  A:

  Hector, If you mean a 'full auto' (M16) BCG then yes. This BCG has the full mass (no cut out) to help control the cyclic rate of the rifle. Instead of the cut out lower mass BCG that speeds up cyclic rate of fire. Obviously buffer and spring weights effect that also. But without the cutout it could function in select fire rifle.
