Functional, looks cool and quality made. - Radian Weapons Raptor Ambidextrous Charging Handle

This one is good when you have a scope on your AR that sits right on top of of the charging handle so that extra length that sticks out on the sides makes it easier when you lock your bolt to the rear or rack it. It's ambidextrous so that makes it alot more convenient to use too. I think for the price, it's a good charging handle and it makes your AR look pretty cool, plus they are popular and you see them all over instagram feeds.
