Please help! I am replacing the front handguard on my 450. I have removed the free floater fron my rifle and headed to the gun shop for a replacement. I had to replace the gas block (w/a dpms low profile one) for clearence, because i want to install a mid/rife length hand guard. I was told that the 223 rails would not fit. So i found a ar10 one finally. it arrived,.......too big! and wrong threads,............ok! so what will work? do i need to replace the threaded portion of this??? any help?
