I read on another forum where a guy lost the bipod rail so he drilled all the way through and locited a nut on the screws for the new rail. I'm now thinking either a JP Enterprise Modular or a Yankee Hill Smooth Tube. IF I CAN FIND A BCG OR BCG PARTS.THIS IS GETTING INSANE. People who never owned an AR now think they need one at an inflated price. My winter build should have been a summer build when i eas thinking about it.
