The Gen 2 Spectre Ballistics International Chassis takes the 10/22 platform to the next level. The SBI chassis is CNC machined from solid billet aluminum to the highest standards. The chassis strengthens the 10/22 action improving reliability and accuracy while adding AR carbine stock and grip comparability. The handguard is integrated into the chassis, free-floating the barrel and features M-Lok mounting slots. To securely anchor the action to the chassis SBI developed the Receiver Stiffing System (Spectre RSS). This system uses the rear action pin as a secure anchor point. 

Spectre Receiver Stiffening System

Barrel droop and a flexible receiver have long plagued the Ruger 10/22 platform. Especially when using free floated heavy profile barrels. Attempts have been made to add a rear tang to the 10/22 but this requires milling and permanent modification to the rifle and stock. We have developed a system using the rear take down pin as a secure mounting point. No modification is required and all the hardware is included with the SBI 10/22 chassis.

Free Floated Barrel & M-Lok

A free floated barrel is essential for accuracy and cooling. The Spectre 10/22 Chassis fully free floats any profile barrel. 

M-Lok is the leading standard for mounting accessories. It is used by many military organizations around the world. The SBI Ruger 10/22 chassis is the only one currently on the market which features an M-Lok handguard. There are 4 M-Lok slots on the sides and bottom of the handguard.

Precision 10/22 Chassis

Putting your 10/22 in the Spectre Chassis will not only improve the looks of the rifle but also accuracy, reliability, and ergonomics. The Spectre RSS system stiffens the rifle removing receiver flex. With less flex the action is capable of better accuracy and reliability.
