Ruger 10/22

[Dobetown]

Do all Ruger 10/22's have the v-block barrel attachment or have they been changed to screw in?
Thanks

Even with all the aftermarket receivers of the same design, there's only two I can think of that use a threaded design for bbl attachment. Even those will still allow the slide in fitment of all the common bbls.
