Blaster is compatible with FULL-LENGTH and Half-length dart magazines. It is also capable of loading 1 to 4 darts at a time by simply cycling the breech more than once per priming stroke.

The Caliburn is a Mag-Fed Pump-Action Homemade Nerf Blaster design released as a PUBLIC DOMAIN file set by Captain Slug (http://www.captainslug.com).

WARNING: This blaster MAY NOT BE SAFE FOR INDOOR PLAY. Even with the weaker spring, the o-ring removed, and firing full-length darts this blaster will easily shoot faster than 110+ fps. So keep this in mind as to where and when this blaster is used. It can and will produce welts at point-blank range.

You are welcome to and encouraged to modify the files in any way you want. The Majority of the parts can be printed with infill as low as 20% in PLA, but I would recommend printing in layers of 300 Micron or smaller.
