Phantom Type Tactical M4 / M16 / Masada Metal Flashhider (14mm Clockwise)

"Does anyone know if this will fit a Dboy/BoyI M4 S-System??? I Don't Know If Dboy/BoyI Flash hiders are all counter clockwise - but anyone with the answer please do tell. Thank You In Advance.

Webmaster: Generally, G&P, Western Arms are 14mm+. The rest are pretty much 14mm-.
(14mm negative = JG, Echo1, Matrix, Marui, G&G, DBOY......ect)
