Well after many phone calls with the store manager then the gun manager and then the lead gun salesman we all finally came to a solution, that is to treat the customer RIGHT. They agreed to take the gun back for full credit, so i decided to just get another m&p 15-22. the new one is of the DSX lot and the instructions do have a red stamp on it and on page 9 the recomended ammo is listed, also the extractor looks to be installed very solid and last the ejector is indeed in the correct location, but sadly no blue springs.Whenever weather and time permits i will give a range report.pghrich
