I have the silhouette model that is same as you describe, except in blue, and its a very nice rifle . It came with a threaded barrel and the accuracy with heavy bullets(SSS) thru the can is great. I would recommend them to any one who is looking for a accurate cost effective field gun.
I also have a BRNO Mod 1 thats much older but just as neat, 3 leaf sights for 50,75,100 and dead on. It looks like a mini M-70 Win. No trouble chewing a 1" hole at 50yds with most ammo that I've tried with either rifle.
