How did I know this was a rifle....

Funny thing is I sort of just did the same thing. Been long enough since I carried an M4 and I always like my M16a4 I had in basic. FN made and that thing could shoot! Despite its crappy trigger. Shot expert with it at any rate.

Ended up just building my 1st AR because I sort of miss the things. But I totally get the picking the thing up and its an old friend. Similar reaction when I got my parts together and was holding some sort of mutant M4/M16 ar-15 hybrid. Sort of the middle road between the M16a4 from basic and the M4 from everything else. Best part was that it was paid for with VA back pay. My tradition of get cash from the VA and buy a gun continues.... I consider it pain and suffering compensation.
