>>6667133Boomco ammo has the potential to shoot way further than Nerf due to its low weight. They're also very solidly-built. So look into which of them can be modified. The Boomco M6 pistol in particularly is extremely popular for this reason.
Rival shoots a lot further when stock than dart-firing blasters do when stock. Their intended age bracket is higher after all. The downside of Rival is that the ammo becomes useless at higher muzzle velocities. It's also much much more expensive to buy aftermarket Rival rounds than it is to buy aftermarket darts. You can get 1,000 aftermarket darts from several places for around $45 shipped.
