Notes
     
1 - Shimming is probably required for perfect scope alignment.
2 - Rear base may require modifications for correct fit to military actions.
3 - Front base may require modification for correct fit.
4 - Gun will have to be drilled and tapped.
5 - Front base screws may need to be shortened by grinding.
6 - May require bolt and/or safety alteration, otherwise firearm cannot function safely and properly. Consult with a qualified gunsmith.
8 - Remove rear sight to use.
9 - The handiest way to pinpoint the correct base for the Win. 52 & Win. 70 Long action Rifles is to check the spacing of the tapped holes for the rear base and compare it to the hole spacing for the front base. Does it have:
HOLE SPACING THE SAME
 Model 52: use 46+ 46, Model 70: use 47+ 46
HOLE SPACING DIFFERENT
  Model 52: use 25+ 57 Model 70: use 49A+ 46
12 - Rifle has Grooved Receiver for Tip-Off Rings.
13 - Ruger Mark II Pistols. Weaver only offers a clamp on base with 1" rings (Pistol Mount System #306). Ruger supplies a short or long base and 1" or 30mm rings w/factory drilled and tapped pistols. Contact Ruger at 602-778-6555 for these items.
   15 - Base accepts Tip-Off Rings only.
16 - TO-9, TO-10 & TO-11 bases accept either Detachable Top Mount Rings or Tip-Off Rings. Each have crossbolt slots and 3/8" grooves for both applications.
17 - Must be factory drilled and tapped.
18 - One-Piece base attaches to barrel and extends back over receiver.
19 - Requires the use of Thompson/Center base adapter.
21 - Rear base is positioned on top of receiver and front base is positioned on the barrel. Drilling & tapping required. One-piece base mounts w/2 set screws & newer guns are factory drilled & tapped.
22 - For shorter tube scopes or red dot scopes use #402 extension front base or one-piece base if available. Extension base allows an extra .689".
23 - WARNING: NOT FOR USE WITH X-FRAME REVOLVERS. USE ON FIREARMS OTHER THAN THOSE LISTED MAY CAUSE INJURY.
24 - Top mount base is designed to fit 12GA models only.
25 - Multi Slot Base
26 - Base listed will NOT fit the 50th Anniversary Commemorative Revolver.
27 - May be necessary to grind down base screws.
28 - Rear base screws must be shortened by grinding
