I used a rental airsoft gun, AGM HK416 I think. Now I have either a JG or Tokyo Marui M4 with rails and a barrel extension. No battery for the latter though D:
(I bought the gun from the site moderator, idk if it's one airsoft gun or many x3)
I gotta get back to it my self, lota places closed up around here that I use to go to my favorite one was an indoors SWAT v Terrorist one they closed up
