I have different grades of ARs (4) and one is a low cost Plum Crazy with a JSE Surplus upper (Under $500 total) and for average shooting it's more than adequate...my goal was to have the least expensive one I could put together...I could upgrade the trigger and barrel, but that would defeat my primary purpose with the rifle..It puts a nice group at 50 yards with military hard ball ammo for plinking..

and produces nice groups with my handloads...

My others have various upgrades and that adds to the overall cost ($800-$1,400)...As stated above, removing the front sight is not a big deal...all of mine have optics of some form...
