I have one. Its accurate, if i recall its an oddball twist too. 1:30 or something? May be mis remembering.
USed 240gn xtp with green sabot and it was a good shooter.
worst parts: the sites on the stock barrel are sub par. Barely adjustable on mine, which was an early edition.
If you dont clean it ASAP you might as well buy new bolt/springs/internals. Blowback gets all over inside IME and its annoying. Clean it, scope or peep it, and its a real winner.
Come t think of it, I am going to pull mine out again. Been sleeping for a long while.
