Details/Drawings for AR15 and AR10 handguards?
I'm interested in possibly trying to machine my own handguard (free floating) as a goofy hobby project. I have my lathe and a converted bridgeport CNC, so I'm looking for mechanical drawings on what the interface to the barrel nuts look like on an AR10 or AR15.
You can download a complete set of drawings to make an AR-15. This would describe the barrel nut to secure the barrel into the receiver.
The handguard interface(s) are proprietary. The ones I have both use an indexing pin to ensure the slot for the handstop remains at the bottom. Sometimes there are multiple points for the pin to index into. This allows the user to rotate the handguard and the hand stop to accomodate shoting with a cant.
