Blue Ridge Arsenal They sold me a Adcor BEAR gas piston AR-15, and delivered a gas impingement AR-15 instead Chantilly Virginia

 On Dec.19, 2012, I ordered a Adcor gas piston AR-15 over the phone at Blue Ridge Arsenal, they charged my credit card right away. When I recieved the rifle, I had no way of knowing it wasn't a gas piston. After several problems with the rifle, I cotacted Adcor. After week of talking with them, we discoverd after I ordered parts, that in fact I DID NOT have a gas piston rifle, it was a gas impingement rifle instead ! I the contacted Blue Rdge Arsenal to resovle this. They(General Manager) said there was nothing they could do to right the wrong ! After spending $1576.00 I would like to recieve the AR-15 I paid for !
