I have two Silencerco omegas, one with an end cap and the other with an anchor brake. I don’t really notice much of a difference between them……but I’m also using them on an AR15. On some thing bigger than 556 there might be a noticeable difference.
My man you are really struggling with navigating this forum. This is about firearms and should go in the firearms section. I've reported it already so a mod will be along shortly to move it.
