The Browning Maxus is a gas-
operated, autoloading shotgun
capable of quickly firing up to
five shells (with the three-shot
adaptor removed, using 2¾”
loads), one shell at a time, with
each successive pull of the
trigger. Upon firing, high-pressure gases from behind the shot charge pass through two ports in the barrel,
through the gas bracket and into the gas system, forcing it rearward. As the gas system moves rearward, it
forces the bolt to the rear, operating the action. As the bolt moves rearward, it cocks the hammer and
ejects the fired shell. After full rearward travel, the bolt returns forward, picks up a new shell from the
magazine and chambers it. After the last shell has been fired, the bolt locks to the rear facilitating fast
reloading.
n o m e n c l A t u r e
In conventional firearm terminology the position and movement of firearm parts are described as they
occur with the firearm horizontal and in the normal firing position: i.e., the muzzle is forward or in front;
the buttstock is rearward or to the rear; the trigger is downward or underneath; the rib is upward or on
top. For general parts nomenclature, refer to Figure 1. For specific parts names related to disassembly,
refer to Figure 2.

Be especially careful when cleaning firearms with camouflage, Dura-Touch
®
Armor Coating and other
special finishes. Always prevent these surfaces from coming in contact with cleaning solvents, barrel
scrubbers and other strong chemicals. It is preferable to clean these surfaces with a lightweight gun oil
containing no solvents, or with a damp cloth and mild dish soap (be sure to keep water out of the action).
When cleaning your firearm’s bore and action, protect the external finishes from any contact with
chemicals used. Also, avoid any contact between external finishes and other strong chemicals like those
found in DEET-containing insect repellents, sunscreens, etc. Damage to camouflage, Dura-Touch and
other finishes caused by chemicals is irreversible and not repairable.
c l e A n i n G
Various exposed metal parts of
your new firearm have been
coated at the factory with a
rust preventative compound.
Before assembling your
shotgun, clean the anti-rust
compound from the inside of
the barrel, receiver and the
action/chamber areas. A high-
quality lightweight gun oil is
ideal for removing this
compound, and for giving
