I have an Ares M4 SIR and the bolt catch broke. I emailed ares and they didn't respond for three weeks. So I send a follow up email and they respond in 2 days saying that they were having server issues but they would forward to customer service. Then no response for 9 days, so I followed up again this week. If I don't hear back in another week I will try contacting them by name. Thanks for the info.
