I just went through this. I upgrade my side panels to Midwest industries mlok ones with a built in QD cup, mounted an aluminum 7 slot rail and then when installed a Haley Stratrgic model Inforce light at 9 o?clock. I haven?t shot it yet but I can see that due to the short fore end, there isn?t much room for my hand. Overall, I think this will likely be an issue for most unless you go with a 10-2 location and tape switch. I might have to look at offset mounts and a different light.
If you google it, you?ll see far more images than this forum will provide.
