I'll explain in detail as much as I can, With certain sights (Including Backup RDS) The reticle does not appear until I shake the gun wildly and rapidly, it's as if there is an invisible square blocking the centre of it, the sights that do work is the iron sight, ACOG, The Third EOtech sight and the Futuristic sight.I am guessing this is an addon conflict. I am wondering if anyone else has this Issue...
