I see. i am going for a different look with the hand-guard something with better venting. i also want to be able to put a fore grip attached to the hand-guard and as well as a flip down front sight. What special tools will i need to have?
Looking to change the hand-guard on the Sport II, the model sport 2 i got came with the red dot so there is no front sight, anyone else swap the front hand-guard out and can post a link to one that will work. also will i need a new gas block?
