The most certain way to bulge or rupture a shotgun barrel
is to load a smaller gauge shell into a larger gauge chamber.
The smaller gauge shell will not fall completely through
the barrel; its rim is caught by the front of a larger gauge
chamber or at the larger gauge’s choke. Your shotgun will
misfire (with the chamber appearing to be empty). It is
then possible to load the correct gauge shell behind the
smaller gauge shell. If the shotgun is then fired, the result
will be a so-called “12-16, 12-20, 20-28 or 28-.410 burst”
which can cause extensive damage to your shotgun and
possible serious injury to you and others.
We can assume no responsibility for incidents which occur
through the use of shells of nonstandard dimension or
those developing pressures in excess of SAAMI (Sporting

Disassembling your shotgun into its two assembly
components is an ideal way to ready your shotgun for
storage and cleaning. Many luggage-style cases require
doing this. It is also a way to add an extra measure of
safety when storing your firearm.
1. Make sure your shotgun is unloaded and make sure
that the “safety”/selector is in the on safe position.
2. Remove the forearm by pulling outward on the
forearm release latch and pulling the forearm away
from the barrels. Pull the front-most end of the
forearm away and slightly forward, completely
detaching it from the barrel set and the front of
the receiver.
use care when reMoving the ForearM. do not
Pull down too hard on the ForearM or Pull it
away FroM the barrels too Far. doing so May
cracK the ForearM.
3. Grasp the barrels ahead of the receiver and push the
top lever to the right with your thumb. Rotate the
barrels downward until they separate from the
receiver. Be sure to support the barrels and buttstock
carefully. When the barrels are fully down, carefully
lift the hinge portion of the barrels (at the receiver)
upward out of the receiver, separating the barrels from
the receiver (Figure 16).
4. If you are cleaning your shotgun, this is the ideal level
of disassembly.
5. When cleaning is completed, reattach the forearm to
the barrels for storage. This is done very easily when
the barrels are detached. Simply align the forearm
extension along the bottom of the barrel so that the
forearm extension aligns with the rails on each side
of the chambers. Make sure the ends of the rails line
up with the rear top edge of the forearm (Figure 17,
page 17). The forearm can be angled slightly or
positioned parallel with the barrels. Press with even
pressure using both hands, front to back, along the
forearm. As the forearm snaps into position, the
release latch may briefly protrude from the bottom of
the forearm. It will snap down flush with the forearm
when it is secured in position correctly.
