No feedback on suppressors but customer service is non-existent. I've had a Solus ordered since November 24. The order is marked "processing" and has been for most of the time. I ordered two bolt faces. One showed up, one has been marked processing for months. The one that showed up is the sized of the bolt marked processing and vice versa. I've used their contact form at least three times and not once did I get a reply. They make good "stuff" but offer nothing in the way of customer service.
