This is a direct, screw-in replacement for your original Kimber 8400 bolt handle. This may also fit other rifles where the bolt handle attached with an M7 x 1 thread. This very stiff and strong
1-piece carbon fiber replacement is just a hair over half an ounce (15.25 grams) - lighter than the handle on the top-of-the-range Mountain Ascent !
If you are looking at ways at shaving even more weight off these fine mountain rifles, our carbon fiber replacement will achieve the greatest saving without
sacrificing quality or durability as well as offer better grip and leverage than the factory handle. Please read out notes below regarding assembly and guide on tightening the handle to the bolt
The factory handle of Kimber 8400 is threaded directly into the bolt body using a metric M7 x 1 thread. This can be removed by wrapping the original handle in a
strip of thick leather (or vise soft jaws) and securing firmly in a bench vise with the bolt body positioned parallel and just above the vise jaws. If your Kimber has a separate bolt knob fitted
as standard (tactical models) - unscrew this from the handle first before mounting into the vise. The bolt body can now be rotated anti-clockwise to unscrew from the handle. Clean threads if
necessary then screw our replacement 1-piece carbon fiber unit into the bolt body firmly by hand.
(1) The strip of thick leather (or padded vise jaws) serve to grip the bolt handle firmly and avoid marring the finish.
(2) Never use excessive force to unscrew the factory handle as this may result in it breaking / snapping potentially causing a difficult task of removing the remaining stem still threaded into the bolt body.
(3) We recommend using a low to medium strength thread-locking epoxy prior to installing the new handle (purple or blue loctite).
(4) When installing our carbon fiber handle, do not overtighten the handle, as the aluminum threads will strip and fail against the internal steel threads of the bolt body, rendering the handle unusable. Tighten by hand just enough for the shoulder to index and engage the bolt body firmly.
