WS spec calls it a light duty, slow rate of fire suppressor. An Omega 300 would be a full auto rated to 300wm, neither are serviceable about the same price (not rimfire friendly).
I just got a Jolene 7.62, and my buddy just got a ptr vent 1, and the other got a liberty precision Mach-l. Very happy with it compared to my old recce 7.
