Call me a newbie, but I am having problems getting the handguard off of my new AR-15. This mostly has to do with my inexperience (as this is the first time I have even held one). I am trying to get them off for future know how when cleaning/oiling, and I am wanting to replace it with a 4 rail hand guard in the future, so I will eventually need to get them off. The delta ring is very hard to move, and I can't seem to get it down far enough for me to even try to remove the handguard, especially when I try with one hand, or remove a hand to take the handguard off. Maybe I am just weak, who knows.
Does anyone have any tricks or tips? I want to keep the finish in as good of condition as possible, ie.: I don't want to use any makeshift tools that could/will scratch it.
Thanks for your help!
