Sb22 Fixed Kit: Features & Specifications
The SB Tactical Sb22 Fixed Kit transforms your standard Ruger 22 Charger into a highly modular platform. Built in partnership with Unity Tactical, this chassis uses a reinforced polymer body wrapped around an aerospace-grade aluminum insert. This gives you a rigid mounting surface without adding unnecessary weight to your pack gun.
At Atomic Defense, we recommend this kit for anyone looking to modernize thier 10/22 fixed platform. The integrated ambidextrous steel QD socket means sling management is built right in, and the flat top cover provides plenty of rail space for your primary optic.
Key Features
- Lightweight Build: Polymer chassis with a solid aluminum insert for maximum durability.
- Rear Attachment: Picatinny (M1913) rear rail for easy installation of braces and stocks.
- Sling Ready: Integral, ambidextrous steel QD sling socket.
- Grip Compatibility: Accepts standard AR-15 pistol grips.
- Bridge Mount: Includes Picatinny (M1913) Bridge Mount and Flat Top Cover.

Sb22 Fixed Kit: Frequently Asked Questions
Sb22 Fixed Kit Vs 10/22 Takedown Chassis: What Is The Difference?
The main difference comes down to your firearm's receiver type. The Sb22 Fixed Kit is designed strictly for fixed-barrel versions of the Ruger 22 Charger and 10/22. If you have a Takedown model, you need the SB22 Takedown Kit, which includes a separate M-LOK compatible handguard to accommodate the barrel removal mechanism.
Does The Sb22 Fixed Kit Include A Brace?
No. The kit includes the chassis, bridge mount, flat top cover, and a Reptilia CQG grip. You will need to purchase an M1913-compatible brace or stock seperately to complete your build. The firearm and other accessories shown in product photos are also not included.
