Ruger 10/22s have always been excellent suppressor hosts. Until recently, if you wanted to use a 10/22 as a suppressor host you had to purchase an aftermarket threaded barrel. This adds cost to an already expensive project.
Now, with the introduction of the new 10/22 Tactical, shooters have access to an off the shelf suppressor ready rifle. The 10/22 has all the great features that you have come to expect from the standard 10/22 with the addition of a threaded muzzle. The rifle will come equipped with a Mini-14 style flash suppressor to protect the threads (there is almost no real use for a flash suppressor on a .22LR chambered rifle).
I commend Ruger for supporting suppressor users like this.
