***UPDATE: Files available on Defcad.com and Fosscad Twitter!***
I have designed a .22 LR Semiautomatic firearm. Unlike former designs such as the Shuty, this design uses almost all plastic parts (All non-plastic parts currently except the FCG cannot physically be plastic or a semiautomatic will not function) and uses weights to bring the bolt to a correct weight. You will need the following parts:
*3D Printer with ABS capability
*AR-15 Buffer Spring
*Ruger 10/22 Mag Spring
*AR-15 Firing Pin
*1x8mm metal insert (Case extraction)
*.44 bullets to weigh down bolt (More info in the .readme)
The barrel uses an insert around the case, but then the rest of it has a plastic bore, which means it is pre-rifled and therefore complies with the ATF.
Magazines available in 10 and 30 round versions. NOTE, although they are based off of 10/22 magazines, they MUST be printed as they contain a built in mag-catch and will NOT work in a 10/22 rifle.
Credit to nilsson for original 10/22 magazine design and Shanrilivan for the part of the frame that holds the FCG, which was derived from the Charon v3.0.
Suggestions are welcome, testers even more so.
EDIT: Just to confirm, these plans are from the group Fosscad. Also, it appears the name Brick has stuck and there is nothing I can do about it, lol.
