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 for prop-er installation (FIGURE 28).

WARNING: A SCOPE WHICH IS NOT SECURELY MOUNT-ED MAY BECOME DETACHED UPON RECOIL OF THEFIREARM. IF IT BECOMES DETACHED IT MAY FLY BACK

AND STRIKE THE SHOOTER OR A BYSTANDER AND CAUSEINJURY. OBSERVE THE CONDITION OF ALL THE SCOPEMOUNT SCREWS AFTER FIRING. IF THE MOUNTING SCREWSSHOW SIGNS OF LOOSENING DO NOT FIRE THE FIREARMAGAIN; TAKE IT TO A QUALIFIED 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 CONTINUED

• 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 changed outfor another barrel. The one rear cross-bolt ties the base rigidly to thereceiver. This one bolt needs to be removed to allow the barrel to beremoved from the receiver. See section in this manual for details on thebridge-type scope mount base system. T/C suggests using low ringswith the LOC™ bridge-type mount to provide proper eye relief.

MAKING TRIGGERADJUSTMENTS

WARNING: ALWAYS ENSURE THAT THE FIREARM ISUNLOADED BEFORE ADJUSTING THE TRIGGER OR DRYFIRING.

NOTE: The T/C Dimension® trigger pull is user adjustable for weightof pull. The trigger pull has beenset at the factory with properover-travel and sear engagement.

• After determining that thefirearm is unloaded proceed asfollows:

• 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).

CONVERSION PARTS• The T/C Dimension® is a modular design. Each of the four (4)

interchangeable parts will have a letter marking that indicates thatit is to be used with similarly marked parts (FIGURES 32-35).

WARNING: ALWAYSENSURE THAT THEFIREARM IS ASSEM-

BLED USING PARTS WITH THESAME LETTER CODE MARK-INGS ON THE INTERCHANGE-ABLE PARTS. A MIX OF LETTERCODES COULD RESULT IN ADANGEROUS COMBINATION,POSSIBLY RESULTING ININJURY AND/OR DEATH TOTHE SHOOTER ORBYSTANDERS AND DAMAGETO PROPERTY.

• The stock and receiver are thesame for all calibers. The lettercodes designate “families” ofcartridges that share commonlengths and case dimensions.These common sizes allowthem to function correctly in therifle with appropriately markedparts.

WARNING: NEVER USEAMMUNITION NOTSPECIFICALLY DESIGNATED FOR USE IN YOUR

FIREARM. FAILURE TO USE THE CORRECT TYPE OR CALIBEROF AMMUNITION MAY CAUSE THE FIREARM TO JAM, FAIL TOFIRE OR EVEN GENERATE EXCESSIVE PRESSURE WHICH CANDAMAGE OR EVEN RUPTURE YOUR FIREARM, CAUSING PER-SONAL INJURY, DEATH OR PROPERTY DAMAGE.

• The cartridge/caliber marking on the barrel must be strictlyadhered to. The marking on the barrel is specific to one cartridgeand that is the only one that should be used in that barrel.
