OPERATING INSTRUCTIONS

Section I. DESCRIPTION OF CONTROLS AND INDICATORS

2-1. DESCRIPTION. The M2 Practice Bolt consists of a Bolt carrier with a fixed Bolt; the intention of which is to convert

the bolt action of the M16 series Rifle from gas operation to blow back operation in order to permit cyclic firing of the lower

powered M862 Plastic Training Round, while disallowing accidental firing of the standard 5.56mm cartridge. Installation

and removal procedures for the practice bolt carrier bolt are the same as those for the standard bolt carrier bolt.
