Key Features
1️⃣ Quick-Release Chassis
Unlike conventional 10/22 chassis kits that require complete disassembly for maintenance, the SRUNA-22 features a quick-release design. This allows for fast bolt access and firearm cleaning within seconds. Due to the unique design, reassembly does not require re-zeroing the optics.
Additionally, it enables quick swapping of different trigger weights and lower receiver modifications.
2️⃣ Trigger Linkage System
The SRUNA-22 utilizes a dual-link pivot lever system for the trigger linkage. This design ensures a zero-delay, frictionless trigger pull, preserving the crisp, tactile feedback of the original Ruger 10/22 trigger. Unlike traditional bullpup conversions, the SRUNA-22 eliminates the common spongy or mushy trigger feel associated with bullpup designs.
3️⃣ Rigid Chassis for Enhanced Accuracy
The integrated CNC aluminum suspended upper handguard securely clamps the 10/22 receiver and barrel, reinforced with six-directional adjustment screws. This creates an independent sighting assembly, isolated from the lower frame and trigger linkage, ensuring consistent accuracy and ballistic stability.
4️⃣ Left-Handed Shooter Friendly
The SRUNA 22 chassis includes a pre-cut left-side ejection port, making it compatible with third-party left-eject 10/22 receivers—an essential feature for left-handed shooters who wish to use a bullpup conversion.
5️⃣ High Compatibility with Aftermarket Parts
The SRUNA 22 supports a wide range of third-party 10/22 components, including:
✔ CNC-milled aftermarket receivers
✔ Binary trigger sets
Additionally, the forward fire control group is compatible with:
✔ AR-15-style grips, safety selectors, and trigger components
✔ MIL-STD Picatinny rail and M-LOK slots for optics and accessories
