Here is the new Gen2 Two Piece Free Float AR-15 Hand Guard from Midwest Industries. Free Float handguards are the best way to go for insuring you place the least amount of stress on your barrel but that usually means completely disassembling your upper receiver just to install the rail system.
The Two Piece Free Float from MI requires no gunsmithing to install. No removing of the barrel or front sight. Just cut the delta ring off of the barrel nut. The MI Two Piece Free Float clamps on the the barrel nut which not only makes it rock solid but it hugs it as close as possible to the upper and lower receivers giving it a monolithic look (no gap) top rail.
The Gen2 version looks much cleaner than the Gen1 and now includes 4 QD Attachment points. It is also 2 inches lighter than the previous model. You can order these in either Black, Flat Dark Earth (FDE) or Olive Drab Green (OD). If you are looking for a high quality Free Floating Hand Guard / Rail System without the lengthy installation this is a great option.
