I'm finally getting back around to working on my star BM that won't eject correctly. Yes I've already replaced the recoil spring, extractor spring, and extractor. Reading online, people have talked about the ejector. I found in on a parts diagram [https://www.gunpartscorp.com/gun-manufacturer/star/bm-star #39] but I can't seem to find it on the actual gun?! Can anyone post a pic showing me exactly what I'm looking for?
