A Brugger and Thomet compact stalking moderator. It would have been here quicker but they needed to check with B&T that its fine for .311 bullets. I now have 3 rifles to take in for moderating from 7 x 57 to 7.65 x 53 with a 7.62 x 39 in there. one mod fits all 3. Its allegedly good for 10 000 rounds before cleaning and although its not user strippable it goes back for a service then. Lightweight, yes especially when compared to a T8 or similar, compact definitely and price wise even without my dealer discount its very competitive. It also comes with a gay little webbing pouch! Its not very big, I only have little hands A variation is required and these now are serial numbered sadly but no problem for me!
