Great question—compatibility matters most. Before adding to cart, compare the specs on the product page to your setup. You’ll typically see clear fit notes in the title or description.

• Action length: Look for short vs. long action callouts.
• Rear profile: Some receivers use a round rear, others a flat rear.
• Mounting hole threads: Common sizes include 6-48 and 8-40.
• Built-in cant (MOA): Options like 0, 15, 20, or 30 MOA.
• Ejection port size/spacing: Check measurements listed in the specs.
• Material and height: Aluminum vs. steel, low vs. elevated bases.

When in doubt, review the item’s compatibility section and consider asking a qualified professional to confirm fit.

MOA (Minute of Angle) on a rail refers to built-in elevation cant that can help you keep your scope’s adjustments in an optimal range.

• 0 MOA: Neutral base. A practical choice for closer to mid distances and general use.
• 15–20 MOA: Adds upward tilt, often chosen to extend elevation adjustment for longer distances.
• 30 MOA: More cant for setups focused on extended ranges.

More cant can reduce downward adjustment, which may make close-distance zeroing harder with some optics. It’s a trade-off. Consider your typical distances and your optic’s internal adjustment range. Product pages will list the MOA so you can match it to your needs.

Many bases include mounting hardware, but it’s not universal. Always check the “What’s included” or “Specifications” section on the product page for details.

• Screw threads: You’ll commonly see 6-48 or 8-40 listed. Match the item to your factory threads.
• Length and head style: Verify screw length and head profile match your receiver and base design.
• Use supplied hardware when specified: Mixing thread sizes can damage mounting holes.
• Torque guidance: Follow the manufacturer’s recommendations if provided.

If your mounting holes have been re-threaded or modified, confirm specs before purchasing. When uncertain, consult a qualified professional for a quick check.

A careful, step-by-step approach can help with a clean install. Here’s a general guide—not a guarantee, since setups vary:

1. Dry-fit first: Place the rail and confirm hole alignment without force.
2. Clean threads: Degrease screws and mounting holes if recommended by the maker.
3. Start by hand: Thread all screws in by hand to avoid cross-threading.
4. Torque gradually: Use the correct driver and tighten in a gradual, alternating pattern to spec.
5. Thread locker: Consider a non-permanent option only if the manufacturer recommends it.
6. Verify alignment: Check that the rail sits flush and your optic tracks as expected.

If anything feels off, stop and seek help from a qualified professional.
