These Phantom flash hiders are threaded 1/2 x 28 RH. Ideal for your AR15 or AK47/74. Extended Length (adds approx 1/2" to your standard Phantom). Has WRENCH slots (no detents). Slightly longer than standard length AR15 Phantom flash hiders, Measures 2.4" These will work amazingly well on your AK47 rifle. Made in the USA.
This will also work on Saiga 308, 7.62, 223 and 5.45 if you thread the barrel to 1/2 x 28 RH.
I bought this for use on an AKV. I bored it out to pass a 9mm round at .355, as it would not. It wasn't designed to. Part was as expected, with even finish and no machine or tool marks. I appreciate that the price was reasonable, and don't see how some companies are charging close to $100 or more for a flash hider.
