M16 M2 Practice Bolt Operator’s and Organizational Maintenance Manual
The M16 M2 Practice Bolt is a device used to convert the bolt action of the M16 series Rifle from gas operation to blow back operation. This allows for the firing of the lower powered M862 Plastic Training Round, while disallowing accidental firing of the standard 5.56mm cartridge. The design of the M16 M2 Practice Bolt enables realistic firing training to be carried out at shorter distances with reduced danger areas.

WARNING
Fire only plastic training ammunition M862 when using M2 Practice Bolt.
Do not attempt to force feed a service cartridge into the chamber. Doing so would produce dangerous pressures for a blow-back system, damage to weapon and serious injury or death.
To prevent shooter from being hit in the face from ejected brass or excessive flash from burning propellant, the cartridge deflector MUST be used when firing M862 Plastic Training Ammo.
Spent case deflectors should be periodically inspected and removed when excessive wear warrants it.
Be careful where you point a rifle loaded with plastic training ammo! It’s dangerous up to 250 meters down range!
Double hearing protection is required when firing the M862 Practice Cartridge.
Read this manual carefully before handling, loading, or operating the M16, M16A1, or M16A2 rifles when using the M2 practice bolt.

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines:
