Note the KEY DESIGN DIFFERENCES.  You **** lose.  Answer the **** long rifle question, you lying piece of ****.
M4 v M16

Key Design Differences

• Barrel Length: The M16 features a full-length 20-inch barrel, while the M4 uses a compact 14.5-inch barrel. [1, 2]
• Stock: The M16 has a fixed buttstock, whereas the M4 is equipped with a collapsible/adjustable 6-position buttstock for easier handling in tight spaces and use with body armor. [1, 2]
• Gas System: The M16 uses a rifle-length gas system, while the M4 uses a shorter carbine-length gas system tailored to its shorter barrel. [1, 2]
• Handguard and Rails: Modern M4 variants typically feature a Picatinny rail interface and railed handguards (such as those by Knights Armament Company) for attaching optics, lasers, and grips out of the box, whereas older M16 versions used triangular or round polymer handguards with fixed carry handles. [1, 2]
• M203 Integration: The M4 barrel features a stepped cut to accommodate the M203 grenade launcher, though modern setups often mount launchers directly to the rail system.
