this weekend me and my buddy took the 22 to the range for a little bit cause we got board. at about 250 rnds it stopped firing. i dont know what the part is called that broke, but it has something to do with the trigger i think. i need help identifying it and a website were i could order the new one from. thanks for all the help guys. its the white plastic piece at the back of the reciever. it directly down from the a and n on the screw driver. thanks guys im looking to get this fixed so i can go shooting again!
