This is an excellent part to fix a broken welded ejector on a Mk2 or Mk5 Sten. Countersunk hole on the backside of the ejector may need refilled and tapped to 2BA.
Original item in used condition. May require fitting due to retainer screw not threading into the countersunk hole on the backside of the ejector.
This part is both the ejector commonly used on the Mk1, Mk2, and Mk2; and as the magazine catch retainer.
