I just bought a 2 POS telestock off the form and installed it yesterday. Not thinking I installed it and failed to test function it at all. I went to go shoot at 5am this morning and the bolt wont even pull back. I NEED THIS TO WORK. The rifle is a brand new Bushy and has never been fired. Did I install this thing wrong? Also the buffer has a funny rattle to it. HELP HELP

You most likely had a non tele stock before right? and the new one (tele stock) came with no buffer and spring right? The A2 buffer and spring is to long to fit in a tele stock.
Get a CAR buffer and spring.

It does have the correct buffer and spring.

Remove the buffer and spring. If the bolt goes back , then you have a buffer and spring problem.
