I have the Turbo K and love it. I put it on my 10.5" AR-15 and was surprised at how quiet it was. For shooting standard .223 rounds I could comfortably shoot it without hearing protection. When I shot my .30 cal suppressor of a different brand on that same AR it was considerably louder. I had done a lot of research on the Turbo K before I purchased it and it compares very well to other suppressors and for the price is an excellent value. I don't remember why I went with that over the T2, probably because the K is newer and very close in DB rating but shorter and lighter if I remember correctly.
