Couldn't load pickup availability
This rail is basically just a shortened version of our full length G2SA arca rail and measures in at only 4.5”. Mounting this rail is just as fast and easy as its big brother and includes a replacement front action screw which is used as the rear attachment point for the rail.
Like all our rail products, the H-G2SA Arca Rail is manufactured in-house in the USA from high quality aircraft grade 6061 T6 aluminum.
Compatibility:
Unlike the competitors “universal fit” rails, the H-G2SA Half Arca Rail has been meticulously engineered to precisely fit the 2nd Generation Ruger American short action rifle stocks but will also fit most late-model (post 2017) Gen 1 stocks.

Key Features:
-
Fast and Easy DIY Installation: Comes with drill guides and premium hardware—and can be fully installed in just minutes.
-
Perfect Fit: Using 3D scanning technology to guide our CAD modeling, our rails are contoured/saddled to perfectly fit the factory rifle stock, resulting in a precise and ultra-ridged mounting solution.
-
Weighs Just 2 Ounces: The rail is skeletonized in a strategic geometric pattern to reduce weight while maintaining superior rigidity.
-
Enhanced Stock Rigidity: Significantly stiffens the factory Ruger stock, reducing fore end flex, improving accuracy and consistency.
-
Compatible with all Common Swiss Arca Mounting Heads and Accessories: Full-length Arca rail for easy attachment of tripods, bipods, and other accessories.
-
Built for Performance and Durability: Machined from aircraft-grade aluminum and finished with durable H-190 Cerakote to withstand even the harshest conditions.
