The A5 is, of course, a long recoil action. The barrel & bolt recoil independent of the stock assembly. When the friction ring is set for heavy loads more friction is applied to the magazine tube, slowing the barrel's movement. This will result in the recoil being transferred simultaneously to the stock. The lower the friction the faster the barrel will recoil & less is transferred to the stock until it Hits the buffer.
Shoot heavier loads than the gun is set up to handle & expect to "Get Your Teeth Rattled" when the bolt rams into the stop buffer.
