Description
Kaewon’s Wisp is one of the first fully printable bolt action rifles to be released to the public.
This hardware kit is aligned to V1 of the files. This means the kit will ship with bolt and breach face that BOLT on to the bolt, rather than attach via JB Weld.
BYOB will be the most common option for this kit, leaving you the option to source an RS22/Mossberg 702/10-22 barrel, or to use a liner. The files in this build are set that you can use whatever length liner you’d like, you just need to print the barrel to match. The recommended way to build this is to use the BYOB kit, and order whichever length barrel liner you’d like to build it with separately. I’ve added some common lengths as options.
The Magazine spring ships as a 300mm Spring. This is long enough to make the biggest magazine included with the Wisp files, or 2 of the smaller magazines.
