The Daniel Defense M4A1 FSP Rail Interface System RIS II is designed to work with Mil-Spec AR15 upper receivers. The Daniel Defense M4A1 FSP Rail Interface System RIS II will work with a Fostech Stryker in .300 Blackout but I recommend using the handguard at the link below if your rifle does not have an A2 front sight gas block.
