I chose the K26 option with a 18 inch barrel. It has worked perfectly, although there is one problem. The gun is literally so powerful that if you shoot a surface that is too hard, the tip of the nerf dart will completely shatter. sheesh.... i'm nervous about shooting anything with it. Great kit, everything came in perfect condition and fit well.


Everything is great. The only suggestion I have is they could use a tap and drill bits for the holes on the aluminum bars in the kit. I think my 11 year old son stripped the holes out when trying to **** a couple in. There are two screws on top of the Caliburn that holds the two bars to the part falls out. Or, suggest tapping it in the instructions. I didn’t help him build it since it was own project over spring break to print and build on his own. I emailed CS to see if I can order replacement bars over the weekend.

My son loves it. Thank you Out of Darts and Captain Slug for this kit.

Pretty Good

The hardware kit was complete and with generous spares of easily lost items. Fabrication on the aluminum rods was a bit rough around the edges though. Well, not literally, there weren't any sharp burrs, but the threaded holes were a bit rough and chewed up. Looks like a lack of lubrication or chip clearing, or just a dull tap. Everything went together fine though, and the blaster works perfectly! Would buy again.
