I have a Strike Industries extended latch 7075-T6 charging handle. It runs smoother than the unmarked standard CH I had before and I like the extended latch. However I've just discovered the poor reputation SI has on this forum. I guess a charging handle seemed like a simple enough item so I didn't think to check before buying it. Is there anything known wrong with this one specific product? I won't be buying more from SI but I like this one better than what I had.
