The SilencerCo Specwar 7.62 is a great sounding suppressor. Long and heavy though.
The Omega from SiCo sounds as good or better but is shorter and lighter. The Omega will cost more.
The Rugged Surge sounds good, and you can set it up longer and quieter or shorter, lighter and a little louder. It is heavy and long in the full configuration but not bad in the shorter configuration.
I didn't like the Dead Air Sandman L, which is long, heavy and has a less than pleasant pitch. But the shorter, lighter but slightly louder Sandman S has a pleasing tone.
The YHM ULT is light, not too long and offers good suppression.
I own two Omegas and one ULT, and I have first hand experience with the others I mention.
If costs are important but length and weight aren't big issues for you the Specwar would be a great choice. The Saker too, though I have no first hand experience with the Saker. If weight and length are important and your barrel is 16"+ and a 6.8 or 308 SBR aren't in your future the Omega would be a fantastic choice, for more money. If a 6.8 or 308 SBR are in your future and length and weight are important than the YHM is a great choice for a little more than the Omega.
The Surge and Sandman S would be fine choices, but I think they run more $'s than the other options.
Since you have to pay the stamp and live with your suppressor "forever," I would wait the extra time to get the right suppressor if a local or at least I state dealer didn't have what you want in stock.
If you are currently using a brake, get rid of it and go with a flash hider. It will make your landowner happier I think.
