Real Steel M16 triangle handguards to go with the RS flat sided slip ring
Stock is a nylon fiber G&P M16A1 WA GBBR mounted on a King Arms aluminum M16A2 AEG full stock tube(minus the extension). Not an exact fit with the AEG lower receiver dimensions, but it's not too noticeable. The trap door allows access for the battery, though the size of the compartment is a little smaller then the original ABS stock. I had to do some shimming where the stock recesses into the receiver, but nothing permanent as I might put it on a GBBR down the road. All in all it feels a lot more solid then it did before.
Now if only it had a steel outer barrel and front sight block......
