Sight Mounting Options

Sight mounting adjustments include cant settings as well as flexibility in locating the sight along the receiver. There are three pre-set angle adjustments: 0°, 5°, and 10°. This is used to correct the sights to vertical (level the sights) when the shooter holds the rifle canted at an angle.

[Sight mounting bases and forend weights are available from Superior Shooting Systems Inc.]


The sight rail on the TUBB 2000 can be adjusted for cant by loosening the four screws that secure it to the receiver using a 7/64 allen wrench.

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.]
