I got mine a couple of days ago , took the f@@@er apart like the manual says had to put the rubber hose bushing back on with lots of gun oil and forced it down with a stick . I have put about 500 rounds through it so far , a couple of failure to feed (I wonder if this is the ammo , mag , etc... ) and a couple of duds (firing pin hit casing but looks light at times ) . Overall very happy , by the way I am using Walmart ammo 333 box of Winchester .
Now this rubber hose , has anybody fired without it yet as I am taking out golf balls at 50 yards and can group within 1/2" when I really try on sand bags at 50 yards . I really want to know so when I take it apart the next time I can throw it away .
