I think this is probably the best airsoft flash hider I’ve ever seen. It’s certainly the nicest and most well made.
Unsurprisingly it’s from HAO and while it’s not cheap it is excellent.
It’s a replica of SureFire’s SF4P-556-1/2-28, which is the four-pronged version. HAO also offers the 3P with three prongs.
This one is in the RS spec thread: 1/2-28 RH, which is an option on HAO’s steel barrels. They also make a more widely compatible 14mm CCW.
I love the fake pin hole detail, but that’s what these guys are all about.
HAO is fast becoming the highest-end choice for PTW users.
