Yeah I'll admit that I have done that once or twice.
However comma I have had zero shift when I was not being a moron as well. I was trying to pick up on a pattern on this but I was unable because I did not shoot it enough.
I don't have a huge amount of experience with the 145 as we only had them for a year before I left my last unit and we use machinegun ACOGs or CQB short dots in my new unit.
What I don't have ANY experience with is the Spectre because again we use S&B's. I would not mind testing them out a bit, but if it has retention issues, I won't bother.
I'd LOVE to trust the fact that because it passed Crane's testing that it must be good kit, but they gave USSOCOM the VLI flashlight with the SOPMOD kit and that thing was a POS!
