Coming from a guy who has 50+ Airsoft guns I would recommend keeping airsoft with airsoft and getting real parts for real guns.
However the “Raptor Style” charging handles you speak of are in fact made by TrueNorthArms as their Buterfly Ambi charging handles. There is no confusion on where the design came from. My brother bought one for a build and has had no issues with it. I much prefer the “brand name” parts all though my wife does not
Just want to point out that there are alternatives to the pricey brands that offer affordable options to shooters. It does not mean they are airsoft parts. Is the quality the same? No! As I have compared them (wings are thinner/no spiral roll pin). Do they work ok for half the price? Yes!
