							open,  push  the  cartridge  stop  button, 
making  sure  your  fingers  are  clear  of  the 
ejection  port. 
Push the  “safety”  from  left to  right  or  to 
the  “on  safe”  position.  The  red band  indicating that the  B
-80  is  ready to  fire 
should not show. 
Insert  cartridge  of  the  proper  gauge 
through  the  loading  port  at  the  bottom  of 
the  receiver  up  into  the  magazine  as 
shown in Figure  12.  Make sure the 
cartridge  is  pushed  past  the  cartridge  stop  and  that  the  carrier  is  free  to  move. 
Depress  the  carrier  release  and  cycle  the 
action  by  pulling  the  operating  handle  fully 
to  the  rear  and  releasing  it.  Your  chamber 
is now loaded. 
Repeat  step  four  until  magazine  is  loaded. 
CAUTION:  AT ALL  TIMES  DURING  THE 
UNLOADING  PROCEDURE,  BE  SURE  YOUR 
MUZZLE  IS  POlNTlNG  IN  A  SAFE  DIRECTION 
AND  THE  SAFETY  IS  “ON  SAFE.” 
30  
						

							Pull  the  operating  handle  all  the  way  to  the  rear 
and  eject  the  chambered  cartridge  and  lower  the 
bolt on the empty chamber.  NOTE:  It  is not  necessary  or  recommended  that  the  remaining 
cartridges  be  cycled  through  the  action.  That 
would  necessitate  depressing  the  carrier  release 
after  each  cartridge  is  ejected.  It  is  easier  and 
safer  to  invert your  B
-80,  insert your  index 
finger  into  the  loading  port  and  while  pushing 
slightly  on  the  round  in  the  magazine,  depress 
the cartridge stop.  (See Figure  14.) Ease each 
cartridge  out  until  the  magazine  is  empty. 
VISUALLY  CHECK  THE  MAGAZINE  AND 
CHAMBER  To  MAKE  SURE  THEY  ARE 
EMPTY. 
Gather  ejected  cartridges  and  store 
31  
						

							separately  from  the  gun  beyond  the  reach  of 
children. 
To change loads in your  B
-80,  simply eject the 
chambered  cartridge  by  pulling  the  operating 
handle  all  the  way  to  the  rear.  Insert  the  desired 
cartridge  (such  as  a  goose  load)  of  the  same 
gauge  through  the  ejection  port  into  the  chamber. 
CAUTION: Repeated cycling of the bolt’s 
operating  handle  alone  is  not  assurance  that  the 
B
-80  is unloaded.  There still  may be cartridges  in 
the magazine. 
ALWAYS CONDUCT A THOROUGH 
VISUAL  INSPECTION  OF  THE  CHAMBER, 
ACTION  AND  MAGAZINE  AFTER  UNLOADING. 
The  correct  procedure  for cleaning  your  B-80  is 
as follows: 
BE  CETAIN  YOUR  SHOTGUN’S  MAGAZINE 
AND  CHAMBER  ARE  UNLOADED  AND  WEAR  EYE  PROTECTION. 
Dismount  barrel  so  that  it  can  be  cleaned 
from  the  breech  end. 
Inspect  bore  from  both  ends  for  leading  by 
looking through bore toward light.  NOTE: 
Dull longitudinal streaks,  usually more 
32  
						

							pronounced  in  the  constriction  area  of  the 
choke  and just  forward  of  the  chamber,  are 
caused  by leading. 
A  normal  amount  of  leading  can  be  expected  with  today’s  high velocity loads 
and  improved  wads  but this  is  not serious. If  leading should become  heavy,  it  can  be 
removed  with  a brass  bore  brush.  Spray 
the  bore  or  the  bore  brush  with  a  good 
powder  solvent,  and  scrub  the  bore  until 
leading is removed.  To prevent brass 
bristles  from  breaking off,  the  brush  should 
be  pushed  completely  through  the  bore 
before  being  withdrawn. 
After  leading  has  been  removed,  the  bore 
should  be  wiped  dry  and  then  a  lightly 
oiled  patch  run  through  it  for  preservation.  If  the  gun  has  been  exposed  to  dust,  dirt, 
mud  or  water,  the  principal  working  parts 
should  be  wiped  clean  and  lubricated  with 
a light film of oil.  Browning Oil is 
recommended. 
The  magazine  tube  on  the  B
-80  should  be 
wiped  clean  of  all  dirt  and  grit,  and  then 
lubricated  lightly with  an  oiled  patch. 
Reassemble  the  barrel  and  wipe  all 
exposed  metal  surfaces  with  an  oiled  cloth,  33  
						

