Hmm.... I'm assuming mine does. Currently I have the 416D selector in mine. I've been looking for a nice ambi selector for a while now, but I'm not sure exactly how I want to go about that. Part of me wants to get the A5 kit to add more HK parts to my setup, but part of me is thinking about getting one as part of a bundle with the Raptor charging handle.Should fit those that take a roll pin. GGW only showing to have RAL 8000 in stock.
