BGA 20MOA Extended Rail with 6-48 & 8-40 Screws for Precision Rifles

The Bergara BGA 20MOA extended rail is a precision-mounting solution built for shooters running long-action setups who demand elevation adjustment built into their scope base. This 20MOA cant rail gives you a head start on vertical adjustment—critical when stretching shots at distance or dialing for elevation on steep terrain. The extended length provides extra real estate for modern scope rings and accessories, giving you flexibility in sight picture and recoil management whether you're building a long-range hunting rifle or setting up a precision target gun.

Bergara designed this rail to integrate seamlessly with Remington 700 long-action platforms, one of the most popular bases in precision rifle building. The two included screw options—6-48 and 8-40—give you the fasteners you need whether you're working with standard Rem700 receivers or variations that call for different hardware. This means less hunting for the right screw size and more time at the range dialing in your setup.

If you're a long-action rifle builder or upgrading your existing Rem700-compatible rig, this extended rail with integrated 20MOA cant eliminates the need to source a separate base and saves you from stacking shims or epoxy to achieve elevation lead. It's a straightforward way to get the angle you need built in from the start.

Frequently Asked Questions

Is this rail compatible with my Rem700 long-action rifle?

Yes—this rail is designed to fit Remington 700 long-action receivers. The included 6-48 and 8-40 screws cover the most common fastener sizes for these platforms, though you should verify your specific receiver specs before ordering.

What does 20MOA cant mean and why do I need it?

The 20 minutes of angle (MOA) built into the rail creates a mechanical elevation lead, tilting your scope base forward. This lets your scope's elevation turret access more of its usable adjustment range for long-distance shots without maxing out at the top of the turret's travel—essential for true long-range hunting and precision shooting.

Why is the rail length described as extended?

The extended design provides more real estate along the receiver for positioning scope rings and mounting accessories, giving you greater flexibility in eye relief and allowing for larger objective bells or secondary mounts without crowding or interference.
