i purchased an upper for an ar15 from rguns on 8-2-13 when i took it to the range it faild to work properly i sent it back on the 20th for warranty work. on the 27th after a great deal of abuse they sent it back. now ti works even worse than it did when i sent it in, now they refuse to honor thier warranty. i will never do business with them again.
