The M16A4 is the modern evolution of the line — the full-length rifle brought up to date with a flat-top receiver, a removable carry handle and a railed handguard. CYMA's CM009A4 captures it in full metal, pairing a long 20-inch outer barrel for accuracy with a 12-inch quad-rail RIS forend that opens the gun up to optics, grips, lights and lasers.
What's on the outside
Lift off the carry handle (it has its own built-in rear sight) and you've a full-length flat-top rail for a red dot or scope; the 12-inch RIS forend carries 20mm rails at all four positions, while the fixed A2 stock and pistol grip keep the classic feel with sling swivels fitted.

Good to know before you buy
That railed forend is the appeal: a classic full-size platform you can actually kit out with modern optics and accessories. It's the standard full-metal build, so an 8.4V or 9.6V NiMH suits it best, and Tokyo Marui V2 internals mean upgrades are simple down the line.
