the A2 version was first shown in American Rifleman back in 1982 I wanted one really bad. Of course I was just a young pre-teen at the time so I had to wait awhile. When I finally came of age and could afford one I bought a Bushmaster 20" HBAR, and the thing was extremely accurate (one 100yd group I fired was less than an inch). Unfortunately I had one of many lapses of bone-headedness and sold it during the ban years. It wasn't until recent years that I had a hankering for another M16A2 clone, but by then virtually nobody still offered one. They were all the A3 version with a removable carry handle, which was close but not quite. So I ended up buying a Windham A3 20" Government rifle, swapped the upper receiver for an A2 type, and viola! I finally had an A2 again. It's not an HBAR and doesn't seem to be quite as accurate as my original Bushmaster was, but since I was merely trying to scratch that A2 itch again I'm not complaining.
