Always be sure of where the bullet will strike andshoot only where there is a safe back stop free of obstructions,water or other surfaces which can cause ricochets. Be sureyour bullet will stop behind your target. Bullets can glance offmany surfaces like rocks or the surface of water and travel inunpredictable directions with considerable velocity. Do not firerandomly into the sky.

• NEVER CROSS OBSTACLES SUCH AS FENCES ORSTREAMS WITH A LOADED FIREARM. Always make certainyour firearm is unloaded before crossing a fence, climbing atree, jumping a ditch or negotiating other obstacles.

MOUNTING A SCOPEWARNING: ALWAYS ENSURE THAT THE FIREARM ISUNLOADED BEFORE INSTALLING A SCOPE OR ANYOTHER ACCESSORIES. FAILURE TO DO THIS CAN CAUSE

PERSONAL INJURY OR DEATH TO YOU OR OTHERS.

We recommend that you have a competent gunsmith install yourscope and mount.

The T/C Dimension® is factory equipped with Weaver-style scopemount bases. These bases accept a ring and scope combinationof your choice. Different scopes have varying lengths of recom-mended eye relief. You need to choose a combination that allowsfor adequate clearance between the scope and your eyebrow.Follow the instructions supplied with the scope and rings forproper installation (FIGURE 28).

WARNING: A SCOPE WHICH IS NOT SECURELYMOUNTED MAY BECOME DETACHED UPON RECOILOF THE FIREARM. IF IT BECOMES DETACHED IT

MAY FLY BACK AND STRIKE THE SHOOTER OR ABYSTANDER AND CAUSE INJURY. OBSERVE THE CONDI-TION OF ALL THE SCOPE MOUNT SCREWS AFTER FIRING.IF THE MOUNTING SCREWS SHOW SIGNS OF LOOSENINGDO NOT FIRE THE FIREARM AGAIN; TAKE IT TO A QUALI-FIED GUNSMITH FOR ASSISTANCE.

WARNING: FIRING A SCOPED FIREARM WITH YOUREYE TOO CLOSE TO THE SCOPE EYE PIECE, OR FAIL-ING TO HOLD THE FIREARM SECURELY AGAINST

RECOIL, MAY RESULT IN SERIOUS PERSONAL INJURYINCLUDING, BUT NOT LIMITED TO, BLINDNESS.

SCOPE MOUNT CONT’D

A LOC™ bridge-type scope mount base is offered as an accessory(FIGURE 29). The advantage of the bridge-type system is that the“sighted-in” scope stays with the barrel when the barrel is changedout for another barrel. The one rear cross-bolt ties the base rigidly tothe receiver. This one bolt needs to be removed to allow the barrel tobe removed from the receiver. See section in this manual for detailson the bridge-type scope mount base system. T/C suggests using lowrings with the LOC™ bridge-type mount to provide proper eye relief.

MAKING TRIGGERADJUSTMENTS

WARNING: ALWAYS ENSURE THAT THE FIREARM ISUNLOADED BEFORE ADJUSTING THE TRIGGER ORDRY FIRING.

NOTE: The T/C Dimension® trig-ger pull is user adjustable forweight of pull. The trigger pullhas been set at the factory withproper over-travel and searengagement.

• After determining that thefirearm is unloaded proceedas follows:

• Trigger “Weight of Pull” adjust-ment can be made by firstremoving the bolt from thereceiver to gain access to the adjustment screw (FIGURE 30). The appropriatetool is included in the box fromthe factory (FIGURE 31).

MAKING TRIGGER ADJUSTMENTS CONT’D

• Turn the screw clockwise (as viewed from the top of the rifle)to increase the trigger pull force required. A trigger adjustmenttool is provided with the T/C Dimension® rifle (FIGURE 29).

• Turn the adjustment screw counter-clockwise to decrease thetrigger pull force required.

• After each adjustment, with the chamber empty and the riflepointed in a safe direction, dry fire the rifle until the desired pullis achieved.

• Do not attempt any other trigger adjustments. When turning theadjustment screw, once resistance is met, do not force thescrew to turn further in either direction.

DRY FIRING NOTE

CLEANING &MAINTENANCE

WARNING: ENSURE THAT YOUR FIREARM ISUNLOADED BEFORE BEGINNING TO CLEAN IT. (SEE“INSPECTING YOUR FIREARM” SECTION). ALWAYS

FOLLOW THE FUNDAMENTAL NRA RULES OF SAFEFIREARM HANDLING.

WARNING: WEAR EYE PROTECTION SPECIFIED FORFIREARM USE EVERY TIME YOU CLEAN OR MAIN-TAIN YOUR FIREARM.

• Before using your firearm for the first time, it should be cleaned.

• Your firearm was treated at the factory with either a preservative oroil to protect it against corrosion during shipping and storage.

