Poor quality control - Sharps Rifle Company Xtreme Performance Bolt XPB Carrier Group (BCG)

Bought this thinking I was getting a high end bolt carrier group. So I took it to the range too test it out and all I got was a click and no bang. After taking it apart to trouble shoot the problem I found out the firing pin was way to short by almost 1/8 of inch. So I called them and emailed them and got no answer or no response. So I paid $229 for the bcg and now I had to buy a firing pin out of my own pocket. That did fix the problem. They have no customer support at all.
