  The Cadex three rail replaces the original M249 hand guard. It provides the operator with a multi rail system for weapon accessories but still allows for quick barrel changes.
• M4 butt adaptor replaces the fixed butt stock with a collapsible M4 stock.
• This allows for a more compact weapon and is easily adjustable for use with body armor.
