Why Choose the Seekins 20 MOA Scope Base Short Action 8-40?
A quality scope base is the foundation of an accurate rifle. Seekins machines its one-piece bases from solid aluminum so the mounting surface is straight and true, which helps your rings line up without putting stress on the scope tube. One-piece construction also gives your rings a full-length Picatinny rail, so you can fine-tune eye relief by moving the rings forward or back one slot at a time.
This 20 MOA base has built-in forward cant that adds elevation to your scope before you touch the turret. That extra travel lets you dial for long-range shots without running out of adjustment, and it is one of the easiest ways to set a rifle up for extended distances.
Installation Tips
Degrease the receiver holes and base screws, apply a small drop of medium thread locker and torque the screws evenly to the manufacturer’s spec, working from the center outward. Check that the base sits flat with no rocking before you mount rings.
How to Choose the Right Scope Base
Choosing optic mounting hardware starts with three questions: what diameter is your scope tube, how much elevation do you need, and how high must the scope sit to clear the barrel? Match the tube size first (30mm, 34mm or 35mm), then pick the lowest height that gives the objective bell clearance. If you shoot past 600 yards, a 20 or 30 MOA base or mount gives you extra elevation travel. Finally, think about weight and durability. Seekins hardware is machined from aluminum and anodized, so it stays strong and light without corroding.
