CLEANING AND MAINTENANCE
Comprehensive knowledge of how to service and handle
firearms is of great importance. Experience has shown that
most failures, which occur while operating a firearm, are due
to negligence in maintenance. Special attention must be paid
to cleaning, lubricating, and inspecting the rifle; this will de-
termine whether or not the rifle will function properly. In order
to maintain accuracy, the barrel must be maintained properly.
The receivers, bolt carrier group, and other moving parts of the
rifle must be kept clean and lightly lubricated to ensure proper
operation of the rifle.
GENERAL
Ensure the rifle is clear and safe by removing the magazine,
placing the rifle fire selector on “Safe” and cycling the rifle
multiple times to ensure a clear chamber, visually
inspecting the chamber to confirm.
Desert Tech recommends cleaning the barrel
when accuracy begins to deteriorate, using
bore cleaning foam and the properly sized
bore snake. Follow cleaner product
instructions when cleaning the barrel.
Desert Tech recommends cleaning the MDR
every 1000 rounds in clean environments.
Dependent upon environmental conditions,
cleaning more often may become necessary.
Note: When the rifle is purchased, or after it has
been stored for long periods of time, the rifle should
be cleaned before use.
