Bulletpoint Metal 2-Hole AMPS Base Mount with 20mm (0.787 inches) Mounting Ball

What buyers think

Buyer review evidence is strongly focused on stability and build quality. Multiple mentions point to a mount that stays planted over rough roads, potholes, and daily driving, with little to no wobble when an arm and device are attached. Installability is another common theme, with reviewers noting the hardware and fit to Bulletpoint-based mounting grids or compatible setups. There is also a practical compatibility note, where shoppers emphasize ordering the right ball diameter when combining mount parts from different systems.

What this mount is, and how it fits your setup

This is a base plate, not a complete phone mount. The core feature is the 2-hole AMPS-compatible plate combined with an integrated 20mm mounting ball. That means you can attach a compatible arm or device holder to the ball, then secure the base to your dash (or to a compatible grid-style base) using the included hardware.

Compatibility and key specs to confirm first

AMPS pattern compatibility

The mounting plate uses an AMPS-standard pattern (30mm x 38mm). In practice, this is what lets it work with any dash mount base that follows the same AMPS standard pattern. If your existing setup uses that same AMPS pattern, this base is a logical upgrade path.

20mm ball compatibility

The included mounting ball is sized at 20mm (0.787 inches). It is designed to work with Bulletpoint’s 20mm mounting arms and device holders across their 20mm mounting solutions. Reviewers who mixed systems also highlight that diameter matters, so it is worth verifying you are selecting the correct ball size for the rest of your mount components.

Mounting type and environment

It is intended for dashboard mounting, and it is not listed as water resistant, so it is meant for indoor vehicle use where it will not be exposed to rain or direct water spray.

Build quality and vibration control

Because this base is made from laser-cut aluminum and includes a thin rubber strip underneath, it is built to reduce unwanted vibrations and help prevent scratching on the mounting surface. In real-world driving conditions, the most repeated buyer takeaway is that the assembly stays secure rather than loosening or wobbling, even when the vehicle is bouncing over rough terrain.

Installation experience

The kit includes 2 bolts, 2 washers, and 2 nylon locking nuts, designed to make the base install fast. That matters because this is the foundation piece, and a stable attachment point helps the whole arm-and-device setup feel tighter while driving.

Pros and cons for different buyers

Best for

• Drivers who want a metal, stable base for an AMPS-standard phone or accessory mount setup
• People building a dashboard or grid-based mounting system that uses a 20mm ball interface
• Buyers who prefer included hardware and an install that focuses on bolting and locking rather than trial-and-error adhesives

Who should avoid it

• Anyone who expects this product to include a full phone holder or arm, since it is the base only
• Shoppers who are unsure whether their existing mount uses the AMPS-standard pattern and the correct ball diameter
• Users who plan to mount it in a place where it might routinely get wet

Alternatives to consider (based on what you need)

If your main goal is stability, look for a base that uses either the AMPS-standard pattern or a system you already own (so you do not fight compatibility). If you care most about a complete kit experience, you may want to choose a full mounting package that includes the arm and device holder, rather than sourcing parts separately. If budget is your top priority, compare not only the base price, but the cost of the compatible arm or holder you will still need.

Verdict

The Bulletpoint metal 2-hole AMPS base with an integrated 20mm ball is a strong choice for building a sturdy, low-wobble vehicle mount setup. It earns favor with shoppers who prioritize vibration resistance and secure installation, with the main “watch-out” being compatibility, specifically the AMPS pattern and the 20mm ball interface you will pair it with.
