Because the 16" rifle has a railed gas block you will have to remove it to get the old handguard off. You will also have to remove the muzzle brake and I think replace the barrel nut. You will need an upper receiver action block, a bench vise, a barrel nut wrench, an open end wrench for the brake and a strap wrench to loosen/tighten the handguards. A torque wrench to use when you put the new barrel nut on is handy but not absolutely necessary. Watch the videos from Midway USA and Brownells on how to install a free float handguard. It is a simple process and once you have everything in place the job will take maybe 15 minutes. If you don't want to go the replacement route you can solve the cold hands problem with a neoprene sleeve made for either a scope or a Maglite. Of course you have already bought the handguard so you might as well take the plunge. The rest of the tools you will need will cost you under $100 at Midway or Brownells or on fleabay and they will be a permanent addition to your inventory. If you are putting everything back just the same with the exception of the handguard you don't need to tap out the gas tube roll pin and remove the gas tube from the block; just slide the whole thing off and back on being careful not to bend the tube.
My Daddy was wrong when he said: "When a man turns 60 he ought to be able to trade his testicles in on a new set of teeth." Oatmeal and soup don't sound too bad.
