I have a Bushmaster C15 Superlight on the way and could only find 1 single gas block with a top rail anywhere (because its a .625 barrel) and paid almost triple for a Doublestar gas block only to find out it might not work on my rifle. I guess there's 2 different styles? The double star uses a set screw i believe. The item hasnt shipped yet and id like to cancel before it does if its the wrong one. Does ANYONE know if this gas block is compatible with my new BM? If anyone can help, you're a lifesaver.
Thanks!
