OK, recently I posted about not being able to install my M510AB on my 20" A2. Talked a bunch with my dealer and directly with SF and found that the M511AB is the light I need, not the 510AB. How I ended up with the wrong light is a long story and SF's fault, but I won't get into that. Unfortunately, SF is not currently making any 511AB's so I'm back to square one and really need help.
Here is the ultimate question: If you could put ANY surefire on a 20" A2 which one would it be and why? I'm open to rail mounted, dedicated forend, anything, I just need to find the right light. I'm a patrol cop and I'm working in the dark with no light on my AR, a situation that I've been trying to change since June, with no luck.
As a side note, would (or have) any of you put a 900 series vertical foregrip light on an A2?
Any suggestions would be greatly appreciated.
Thanks!!
