Knex KForce 2016 Rotoshot Review

Last week, the people at Knex were kind enough to send me samples of their current blaster line for review, while we wait on the new models shown at Toy Fair to become available. My sincerest thanks to them! I’ll cover the Flash Fire in another post, since it’s a different animal.

The second generation of KForce blasters included motorized and multishot blasters. Two models of the Rotoshot (with a five dart revolving chamber) can be found for $40, each including over 200 pieces in addition to the main blaster unit. Do they perform, and are they worth it? Quite simply, it depends on your enthusiasm for building.

The Blaster Unit

The part of the blaster you don’t make yourself is very well built. The spring within is comparable to a Maverick in terms of power – short but stiff. The revolver turns on the prime, with the rotation mech resetting about 3/4 of the way into the priming motion. The entire unit, revolver included, unscrews, and the air restriction valves can be dropped out if you so desire. However, unless you’re adding barrel length, there’s no real benefit there.

An o-ring seals against the dart chamber, and does so very well. The unit is triggered by the orange piece in the rear, which lifts the sear when it moves. This orange piece is what has to be pressed by the trigger when you’ve made the blaster body.

All said and done, this unit easily fires darts 75′ using angled ranges, with my chronograph reading 71 fps with the included darts. So far, so good!

Building the Beast

Surprisingly, the box volume is FAR bigger than necessary for the parts included. This is probably more a reflection of the size of the end product. Big box is supposed to make you think bigger blaster and all that. Nevertheless, Knex gets a Black Hole award for taking up so much space.

Each kit comes with instructions for building the base model. In addition, you can enter the product code at to get PDF files with instructions for alternate models. As someone with decades of building toy experience, the full model only took me fifteen minutes to assemble. Your mileage will vary.

After the fact, however, I just didn’t like the size of the blaster, considering it only had five shots. So I tore the whole thing apart, and then built an alternate model in five minutes. It just felt better having a smaller blaster. Either option felt sturdy, by the way, and they held up great at an indoor war with no durability problems making an appearance.

In addition, having smaller blasters simply means more pieces are available for building the targets, or whatever else I can imagine!

Knex “Manta Rays” should be a thing, right?


The blaster is sturdy and fires well; I wouldn’t be afraid to use this in a fast-paced war, or even at an HvZ game. Knex proved far more durable than I ever expected for blaster applications. The only issue is the price. $40 for a five shot revolver is steep for someone only interested in blasters. If you’re willing to treat it as a two-part gift ($20 building set and $20 blaster), then by all means grab one.

    This is kind of cool. I am incredibly surprised to hear it’s not flimsy.

      Also, I think that the idea of building it on the fly and being able to customize is cool. What I like far better is that the semiauto blaster seems to have its flywheels/barrel/mag assembly as a standalone piece, which makes me really want to buy one and then retrofit it into an el cheapo airsoft playform. In other words, take the shell of some real-looking toy gun and cram the “nerf” guts into it.
