Thanks for all your reply guys. I was thinking about mounting the G&G ACOG (http://www.mtmfg.ca/product/gg-acog-...shair-1812.cfm
) for either the G&G GR16 R4 Carbine or the ICS A1 RIS. Im not sure if it will fit on the top RIS of the gun and whether the front site will block the crosshair of the scope.
Ive seen many pictures online and if u look at the gun from a sideview, the height of the front site is as high as the middle of the scope. When I look through the ACOG/RDS scope, will I be able to see the front site at no magnification and with magnication?
Is it actually better to mount the scope directly on the rail or on the carrier handle?
Thanks for your help once again
