Things I liked: DO NOT BUY THIS AIR RIFLE...COMPLETE CHINESE CRAP. I DON'T EVER SPEND TIME REVIEWING ANYTHING, BUT THIS IS WORTH THE WARNING. ALL THE SCREWS CAME LOOSE, ON BARREL, AND ON SCOPE AND ON STOCK. AFTER, LOCTITE BLUE ON ALL, STILL ALL CAME LOOSE BECAUSE OF HEAVY RECOIL. CANNOT ZERO SCOPE FOR LONG. TRIGGER IS NOT REALLY ADJUSTABLE, IF YOU TURN TOO FAR, TRIGGER CEASES TO FUNCTION, FEELS LIKE A BROKEN CAP GUN TRIGGER. TONS OF CREEP IN TRIGGER ONCE THE SLACK IT TAKEN IN, THROWS OFF ACCURACY. Let's not forget the significant barrel droop. Also, you will have to refinish the wood, comes with a very dull, dry finish, needs tung oil or wax. Very heavy gun.
Things I would have changed: MAKE A BETTER GUN
What others should know: SAVE YOUR MONEY AND BUY AN R-9 USED. RUGER FAILED. The gun looked great when I bought it, functioned well for a time and then completely fell apart on me.
