I purchased a rifle from Zach at Ares and it had a really minor leak, 1MPa per day or two. Zach helped me diagnose it, zeroed on on the part affected and sent me a replacement which i've installed and the problem is solved! The entire process only took a few days and I'm back up and running. I wholeheartedly appreciate the fast response and resolution of this issue by Ares Airguns Tactical.
