This charging handle did not fit my benelli m4 ext - Taran Tactical Innovations Benelli M1/M4 Ultimate Charging Handle

I like the larger handle and the texture was nice. Unfortunately, this would not seat far enough into the bolt carrier to allow the detent to lock it in place. When compared to the stock handle, the detent hole was closer to the shoulder of the Taran versus the factory handle. It would not seat properly and engage the detent in any position. Pretty disappointed, especially from Taran. My M4 is the new EXT version. I would not recommend until you try it in your weapon first.
