I have 4 Lane suppressors (one still in time out) 22, 556, short 30 and scorpion magnum.
http://www.lane-products.com/All are solid titanium, yes they cost more but you only buy them once, you have to live with them forever.
they are the only ones I know of that make an all titanium suppressor, they are amazing to say the least. I have a ruger 22/45 lite with a burris ff3 red dot that I just love, kids have a blast shooting it too.
Recently I looked over a Rebel suppressor at my LGS
https://rebelsilencers.com/They cost considerably less than the Lane, but are a little bigger and not as sleek in design. That said, I was impressed enough with it to give it a chance. I won't get it until spring though I'm guessing.
That NFA tracker has never been right, my wait times are usually a month longer than they estimate at least, sometimes more.
