Is this going to cause problems?

If there is a government "Black List" for people to watch our for, I sure hope this post doesn't place me on it.  But I got some new parts for my M4 rifle and I am pretty stoked.  They include a new pistol grip with a storage compartment, new trigger guard, new B.A.D. assembly (which is brilliant--Magpul Tech came up with this device to make the trigger finger able to manipulate the slide lock/release without leaving the grip) and an oversized charging handle.  I think it is all pretty awesome.  Now I just have to figure out how to make these modifications without destroying the gun, myself, or anyone else.
