I own a Romanian SAR-3 AK, chambered in 5.56x45. And yes, it actually has a straight front sight and no trigger slap. I would like to add one of the Phantom AR flash hiders to it. I really have no need for an AK-74 style muzzle break on a 5.56 semi auto rifle. But I do use a lot of Wolf ball ammo in it, and the muzzle flash can be pretty obnoxious with this stuff. Since my rifle actually shares the same 1/2" diameter barrel as an AR, I am thinking about having the muzzle threaded in the traditional AR pattern, rather than the AK style thread. Then, using AR muzzle devices with the AR style washer-rather than the AK style spring loaded detent. Any thoughts on this? Has anyone tried anything similar?
