Morning. I have a RRA 6.8
and when shooting I feel this vibration
in the stock almost if a recoil spring
is "twanging" after each shot-very
annoying".I'm wondering if anyone
else has experience this or is something
in the stock broken? I believe the stock
is the A2 operator stock.It doesn't fold or collapse
Thanks so much

  Good Morning rong,
  
  Is this your first AR-15? Just curious. The recoil buffer spring is located in the stock, inside the buffer tube. So yes, it is quite common, to feel a vibration, and/or hear a twanging.

  If you rub grease on the spring, it will reduce the vibration.

  Yes, this is my first Ar but I
  shot my buddies colt and never heard
  or felt anything.
  What viscosity grease should I use?
  )I bought one of those AR Scopes with the laser
  and lit blue graduated cross hairs.
  Nice if you look at the cross hairs. Very
  soothing cool blue, laser is nice too
  but your target is so obstructed with all
  that crap. It should go on a kids bb gun.
  I know better too, but I guess my childness
  takes over my better judgement when I jump
  into something different
  Thanks so much
