Sig 556 H style flash suppressor

[pat701]

I just ordered a Sig 556 Patrol rifle. It comes with a H style flash suppressor. I looked all over the INTERNET for information as to what an H style suppressor is and can't find anything. Will some please explain what a H style flash suppressor is?

from what i could tell it's the A2 birdcage type flash suppressor which comes on every military m16/m4 or civilian market ar15's there very common nothing special and easily replaced with better ones for pretty cheap just make sure if you buy a new one it matches the thread pattern and check to see if it is right or left hand threaded

The Sig 556PR uses a "bird cage" style muzzle devise. It's 1/2X28 RH thread. 1/2X28 is standard for the AR in 5.56.
