 The Pattern 2 Drors had many changes from the first one by adapting to a rimless round and the use of modified 20-round BAR LMG magazines to balance the weapon.In addition, the barrel release was now located at the front barrel bearing with a heat shield, which is colored orange/brown, that can be removed without the need of using protective gloves.A folding cover is also mounted over the magazine well so that the gunner can close it to prevent dirt and other foul elements from going inside when the weapon is not used.
