Mine is am omega that had a failed weld in the baffle stack. It launched on the very first round. SiCo was good about replacing the internals and it's been good since but it was a bummer. Here's my complete story from another forum. I have put 300-500 rounds through the can in the last year of so and so far everything has been great.
TLDR; Can blew apart, paid to send back, returned a few weeks later.
So after a little over a year I got my SiCo Omega out to the range. Had a catastrophic failure on the first round... Can was Direct Threaded onto HawkHill Barrel cut by Josh over at PVA. I am confident that the threads were true. I ran the can down tight by hand, checked visually (boresight) and verified with cleaning rod. I had good clearance. I wanted to see if I was going to get a POI shift and then check velocity with my Magnetospeed. Had just shot a string of 10 Factory Harnady 6.5 Creedmoors at Mv of 2740 and wanted to see if I picked up any velocity.During first shot I felt a TON of recoil and looked to see most of the can missing. The brake and baffle stack landed about 85 yards down range. It doesn't look like there was any damage to brake or baffles. No sign of baffle strike.
Here's what I could find:
I called SiCo and I explained that it looked like a weld failed and the CS guy gave me a RMA number. I asked about a label and how to ship and was simply told just write RMA on outside of box. I had to call back and ask about how to ship (include tax stamp etc) and ask for their address I shipped it back on my dime and so far I am not impressed with the Omega Hype or SiCo Service.
After a few weeks I got my can back... no real explanation of what went wrong but it was shipped directly back to my house. Ran a few rounds through it and everything seems fine.
