-MadTommy 367 Posted February 11, 2014 I have a pristine 'universal gun flash light'. That is described as a universal light to attach on a gun. I'm unable to attach it to my pristine M4. Do i need a certain 'something' to attach it to? Or is it not compatible. I've attached a pistol light to my fnx45 with no problem. Thanks for any help.
