All the specs should be on the EdGun West site. I'm very happy with mine. Got the 600mm package with shroud. The can is about 6"x2". Most effective moderator system I've used to date on the Leshiy 2. I've been using the STO Sarissa mostly to date and this is bit quieter but a little more pop to the sound where the Sarissa is more of a delayed air whoosh.
Haven't weighed it, but it's all Al and pretty lightweight.
Got my tracking number for my 600mm Behemoth kit on Monday! Hopefully will be here in the next few days; already put my 600 mm barrel back on and got it dialed in. Was using the Huma Mod50 and was happy with the noise reduction but was intrigued by the quick disassembly of the moderator.
