I am planning on de-chroming the ejector rod using my lathe and some emery paper prior to blueing it. As part of this I might machine a dimple on the end to give a bit more location at the front, not that it is bad on mine anyway. I have noticed that the sprung loaded plunger under the barrel only just touches the end of the rod, so can't be doing much anyway! So that will get some attention too... Picked up my 6½" BB version today and although the cylinder is much less wobbly on the crane there isn't a spring behind the plunger! Still got the pellet version and comparing the 2 the barrel forcing cone spring is stronger on the BB version. Really hoping it shoots as well as the BB 629. |

Hmmm, must take a closer look at that, I thought there was a spring in there!

I know it might be difficult to believe, but it could be a quality control issue...   |

Managed to put some lead through it today. Couldn't match the 1 hole groups of the BB 629 but it definitely shoots pellets better than the pellet version. Can't really complain for free can I?

Looks like just pushing the pin out will allow it to come out I got a chance to check mine today, the little 3" has a sprung plunger but the 6½" hasn't....FFS ! Modski66 is right, definitely a QC issue with these guns. I'm not sending mine back again though, I'll pop the plunger out of the 3" and measure the spring, then I'll order or make a replacement one for the 6½" version. Shouldn't have to do this with a new gun but I'm beginning to think that everyone of them has a fault somewhere or other if you look closely enough. I'm at a loss to explain it though as the S&W 629s are absolutely perfect ! |

It doesn't seem to make much difference as it is, but I was thinking of doing Mark's idea of countersinking the face of the ejector rod. Think I'll probably nick the spring from the review one and put it in mine! If someone wants to do a trial run on theirs so I know what to expect it would be appreciated! |

I thought about countersinking the pin on mine before I decided to return it but I don’t think it would be that simple. You’d have to have a bit of a ‘ramp’ on the outside of the ejector rod so it didn’t just try to push the sprung pin sideways when closing and I don’t think there would be enough room for a ramp on the outside and a dimple in the middle.
That’s when I started thinking about bonding a small steel block on the crane arm to lock onto a tiny magnet recessed into the frame.

Just checked the 6.5 inch model I bought from James, it definitely has a spring in there.
I got to thinking about the dimple idea for the ejector rod, and it needing a ramp on the outside, but it manages to close fine now without one, so a dimple in the middle won't make any difference.
Liking the magnet idea though!

The magnet idea would be pretty simple to do - bond a shaped piece of steel into the void on the back of the crane arm and just dab a 6.5mm end mill onto the corresponding section of the frame (behind the closed crane arm) to make enough of a hole to flush mount a 6mm x 2mm micro neodymium magnet, which would be epoxied in place. That would really tighten the front end up and could look factory if you took a bit of time on it. Now all I need to do is sell my Magno-latch™ cylinder lock-up system to Umarex!  |

It's too late, you have placed the idea in the public domain! The only thing you could claim is 'prior art' as it is is recorded on here, but you probably wouldn't get owt from Umarex...  |

Is it on the ejection arm. |

It is in the barrel shroud, directly in front of the ejector rod, there is a black plunger that is retained with a cross-pin.
