Will this work on a 7.62x39

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on August 17, 2022

The Radical Firearms SpitFire Muzzle Brake is not compatible with 7.62x39 due to the incorrect thread pitch and bore diameter not being large enough to accommodate 7.62x39.

Will the Radical Firearms Spitfire 5.56 Muzzle Device, Black, SF556 work on a 330 Blackout?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on July 07, 2022

No. 300 Blackout has a much larger bullet diameter than 5.56. You would need a muzzle device with the same thread pitch as your rifle/pistol and accommodates 30 cal.
