about 20-30 feet
Nerf Alph trooper is by far better
The Alpha Trooper far outperforms the deploy. Deploy comes with six-round clip. Alpha Trooper comes with 18-round drum. Deploy gets 27 ft. ranges out of the box. Alpha Trooper gets 33 ft. ranges out of the box. However, Alpha Trooper is only at target. Deploy is everywhere. Hope this makes the answer clearer.
most likely the alpha trooper, its affordable, shoots far, has good capacity, and it has great rate of fire.
35 feet
The Nerf nitefinder can shoot up to 36ft (10.80m) without modifications. Trust me, I have done it before.
It can shoot 30 or 35 feet normally.
The Deploy can shoot up to 40 feet if you are lucky.
about 30 inches
50 ft
About 15+ feet.
about 25-30 feet
1700cm, or 10.7m but you can mod it to shoot way further
