No, Radian does not offer a model for those AR's.
I would recommend the AR-10 charging handle.
It will match very closely, but will not be exactly the same as the receivers are metal while the levers are polymer coated, so the colors will look just a tiny bit different because of the fact that the materials are different.
The AR15 model Radian Weapons Raptor LT Ambidextrous Charging Handles will be compatible with an AR15 chambered in 7.62x39.
This one will fit on any ar15 and m16 style upper, since 300 black out uses the same upper and lower design, it does not matter
Yes, the radian raptor charging handle is compatible with all ar 15 sized uppers, unless specifically designed or noted
No, you will need an Ar 10 charging handle for that, because these are ar 15 charging handles
Yes, the radian raptor lt ar15/m16 is interchangeable between ar15 upper, and is not dependent on the ar15 caliber
Yes, the Radian Weapons Raptor LT Ambidextrous Charging Handle models MPN:R0151 and MPN:R0153 will be compatible with the Aero M5.
The Radian Weapons Raptor LT Ambidextrous Charging Handle will work with an Aero M5.
