INVECTOR-PLUS
™
CHOKE TUBE SYSTEM
This shotgun is fitted with the Invector-Plus choke tube
system, one of the most popular systems on the market.
This means:
• It has a back-bored barrel.
• It is threaded to accept Invector-Plus choke tubes only.
The Invector-Plus system allows you to configure your
shotgun for the shot pattern and/or choke constriction
your hunting or target shooting situation demands. The
back-bored barrel and highly engineered choke tapers
produce the best possible patterns for target and field
situations. It is extremely easy to switch choke
constrictions to match your shooting conditions.
Invector-Plus tubes are fully compatible with steel and lead
shot. Most Invector-Plus choke tubes fit flush with the
muzzle when installed. A special choke tube wrench is
provided to remove and tighten these tubes. Invector-Plus
choke tubes are NOT interchangeable with any other
choke tubes on the market including chokes listed as
“Standard Invector
™
” or “WinChoke
®
” choke tubes.
USE ONLY CHOKE TUBES MARKED “INVECTOR-PLUS”
IN YOUR SHOTGUN. USE ONLY THE APPROPRIATE
GAUGE OF INVECTOR-PLUS CHOKE TUBES AS MARKED
ON YOUR SHOTGUN.
Failure to follow these warnings may damage your firearm
and cause injury to yourself and others. A special
Invector-Plus choke tube wrench is provided to remove
and tighten Invector-Plus choke tubes.
DO NOT FIRE THIS SHOTGUN WITHOUT HAVING AN
INVECTOR-PLUS CHOKE TUBE INSTALLED. PERMANENT
DAMAGE MAY RESULT TO THE BARREL THREADS.
