Indoor smallbore 50ft rifle is supported with the NC200.
The NC100 does not support smallbore rifle, only air gun. Simply put, the steel used with the NC100 is not graded for the higher velocity and force of smallbore ammunition. Furthermore, the integrated backstop for the NC100 is only graded to stop air guns and bb guns.
The NC200 does not include any backstop; customers will have to supply their own external backstop.
