Matt,
The standard thread for a pre-ban AR is 1/2-28 (I think, It's in the DPMS catalog and I don't have mine here now) Some AR barrels are now available with a differant thread pattern and size; these will not accept the dreaded A2 flash suppessor and grenade launcher that can be attached to it(although I don't think any one has actually seen one).
Companies are seelling these as being post-ban legal with a muzzle brake(not a flash suppressor)
