I asked a posted on sigtalk.com and a member told me that there's a pin that holds the ejector on the bolt. after some research, i used a 1/16 punch and knocked out the damaged crush pin. On November 12, i contacted Sig Customer service about the broken part. and i was told that they will mail it to me. On November 19, i called them again and pointed out i never got a tracking number for the part. The rep told me that it was mailed via USPS and i should have it soon. Well, today, November 27 and nothing from SIG in the mail... May i ask if this is standard operational practice in this industry? Luckily, i ordered a 60cent part + $7 S&H from armalite.com and it arrived in 2days. I do love the SIG716. It shoots everything i feed it. Their customer service? 2 thumbs down...
