Neither are needed for most range plinking bla bla bla . I'm of the thought why not have them . They do nothing to hurt your ability to use the gun and in some cases could really help . It's kinda like those guys that say having night sights on a pistol is a waist . I will not get in to all the reasons why it would not be necessary . If it,s not hurting your day today use of the gun why not have them for that off chance you need them . You never really know when your going to need these types of things . If you did you would avoid that situation in the first place therefore you would not need them .
