Yes,I have lots of stuff still for the dynamic block. I'm sure I can put you a 500mm together,what caliber? I don't have anymore 156cc plenum for the 30,but if your gun already has the large plenum you'd not need two. I have some 110cc plenums for 22 caliber and 177. Let me knowDo you still have these kits? Looking for a way to change a dynamic compact .177 to 22 or 25.
