General Info for Bravo 10/22 Chassis Introducing the 10/22 Bravo Chassis. Designed to fit your favorite Ruger 10/22 for that dream build you've always wanted. Featuring the same great ergos as the standard Bravo but with a slightly shorter minimal LOP (~11") for shooters of all sizes. For those of you over thinkers out there, don't worry, the cheek piece position is still the same as our standard Bravo. The 10/22 Bravo ships standard with a .75" spacer, so for anything over a 11.25-12" LOP you will need to add the 10/22 LOP Extension Kit. The Bravo is one of the most comfortable stocks available but that's just the beginning.The Mfg: Kinetic Research Group
