There's always more than one way to skin a cat..... When I fixed mine I built up the worn lug by adding some carbon fibre (as it's hard wearing, light and strong) to the top of it. The red arrow points to where I built it up, that's where the wear was so I decided on a direct replacement there rather than adjusting the geometry of the arm's movement. The original design is pretty good but it should have had a hardened steel sear there instead of using a metal with the same mechanical properties as 'chewing gum', even if the parts had simply been made from steel in the first place the problem would never have arisen at all. Looks like that repair has now failed as it's full auto and there's nothing stuck on the bar. Fortunately I'm now well versed in taking it apart!

Well, during my ownership of the gun it worked faultlessly after I repaired it about 3-4 years ago. But like you stated, at least you know how to fix it now and can get the gun back to a full working condition.
