Why i got this item - AT3 Tactical CH-05 Charging Handle with Extended Latch

After mounting a scope, the latch on the handle was difficult to grasp and pull. I was going to replace the latch alone, but saw it was not much more for the complete handle with the extended latch. I went with this item because it was made of 7075 T6 aluminum. If you look up the difference between this and the 6061 T6... there is a lot of differences. Enough to make a difference in the durability and longevity? I believe so... but that is only based on the physical differences in the two alloys what others have said. I have installed it but have only cycled the bolt to test it. It functions well... no problem cycling the bolt with the rifle shouldered. The lever may look large but I would not want it any smaller. I do notice pulling on one side of the handle puts an uneven pressure on the right side of the slide. Long term effect will be more wear that usual. I did a modification to this handle.... I drilled a small hole in the right side and used UHMWPE cord and a silicone tube and made a pull cord that stretches from the latch side to the right side.. I rests just below the scope and is easy to pull directly back.
