Call of Duty: Black Ops (Nintendo DS)
The M16A1 appears in Call of Duty: Black Ops (Nintendo DS) as one of the five rifles in game. It is fully automatic, and has a 30-round magazine, high power, low recoil, but suffers from poor hip fire accuracy. It has arguably good but a bit obstructive iron sights. The M16A1 is capable of one-shot kills on recruit difficulty, showing its high power. On higher difficulties, the M16A1 becomes a two-shot-kill, though considering that it has a 30-round magazine, it is still extremely powerful. It's usually found with no attachments, though it is possible to find it with a Scope or the M203.
The M16A1 it is one of the pre-unlocked weapons in game, and 150 kills with it will unlock the Scoped M16. 100 headshots with any weapon will unlock the Grenade Launcher for it.
In Zombies, it can be purchased for 2500 points in the second room with no attachments, or in the third room for 7500 points. The scoped version can be found in the Mystery Box. It is the most expensive gun in Zombies. It also has good stopping power as it takes around half a mag to kill one Zombie or three headshots, at lower levels, however it starts losing its power around level 8.
Call of Duty: Black Ops Mobile
The M16A1 is Bennet's default weapon. It cannot be traded for another weapon, except when the player is controlling any other characters or using a mounted weapon. It has very low damage, often taking one magazine to take down one enemy, but has a very quick reload. The player will never run out of ammo, eliminating the need to seek ammunition. It is heavily recommended to fire it either behind cover or running and gunning. When Bennett holds the M16A1, it looks more like a PPSh-41.
Call of Duty: Black Ops II
- "Fully automatic assault rifle. Effective at medium to long range."
- — Campaign description
The Colt M16A1 can be purchased for 1200 points in the tunnel between the Bus Depot and the Diner in TranZit, on the second floor of the yellow house in Nuketown Zombies, next to the initial Mystery Box (first room in the kitchen area of the upside down hotels) in Die Rise, and on the exterior of the Saloon in Buried. It functions almost identically to the M16 in Call of Duty: Black Ops, retaining its three-round burst fire mode and outputting around the same amount of damage per shot as before. However, it has a slower rate of fire than its predecessor, so Double Tap Root Beer is beneficial increase of fire rate and damage, at the cost of increased recoil, thus making it a useful weapon even for later rounds.
When Pack-a-Punched, it once again becomes the Skullcrusher, which will always come with an M203 Grenade Launcher attachment. Like all the non-2025 weapons, it cannot be Pack-a-Punched more than once.

Call of Duty Black Ops: Cold War
The rifle returns in Call of Duty: Black Ops Cold War as the M16a1, and appears exclusively in the campaign. It is the primary weapon for US Troops during the 1968 flashback missions "Fracture Jaw" and "Break on Through", and is used by CIA agents in "End of the Line", "The Final Countdown" and "Ashes to Ashes". Compared to the M16, the M16a1 is fully-automatic, but tapping the trigger will sometimes cause the M16a1 to fire in a burst of 3 shots, instead of the usual 1 shot when tap-firing other automatic rifles.
