they are cool functional little guns , I worked one over for a friend on an ATF form 1 , we cut the barrel back and built a suppressor for it then pinned and welded the suppressor to the barrl so that the OAL was still 16.5" , now the gun runs as good as ever but suppressed so with sub sonic ammo you can shoot it in your back yard and the neighbors will never know.
I had concerns about doing that much work and putting that much money into what I figured was an "dissposable" weapon , not anymore.
the only trouble I'd see with it is the ammo cost , their so damn fun to shoot that the ammo bill will mount very fast. Its hard to beat a good 22 long rifle for family fun and plinking , you can shoot all day for $20
I'd get a Ruger 10-22 and slowly make mods to it , you can trick one out and realy make a "cool" gun thats very reliable , safe and fun to shoot
