When I was 11C on active duty, I also cut mine out. As I didn't normally carry an M-16, I carried other crap in there- pocket knives, compass, nail clipper, food bars, candy, smokes, lighter, 1/2 pints, camo stick, blistex, doobie, etc.
Of course, I had to buy new ones and turn them in as "servicable".
