Ruger American G2SA Arca Rail for Short Action Stocks
$149.00
The G2SA is a 10.25-inch full-length Swiss Arca rail designed specifically for Ruger American Gen 2 short-action Standard, Ranch and Predator factory stocks. CNC machined from 6061-T6 aluminum, the rail follows the factory stock contour for increased contact and rigidity and installs using SRA's drill-guide-assisted mounting system.
Quantity
Will This Fit My Rifle?
✓ FITS
Ruger American Gen 2 short-action factory stocks, including Standard, Ranch and Predator models. Designed for short-action rifles with approximately 4.046-inch action screw spacing.
✕ DOES NOT FIT
Ruger American long-action rifles with approximately 4.578-inch action screw spacing, Ruger American Rimfire models, or aftermarket stocks that do not retain the compatible factory mounting geometry.
? HOW TO VERIFY
Not sure whether your rifle is short action or long action? Measure the center-to-center distance between the front and rear action screws. Compatible Ruger American Gen 2 short-action rifles measure approximately 4.046 inches. Long-action rifles measure approximately 4.578 inches and require a different SRA rail.
Model-Specific Contour Match

Why Contour Matching Matters
Most accessory rails are designed as universal mounting solutions, using a relatively flat mounting surface against a curved or irregular factory stock.
SRA takes a different approach. We use 3D scanning technology to capture the actual geometry of the factory stock and create an accurate digital model. That model is then brought into CAD and used as the foundation for the rail design, allowing us to precisely shape the underside of the rail to match the stock's unique contour.
This creates substantially more contact between the rail and stock, distributing mounting forces across a larger area rather than concentrating them around individual mounting points. The result is a more rigid, integrated mounting platform with less opportunity for the factory polymer stock to flex under tripod or bipod load.
Just as importantly, the rail looks and feels like it was designed as part of the rifle—not added to it as an afterthought.

Additional Benefits
Increased Fore-End Rigidity
The full-length aluminum rail reinforces the factory polymer fore-end, increasing rigidity and helping reduce unwanted stock flex. The more rigid platform helps maintain clearance between the stock and barrel when the rifle is supported from a tripod or bipod.
Quick, Straightforward Installation
SRA's drill-guide-assisted mounting system takes the guesswork out of installation. The supplied front and rear drill guides make locating and accurately drilling the mounting holes simple and easy. All required mounting hardware is included. Installation typically takes about five minutes and requires no gunsmithing or special skills
Installation
Basic Installation Step Summary
Remove the barreled action from the factory stock. Use the supplied front and rear drill guides to accurately locate and drill the mounting holes. Secure the G2SA to the stock using the supplied hardware. Reinstall the barreled action in the stock. Typical installation time is approximately five minutes.
Frequently Asked Questions
Does the G2SA fit Ruger American Ranch and Predator models?
Yes. The G2SA fits Ruger American Gen 2 short-action Standard, Ranch and Predator rifles equipped with the compatible factory stock. If you are unsure whether your rifle is a short action, measure the action-screw spacing. Compatible short-action rifles measure approximately 4.046 inches center-to-center.
Does installation require drilling the factory stock?
Yes. Installation requires drilling mounting holes in the factory polymer stock. The G2SA includes front and rear drill guides that accurately locate the required holes and a #6 drill bit. The guides take the guesswork out of the process, and installation typically takes about five minutes. No gunsmithing or special skills are required.
Can I still use a sling with the G2SA installed?
Yes. The G2SA includes a sling swivel stud and provides two mounting positions on the rail, allowing you to retain a traditional sling attachment while using the Arca rail.
Will the G2SA fit a Ruger American Gen 1 rifle?
The G2SA may fit certain Ruger American Gen 1 long-action rifles equipped with the later-style factory stocks manufactured after about 2017. Compatibility depends on the stock's barrel-channel geometry, not simply the rifle generation. If you have a Gen 1 rifle and are unsure whether your stock is compatible, contact SRA before ordering and we can help you verify fitment.
What tripods and bipods are compatible with the G2SA?
The G2SA uses the standard Swiss Arca mounting interface and is compatible with most Arca-compatible tripod heads, clamps and bipod adapters. It allows compatible accessories to be positioned anywhere along the usable length of the rail for greater flexibility in rifle support and balance.
