I thought that I had my ducks in a row, when I ordered a Primary weapon Systems Diablo with a 7" barrel and chambered in 7.62x 39. My intent was to order a suppressor for it, end up with a barrel/suppressor combined length less than 16 inches and still be able to shoot cheap surplus ammo. Now, I am told that the unburnt powder will damage the baffles and bullet stabalization might be a problem. Anyone have any ideas about how I might rescue this situation?
