Sig Warranty

Just curious about your experience with Sig's warranty. I have a Spear LT 7.6x39 that I keep getting FTF/FTE every 10rds or so. I called Sig and they want me to ship it back to them ($27 cost to me). They're sending me a FedEx label to use and will ship the whole rifle back to me when they're done examining it/fixing it. What was your experience? Thanks!
