Have you had any major shifts with your 9mm cans?
I got a Max-11 upper with the SWR Trident 9 can, and its moving the POI up about 5" at 25 yards.
I also noticed it makes a difference how I have the can oriented on the 3 lug adapter.
Withe the log at 6 o'clock, POI shifts about a foot up.
With the logo at 10 o clock, it shifts about 5" up. I haven't yet tried 2 o'clock position.
What are y'all finding
I'll try to figger out a time and set up an appt.
