These hinges are the basis for our Modular brace and stock systems. There are 3 options for use with various mounting configurations:
- 2-BOLT: these fit all of our standard rear firearm adapters and have the appropriate 2-hole mounting pattern
- A3T Picatinny: this is our hinge for mounting to a standard Picatinny rail
- Sig Picatinny w/A3T adapter: This is a Sig Sauer hinge with our adapter that allows it to work with our Modular components. Use this option if you need downward offset. Please note that this option adds an additional .50" to the overall length.
