Section II. EQUIPMENT DESCRIPTION

1-4. PRINCIPLES OF OPERATION. The M2 Practice Bolt replaces the standard M16 series Rifle Bolt to enable plastic

practice ammunition to be fired.

When firing the (M862) Plastic Practice Cartridge, the M16 series rifle is converted from gas operation to blow back

operation. The Plastic training ammunition enables realistic firing training to be carried out at shorter distance with

reduced danger areas.
