After having searched the net, I'm finding waay too much information on forearms for ARs. I'm considering building an extremely lightweight AR (carbine) and am looking for an 8" to 10" (preferably 8") lightweight forearm with the capability of attaching probably only one accessory at the muzzle end (flashlight, red dot, etc.). When I search the internet, I find some for $35 (+/-) and some for $350! I really don't think I need to spend $350 for my project. Any recommendations ons? What to get, what to avoid???
