I Have a little issue . Broken the left arm on my New Eye Jacket FMJ 45mm . I am trying to source a replacement arm for this . I am in the UK . There is a set on ebay currently for the New Eye Jacket 5.56 . Are the 5.56 the same colour as they are FMJ too or am I missing something . I cannot see a difference but just need some Eye Jacket expert help please . Thanks
