Can in the hand yesterday, so, anxious to try some quiet binary time.  Have read recently about some end cap or baffle strikes on Obsidian 9 cans, but it seems to be all, or mostly all handgun issues. I haven't reached the end of the internet search results yet, though. Is it an issue on the MP5/AP5 platform with the tri-lug?  Or the screw-on for that matter? Should I order an alignment rod to check things out before I light the fire?

My AP5-P has perfect alignment with a SiCo 3-lug as well as a Kaw Valley MACH 3-lug on my Omega 9K, Octane 9 and Omega 45K.
