DAVID TUBB --
Through
a combination of previous schooling and
traditional rifle designs, many shooters
are leery of canting their rifles, and
even more so if there is no facility for
canting. I, on the other hand, cannot
imagine firing an upright rifle! Canting
is a tremendous help to attaining a good
shooting position, in any shooting
position. I believe you will find that the
maximum (10-degree) angle on your TUBB
2000 will most likely be the best position
for you. I urge you to start there and
adjust the rifle back toward level if
you're not comfortable with that much cant
rather than starting level and working the
rifle over toward a stronger
cant.

The 2000t comes
with a cant indicator mounted on the
muzzle. Loosen its clamping fixture and
level it after all other adjustments are
made. Do not overtighten this
part!

Step
by Step
Following is the
recommended sequence to optimally adjust
your TUBB 2000 to provide a perfect
fit.
Adjusting the TUBB
2000 stock requires the use of a 5/32
allen head wrench.
Cant adjustment is
best accomplished when the sights aren't
yet mounted on the rifle! This helps
ensure that you can find your most
comfortable shooting position without
being distracted by the sights themselves.
Get the rifle into
your shoulder in a comfortable shooting
position. [Each shooting position will
require specific adjustments, but prone is
a good place to start in making initial
determinations.] Make rudimentary
stock length and buttplate adjustments to
get the rifle to fit within a workable
range. These settings will be refined
later.
1. Determine
natural hold and grip angle. This is the
first step in attaining an efficient and
stable shooting position. Rotate (cant)
the rifle counterclockwise until you are
comfortable with your hand gripping
position.
2. Adjust the
forend level by rotating it to suit your
position. Loosen the large knurled ring
that secures the forend to the receiver.
Rotate the forend tube until it locks into
one of three pre-set positions that are
controlled by a stop pin. Retighten the
collar after selecting a position. This
part needs only to be hand tight: do not
overtighten or use tools to tighten the
collar ring.
3. Now work
on getting a head position that you like.
Adjust cheekpiece height by raising or
lowering the cheekpiece by rotating the
knurled ring on the center
strut.
4. Loosen and
remove the four 7/64 inch allen head
screws that attach the sight rail to the
receiver. Now level the rail by choosing
the nearest mounting angle that fits your
shooting style and reattaching and
tightening the mounting rail to the rifle
receiver. Install the iron sight base
(sold separately) at a position along the
rail that affords correct eye relief. Make
sure the base is fully engaged in the
corresponding slots on the sight rail
prior to tightening the sight base
clamping screws. Then attach your sight to
the base using the mounting screw or
screws that came with the sight.
[Scope sight
users follow the same procedure.]
5. Install
the front sight assembly (sold separately)
by sliding it onto the turned section at
the muzzle. Level the front sight and
secure it to the barrel by tightening the
allen screw. The globe supplied with your
front sight base is a 22mm diameter. The
sight assembly includes a selection of
aperture inserts, and there are several
custom inserts available for it (not
included).
You should now
have your TUBB 2000 molded to conform to
your body and shooting style. Enter your
settings in a notebook.

Don't
overtighten the sight onto the
barrel. It can constrict the
muzzle. Use the index ring if you
wish to remove and reinstall the
front sight.

[NOTE:
An optional rear sight base is
available with a 2-1/2 degree
cant built in to add this amount
of additional angle to each sight
mounting
position.]
