Had high hopes... - Superlative Arms AR15 .750in Solid Adjustable Piston System

I had some high hopes for this product after reading some reviews and watching video reviews. However, the piston rod bent the very first time at the range. Adjusted 4.5 turns to fully open, turned 15 more clicks for halfway open on the gas bleed off side for a starting point. Adjusted a few clicks back in until the bolt would catch on an empty mag. Added one more click just to be safe. Shot 60 rounds of cheap Russian ammo at first, some semi and some full auto bursts. Switched to Hornady factory 5.56 55gr Frontier for 60 more rounds. Didn't notice anything different except a higher rate of fire, which is to be expected. No issues at the range once dialed in. Got it home and took it apart for a cleaning, instantly noticed the piston rod was bent in two spots. I've inspected the upper and found no other damage or issues except the rod. Installation was simple and I had no issues with that part. Everything lined up and ran smoothly during functions tests. I've installed tons of gas blocks and some Adams Arms piston systems with zero issues. I work on firearms everyday as my job. The system was definitely installed correctly. They claim they've tested these beyond 10,000 rounds using full auto. Not sure I believe that now.
