I recently purchased a 3 lug adapter for my TiRant 9 suppressor and tried it out on my MKE Z5RS. I'm actually pretty blown away at how well it works. I have several other 9mm carbines (RRA, Colt, Tavor, Stribog) that have threaded muzzles that I'd like to change over to use a 3 lug adapter. I do have a couple of questions. What keeps the 3 lug adapter from rotating off just like the suppressor might if it was directly threaded on? Are there any less expensive 3 lug flash hiders or muzzle devices? All that I've seen are well over $100.
