- The words "M79 SAW OFF" and the manufacturer logo can be seen on the weapon's barrel.
- In earlier releases of M79 Saw off can hold up to 10 shells, this was later reduced to 5.
- This weapon shares the same launcher crosshair with the SVDEX's secondary mode and M32 MGL.
- In real-life, the grenade will not explode if the shooter fires it at close distances.
- The M79 is the first break-action weapon introduced in the game.
- In the game, M79's reload animation is not really a reload animation but it is merely a "delay animation", since the animation isn't repeated if switched out and then switched back in.
- This is the first weapon which doesn't show the user reloading animation in third-person view. The second one is the Black Dragon Cannon.
- This weapon deals high knockback when used with some melee weapon's bugs, however keep in mind the ban risk.
