I've got some Rex Silentium cans on hand as well. Hoping to shoot them this week. They look good. Not the lightest but competitive in weight. They use the 1.375x24 pattern so they will work with most of the industry mounts. Prices are pretty solid, especially if they suppress well.
I've got two more Vox S. These are a solid can at a good price point with no barrel length restrictions, 1.375x24 tpi compatibility and it's lighter than an Omega.
