What is the correct sequence of steps for a basic field strip on the M16/M4 for cleaning?

• A. Ensure safe; remove the magazine; separate the upper and lower receivers to access the bolt carrier group; remove the bolt carrier and charging handle; clean parts; reassemble.
• B. Remove the magazine; ensure safe; reassemble; separate upper and lower receivers; clean parts.
• C. Separate upper and lower receivers; remove the bolt carrier and charging handle; ensure safe; clean parts; reassemble; remove the magazine.
• D. Ensure safe; remove the upper receiver; separate lower; remove the bolt; clean; reassemble.

Answer: (A)

This question is testing the proper order for safely field-stripping an M16/M4 to clean the major components. Start by treating the weapon as unsafe until you’ve confirmed it’s clear: remove the magazine, visually and physically check the chamber, and set the selector to safe. After that, you remove the magazine (already done) and separate the upper and lower receivers to gain access to the bolt carrier group. With the receivers split, you can remove the bolt carrier and charging handle, which exposes the parts that need cleaning. Clean all parts, then reassemble in reverse: reinstall the bolt carrier and charging handle into the upper, join the receivers, and ensure everything is properly seated. This order keeps safety in front, exposes the bolt carrier group for cleaning, and ensures reassembly is straightforward.