							making sure  to  wipe  gun  clean  of all  finger 
marks. 
The  wood  surfaces  can  also  be  wiped  with 
Browning  Gun  Oil  or  they  can  be  polished 
with  any  quality  furniture  wax  (but  not 
both). 
Once  a year,  or after  1000 shots,  it is advisable  to  soak  the  gas  piston  in  solvent  and  scrub  it 
with  a  brass
-wire  brush  to  remove  accumulated 
deposits.  The  gas  cylinder  and  barrel  guide 
should  also  be  thoroughly  cleaned  and  wiped 
dry.  Do not oil.  If at any time your B
-80  should 
fail  to  eject,  thoroughly clean  the  gas  system 
before  seeking  the  services  of  a  competent  gunsmith. 
The  trigger  and  bolt  assembly  should  be 
removed  from  the  receiver  as  described  on  page  35,  and  thoroughly  cleaned  with  nitro  solvent 
and  a  toothbrush.  Wipe  the  parts  dry  and  lubricate  with  a  few  drops  of high  grade  oil 
before reassembly.

							REMOVING  THE  TRIGGER  HOUSING— WHILE  POINTING  THE  MUZZLE  IN  A 
SAFE  DIRECTION,  MAKE  SURE  THE 
CHAMBER  AND  MAGAZINE  ARE  EMPTY. 
Draw  bolt  fully  to  the  rear  and  release  it 
by  depressing  the  cartridge  stop  and  bolt 
release  button. 
Push “safety” to the “on safe” position. 
With  a  punch  or  dowel  push  the  trigger  housing  retaining  pin  from  either  side  until 
it  can  be  grasped  and  pulled  free  by  hand. 
(See Figure 15.) 
35  
						

							Depress  the  cartridge  stop / bolt  release 
button  flush  with  the  receiver  and  lift  the 
trigger  housing  forward,  up,  and  out  of  the 
receiver. (See Figure 16.) 
REPLACING  THE  TRIGGER  HOUSING— 
With  the  bolt  closed,  and  the  trigger  housing 
hammer  cocked,  and  the  safety  in  the  “on  safe” 
position, insert the mainspring support into position 
by  mating  the  projection  at  the  rear  of  the  trigger assembly into the recess inside the receiver. 
(See  Figure  17.)  Depress cartridge stop / bolt 
release  button  and  align  surfaces  until  flush,  then 
replace  the  trigger  housing  retaining  pin. 
36  
						

							HOW  TO  REMOVE  THE  BOLT  ASSEMBLY— 
While  pointing the  muzzle  in  a  safe 
direction,  make  sure  the  magazine  and 
chamber  are  empty. Place the “safety” in the “on safe” position. 
Remove  forearm  and  barrel  as  previously 
described. 
37  
						

							Remove  the  gas piston  by  pulling  it up  and 
off  the  magazine  spring  retainer  and 
forearm  cap  stud. 
Remove  the  trigger  housing  as  previously 
described under “Trigger Housing.” 
Remove  the  operating  handle  by  pulling  it 
straight  out  and  free  of  the  bolt. 
Grasp  the  action  bar  and  sleeve  and  ease 
assembly forward  until  bolt clears receiver. Be  ready  to  catch  bolt  assembly  as  once  it 
clears  receiver  it  will  be  free  to  separate 
into  its  three  basic  components.  .  .  the 
breech  bolt,  bolt  slide,  and  action  bar  and  sleeve. (See Figures 18 and 19.)
