carefully slide  it  over  the  gas  piston  and 
magazine  tube. 
CAUTION:  DO NOT 
APPLY  FORCE  AS  DAMAGE  TO  THE

For  convenience  in  casing  and  carrying  the 
dismantled  gun,  return  the  forearm  to  its 
position  on  the  magazine  tube  and  screw 
on the  forearm cap assembly.  You will  then 
have  two  compact  units.  One  is  the  barrel; 
the  other  is  the  action  with  forearm  and 
stock. 
The cross
-bolt  “safety”  is designed to block the 
trigger from traveling. In the “off

There  are  two  basic  methods  for  getting  a loaded shell  into  the  chamber  of a  B
-80.  First, 
the  shell  can  be  directly  loaded  through  the 
ejection  port.  Second,  a  shell  can  be  loaded 
manually  from  the  magazine.  Loading  of the 
magazine  is  the  same  for  both  procedures. 
CAUTION:  AT ALL  TIMES  DURING  THE 
LOADING  PROCEDURE,  BE  SURE  YOUR 
MUZZLE  IS  POINTING  IN  A  SAFE  DIRECTION 
AND  THE  SAFETY  IS 
ON SAFE.

DO  NOT  PUT  A  20  GAUGE  SHELL  IN A  12 GAUGE GUN. 
Store shells of different gauges in 
completely  separate  and  well
-marked  containers. 
See  caution  number  9  on  page  6  of this  booklet.  Do  not  store shells  of mixed  gauges  in  a 
common  container  or  in  your  pockets. 
LOADING  THROUGH  THE EJECTION PORT— 
Pull  the  operating  handle  to  the  rear  until 
the  bolt  locks  in  the  open  position.  If  the 
bolt  will  not  lock  in  rear,  press  the  carrier 
release....

Insert  the  second  cartridge  through  the 
loading  port  at bottom  of receiver  as  shown 
in  Figure  12.  Note: 
MAKE SURE THAT 
THE  CARTRIDGE  IS  PUSHED  PAST  THE 
CARTRIDGE  STOP,  AND  THE  CARRIER 
IS FREE TO MOVE. 
(See Figure  13.)

Repeat  the  above  procedure  until  your  gun 
is fully loaded. Your B
-80 will hold three 3 
inch  or  three  2  3/4  inch  cartridges  in  its 
magazine plus one in its chamber.  NOTE: 
A magazine plug restricting the B-80’s  magazine  capacity  to  two  cartridges  is 
installed at the factory.  lnstructions for 
removing  the  magazine  plug will  be  found 
on  page  42. 
LOADING  MANUALLY  FROM  THE  MAGAZINE- 
Make sure  the  muzzle  is pointed  in  a safe 
direction.
