1:add a light chunk to ur weapon with glitchy's chunk adder
2:open up insolence and go to the weapon
3:change to the dev ifp and then go to attachments
4:go to chunk #1 (0 is the muzzle) and replace the dependency with the 1fp
5:go to the values and change all of them to "ready"
if u want the laser then u gotta change the light and move it. im still workin on that part
(ive only checked it on the br so if it dont work on other weapons then u at least have an idea)
