Broke within two mags - Armaspec AR-15/AR-10 Stealth Recoil Spring

Order a Gen3 SRS for an AR build I had. I put 2 mags worth of ammo through the weapon and then noticed a rattling sound. After tearing the rifle down I found that the wire lock(looks like a piece of flat wire spring) had come off and the entire buffer assembly was no longer being held together I contacted armaspec as they offer a warranty. They offered to replace the part and then went radio silent. No replace part not return address to send them the part. And this is after 5 emails. Very disappointed. I will not own anything armaspec now due to the very poor customer service
