Look & build well but... - Seekins Precision DNA Charging Handle

This is an OK product that build good and look good too. My issue with this charging handle is that it's very gritty on the pull back and favors one side. On release, it doesn't alway go into full battery. When replacing with a stock charging handle these problems are gone. So the issue is the product. Most likely due to the cuts down the length makes edges that dig in a bit when using. I wouldn't trust it.
