Zoom ring throw lever specifically designed w/ the HAWKE FAST MOUNT 3-9x40 AO's measurements, however, should fit most HAWKE scopes w/ a zoom ring featuring an outisde ø of 41mm, which also has the slabbed protrusion on the ring, which this clamp set primarily affixes onto as its rotational manipulation point. The design doesn't allow for much play and both sides of the rings can be clamped down w/ the included stainless steel M3x12 cheesehead screw and nut. There are counterbores holes for these, which the bolt head sinks into, as well as for the nuts. The sides as well where these go through and sink into, are flush designed, lending the entire design an evenly contoured finish yet w/ positive, double sided bracing.
This part clamps across the total width of the zoom ring and for fitting purposes, the the edges are left 90°. These fit properly over the zoom ring, sitting mostly flush to each side. The throw lever itself has a 23mm ribbed shaft, whose slots, once grasped around w/ the index allows for a positive haptic feedback. This shaft has a diameter of 7.85mm w/ ribbing extending out w/ 2.55mm. The entirety of the handle rises up by 38.75mm off of the mount ring.
The lever itself has a 2.3 x 10 mm hole that is tapped out w/ the supplied M3 stainless steel machine screw, which reinforces the initial length of the lever. Since the screw's threading taps the hole out, the lever therefore sits tight w/ zero play / manoeuverability. The end on the top mount ring also has a counterbore, letting the screw's cheesehead sink in flush and will neither obstruct the fitting of these ring halves nor scratch your HAWKE scope's zoom ring.
Good product, manufactured 65% solid w/ Glycol-modified polyester, sporting a 0.08mm planar resolution on the design for a fine quality / finish on the product whilst also minimizing the weakness along the grainline inherent in FDM molten plastic depositing.
