I see that Griffin Armament has a new charging handle...called the SNACH.

Supposedly this has a deeper lip on it, a gas groove, and a gas vent that is supposed to direct gas away from your face when shooting suppressed.

Since my suppressor is in jail still I can't really test it myself, but typically how bad is 'blowback' when shooting with a suppressor?

I am wondering if these charging handles are a must have or not and maybe get people's opinion who shoot suppressed a lot about this kind of product.

On the surface of it it sounds pretty good, but I am wondering if it's worth it to buy one in place of the Raptor I have now.
