Decent blend, looks great, loud but not crazy and it's not quite as distracting to be next to as a miculek.
If you want premium accuracy from the build, try something else, if maximum precision is not a priority but recoil control is, go for it. I'm pretty happy with how it keeps the muzzle steady under repeated shots. I'm honestly not sure it's any better than the much cheaper YHM Aggressive End comp, my buddy has one on his rifle and we honestly can't tell the difference in noise, recoil or blast, but we agree that mine wins on style.
The accuracy thing is because it's one of the comps known to effect accuracy. I'm not sure if anyone's done a real scientific test, but I've heard it from a number of folks using them and not using them, and I get that feeling on my own. I just can't take mine off easily to test it due to CT laws.
