The KWA 14mm counterclockwise "Blaze Orange" B-57 flash hider will fit most airsoft rifles, including all KWA AEGs, ERGs, and LM4s. Set screw is included and attached. Please kindly note that removal of your federally mandated Blaze Orange tip will void any existing warranty on your KWA rifle.
The KWA M33 AEG cylinders come in three different configurations, including types 1, 2, and 3. You can find the stock models with their types below:
Type 1: KM4A1, SR10, KM4 RIS, KM16 Battle Rifle, KM4 SR12, KR12, KR14.
Type 2: CQR Mod 1, KM4 Commando, KR9, SR7, CQR Mod 2, KM4 CQB, KR5.
Type 3: No current production model uses the KWA Type 3 cylinder, but it’s perfect as an upgrade for high speed builds where a higher rate of fire is desired. The centrally located port allows a faster piston return, speeding the cycling process.
