With the release of our dedicated .22 rifle just around the corner(details soon) we wanted to give a sneak peek at one of the features that will be included. Our new patent pending anti-jam charging handle prevents the worst types of malfunctions and make installation of action easier.
A standard charging handle will allow a spent or live round to wedge its way in the channel of a standard charging handle, our new charging handle is shallow to prevent a round from getting lodged. We added of a small center fin that deflects the casing downward before it becomes pinched. This prevents a casing from getting stuck between the spring housing and charging handle. We also added a relief at the rear so charging handle may be fully closed when action is installed into upper. While this version is not for use with the drop in conversion, we will have a variation that will.   Comparison between standard charging handle and new CMMG Dedicated Anti-Jam T-Handle   Small Fin in center prevents spent case from being pinched between spring housing and charging handle    |

Good thinking.
That's a whole lot simpler than my extended recoil rod modification. |

Looks good, I like the fact that people are out there trying to improve the conversion system.

We have lots of other upgrades coming out in the near future. You won't be disappointed, the rimfire world is going to be really really fun!!!!! We haven't set the price on this yet. It will likely retail between $15-20. |

The main problem I have with my Ciener conversion kit is the occasional empty case getting stock between the charging handle and the bolt face.
So put me down for one of these along with your bolt hold open kit and 3 mag conversions. |

So the way I'm reading your original post is that this charging handle only works with dedicated .22 uppers. It won't work with my conversion kit inserted into a normal AR?
I absolutely love my CMMG kits. I had to buy my wife one for her AR. We have put literally 10's of 1,000's of rounds through them. The only jam we have had is the one you describe where a round lodges above the kit in the charging handle. If this fixes that I'm game for 2 handles. Thanks CMMG! |

If a standard charging handle will work with it, this one will work with it. |

If a standard charging handle will work with it, this one will work with it. I'm only going off the picture and my experience with conversions vs. dedicated upper so this may be wrong. Dedicated uppers don't normally have a gas tube. Dedicated upper charging handles don't have the hole in the front for the gas tube. If I'm correct, the charging handle above won't work in a 5.56 upper with a conversion because the charging handle will hit the gas tube. |

That is a great idea CMMG. I will be ordering two of these to replace the charging handle's in my Spikes ST-22.

We will have these available for both dedicated and drop in units. We are toying with a couple different designs for the drop in to give the best anti-jam results. The friggin gas tube is really in the way!!!!

Do you need to design one for the drop in? Doesn't the gas tube create the same effect you are trying to achieve? It seems the problem lies with the standard cut charging handle used in dedicated uppers without the gas tube which allows an empty space for the round to get caught. (You have solved this with the above design/photo). With the drop in and gas tube this space is taken up - doing the same thing. I don't think the round can get caught in one, but didn't go check.
If it can get caught when the .22 bolt moves to the rear (in the CH between the end of the gas tube and the top of the bolt) you could fill that space in the CH. |