• Preservative and oil should be wiped from the bore, chamber andexposed areas using a clean swab or patch before using the firearm.

CAUTION: Never disassemble your firearm beyond the instructionsin the Field Stripping and Inspection sections of this manual.

• Purchase cleaning supplies from your firearms dealer that arespecifically designated for your type and caliber of firearm.Many suppliers offer these in kit form for your convenience.

• Follow the instructions provided with your cleaning supplies.

NOTE: A basic firearm cleaning kit should include: a brass borebrush and a cleaning jag of appropriate size for the bore beingcleaned, high-quality gun cleaning solvent and gun oil/lubricant,cotton cleaning patches and a cleaning rod that is long enough to push the brush and jag completely through the barrel.

• Remove excessive firing residue from the bore and chamberusing a properly fitted brush.

• Clean the exterior of the firearm using a non-abrasive cleaningcloth.

• After cleaning, lightly coat the metal parts, internal and externalwith a firearm oil.

Whenever your firearm has been exposed to sand, dust, extremehumidity, water or other adverse conditions, it must be cleanedand lubricated.

WARNING: ALWAYS HAVE ADEQUATE VENTILATION.CLEANING FIREARMS IN POORLY VENTILATEDAREAS, DISCHARGING FIREARMS, OR HANDLING

AMMUNITION MAY RESULT IN EXPOSURE TO LEAD ANDOTHER SUBSTANCES KNOWN TO CAUSE BIRTH DEFECTS,REPRODUCTIVE HARM AND OTHER SERIOUS PHYSICALINJURY. WASH HANDS THOROUGHLY AFTER EXPOSURE.


24

CLEANING & MAINTENANCE CONT’D

• Run a few patches saturated with good quality firearm cleaning sol-vent through the bore, preferably from the chamber end to avoiddamage to the rifling at the muzzle. Use of a bronze bore brushmay be required periodically. More extensive cleaning, especiallyafter the T/C Dimension® has been subjected to rain or snow,would include wiping all of the external metal surfaces with a drycloth, followed by a light coating of oil. If the internal componentsrequire cleaning, it is recommended that you return the firearm toThompson/Center’s Service Department.

CAUTION: Always follow the instructions provided with your firearmcleaner and firearm lubricant.

CAUTION: Some cleaners can cause damage to your firearms. Youshould avoid prolonged solvent immersion and prolonged ultrasoniccleaning of your firearm. Choice of solvent should be restricted tothose products specifically developed for firearms maintenance.Damage to a firearm’s finish may occur if these cautions are ignored.Ammoniated solvents or other strong alkaline solvents, should not beused on any Thompson/Center firearm.

WARNING: NEVER MANIPULATE, ADJUST OR CHANGEANY OF THE INTERNAL COMPONENTS OF YOURFIREARM UNLESS SPECIFICALLY DIRECTED TO DO SO

IN THIS MANUAL. IMPROPER MANIPULATION OF ANY INTER-NAL COMPONENT MAY AFFECT THE SAFETY AND RELIABILITYOF YOUR FIREARM AND MAY CAUSE SERIOUS INJURY ORDEATH. IT ALSO VOIDS YOUR WARRANTY.

CONVERSION PARTSThe T/C Dimension® is a modular design. Each of the four (4) inter-changeable parts will have a letter marking that indicates that it isto be used with similarly marked parts (FIGURES 32-35).

WARNING: ALWAYSENSURE THAT THEFIREARM IS ASSEM-

BLED USING PARTS WITHTHE SAME LETTER CODEMARKINGS ON THE INTER-CHANGEABLE PARTS. A MIXOF LETTER CODES COULDRESULT IN A DANGEROUSCOMBINATION, POSSIBLYRESULTING IN INJURYAND/OR DEATH TO THESHOOTER OR BYSTANDERSAND DAMAGE TO PROPERTY.

The stock and receiver are thesame for all calibers. The lettercodes designate “families” of car-tridges that share commonlengths and case dimensions.These common sizes allow themto function correctly in the riflewith appropriately marked parts.

WARNING: NEVER USEAMMUNITION NOTSPECIFICALLY DESIG-

NATED FOR USE IN YOUR FIREARM. FAILURE TO USE THECORRECT TYPE OR CALIBER OF AMMUNITION MAY CAUSETHE FIREARM TO JAM, FAIL TO FIRE OR EVEN GENERATEEXCESSIVE PRESSURE WHICH CAN DAMAGE OR EVEN RUP-TURE YOUR FIREARM, CAUSING PERSONAL INJURY, DEATHOR PROPERTY DAMAGE.

The cartridge/caliber marking on the barrel must be strictly adheredto. The marking on the barrel is specific to one cartridge and that isthe only one that should be used in that barrel.
