First post and question about Bipods

Hello first off .....

So here is the deal I have a JG Bar-10 arriving today that will not stay stock for long that I can promise. I went with the JG since it had decent reviews and I plan on doing some heavy mods to the stock like adjustable butt plate and cheek plate so I didn't want a high investment if it all went south I have seen the videos of the french gentleman that modded his and I plan to steal some of his ideas but not go as far as he did. I plan on foam filling the stock also, but what I'm looking at is making a bipod that folds up into the stock and I have not found anywhere any videos or how-to's if anyone has done it before.

So has anyone seen it done before and if so can you direct me to pictures or links?

Another question has anyone ever foam filled the barrel to provide a very stable point for the inner barrel?
