Step 1: Choosing Proper Base & Rings
a. I prefer to use Weaver bases and rings since they have been in the industry for a long time, have a sound reputation, and are reasonably priced for the quality product they produce.
2. Select a set of scope rings to pair with your bases and scope based on the diameter of the tube of your scope. Modern scopes should have a tube diameter of either 30mm or 1 inch. It’s important to note, that since Weaver is an industry leader in the manufacturing of scope bases, alternative brand scope ring manufacturers’ do produce rings which are designed to work in conjunction with Weaver-style bases as long as the rings you purchase are marked as such.
Step 2: Mounting Base and Lower Rings to Rifle
Step 3: Mounting Base and Lower Rings to Rifle
a. Be sure that the extrusion on the underside of the scope ring lines up with the slot in the scope base. It is important to securely fasten the large screw to the base so that the lower half of the scope ring will not move later. (see picture (3) for reference)
