Scored this for $80.00 at a local pawn shop. After a day of cleaning it cycled flawlessly, CCI .40 gr. Knowing it was a decent shooter I went with Warne rings and an inexpensive Vortex Diamondback, HP 2-8 x 32 and sighted in @ 50 yards, CCI 36 gr hp. I've had a few .22's never put a decent scope on any of them or shot them past 50. I've shot this one at 100 and was surprised. Must be this longer barrel and a half way decent scope. Full length tube holds 18.
