Loading the Line Launcher
1. Use only Mossberg ® approved launcher loads.
2. Keep the muzzle pointed in an upright and safe position. The shaft must
remain in the most rearward position down the barrel. The depth warning
indicator on the shaft should not be visible.
3. Keep the muzzle end up and away from any unintended target. Double
check that the action is open, the safety button is fully rearward in the
“ON” (SAFE) position and that there are no shells in the magazine tube,
chamber, barrel or elevator.
4. Demand and demonstrate safe firearms handling at all times.
Do not use the magazine tube for storage of additional ammunition.
Place one launcher load into the chamber. Close the action by moving the
forearm completely forward. The launcher load will cause the shaft and the
projectile to move upwards a short distance.
The shaft base must be in direct contact with the launcher load inside the
barrel. Ensure the projectile has not moved forward inside the barrel beyond
the depth warning indicator. Any gap between the shaft and the launcher load,
if fired, could cause serious injury, damage to the firearm or other personal
property, or death.
Firing the Line Launcher will produce substantial recoil. Fire from the standing
position, with the stock firmly against the shoulder, do not brace against a
permanent object for support. Lean forward with feet firmly planted. Leaning
forward allows the body’s natural motion to absorb the additional recoil. Do not
creep forward on the stock, and do not allow your thumb to recoil into your nose.
