17mm Dovetail Rings Mounting Instructions
17mm Dovetail Rings Mounting
Our Ringsets are manufactured to the highest specification possible using
state of the art machinery, and often exceed original engineering
manufacturers tolerances. It is the purchaser’s decision to mount the Ringset
and optic if they feel competent themselves, or seek advice from their
favoured gunsmith.
Place your unloaded firearm on a stable work surface, preferably mounted in a
suitable gun vice. If no gun vice is available, the firearms own bipod can be
utilised instead. It is now important to ascertain the correct eye relief.
First loosen the clamp screws with the T25 Torx bit supplied, and gently place
the ring with the anti cant bubble onto the rear section of the rifles
dovetail, taking care that it does not foul the bolt handle when worked. It
should move freely at this stage as adjustment may be necessary, and if over
tightened, damage could occur to the rifles finish. When positioning the front
ring, you may utilise the recoil arrestor pin supplied with your ringset if a
suitable location hole is present on the rifles action. The ring should be
placed at a midway point on the dovetail as a starting point if the recoil pin
is not utilised. If the recoil pin is utilised, the location hole on the
rifles action will dictate its position. This pin if required should be
pressed into the hole on the underside of the ring before it is placed upon
the action.
Place the optic into the rings and shoulder your firearm carefully, you may
want to replace the ring caps very loosely to avoid letting your optic fall
out of the mounts whilst doing this. As a guide, it is generally better if the
rings are as far apart as possible to gain maximum strength and stability from
the installation. Your optic should be set at the maximum magnification and if
present, the parallax correction set to infinity. When viewing your optic from
the shouldered position you should be able to see a clear image. If you can
see a dark ring around the ocular lens gently move your optic fore or aft
until this disappears. Great care should be taken at this point to avoid
damage to your optics outer finish. When satisfied, a pencil mark placed upon
the optic as reference to the ring cap location will aid the final stage of
installation. You have now set the correct position for the rings. Remove the
ring caps and optic and tighten the T25 Torx screw on the ring claws to 4Nm.
Now place your optic back into the rings using your pencil datum points as a
guide, then replace the ring caps, and using the T15 Torx bit in your fingers
only, tighten the screws gently and evenly to maintain an equal gap between
ring base and cap. Only light pressure is needed as it is important at this
stage to be able to turn the optic in the rings without damage occurring to
the finish.
It is the installers decision to mount the optic by utilising the anti cant
bubble built into the rear ring to level the rifle, and also a separate bubble
placed upon the optics elevation turret cap, or by shouldering their firearm
whilst viewing a suitable true vertical line, and rotating the optic gently
until the bubble levels align, or the reticle matches the chosen vertical
reference line. Great care should again be taken at this stage to ensure no
damage occurs to the optics outer finish. Once the installer is happy with the
reticle alignment, the ring cap screws should be tightened gently and evenly,
at opposing corners, whilst maintaining an equal gap to both sides, up to the
recommended torque setting of 2Nm. Care at this stage should be taken to
ensure your optic remains level, and doesn’t move during the tightening
process.
Care and Maintenance
When installed correctly, your 17mm Dovetail Rings will give you years of trouble free service but it is advisable and wise to check periodically that all the screws are still at the recommended torque setting due to atmospheric temperature changes.
