Couple of us went out behind his house on the Yellowstone River with two 16oz beer cans, put 'em up on a cord of firewood and blasted away. Loads of fun to fire this little gem. No jams or anything near it. Was using some $5.99 a box ammo made in the Czech Republic that I bought from Center Fire Systems. OEM iron sights were dead on at about 25 yards; but with only one magazine still, my thumb was getting sore!! Up Lula is still in the mail from Israel. One question: Isn't the bolt & operating handle supposed to remain back on the last round fired? Seems it should, but can't even retract it back into a locked-back position.
