#### Description
|
||
|
|
|
||
|
|
These files contain the design for a 3D printed .22 LR Semiautomatic firearm, meant to be used as a handgun. This design uses a modified 10/22
|
||
|
|
magazine, HOWEVER, it must be printed and the resulting magazine will NOT work in a 10/22 rifle.
|
||
|
|
|
||
|
|
#### Features
|
||
|
|
* Rifled Barrel for ATF compliance
|
||
|
|
* Metal insert for case extraction
|
||
|
|
* Easy to use magazine release/catch
|
||
|
|
* Sectioned receiver, can be printed on printers with 6x6x6" total build area
|
||
|
|
* Can accept either a 10 or 30 round magazine
|
||
|
|
* Almost entirely polymer, lightweight
|
||
|
|
|
||
|
|
#### Instructions:
|
||
|
|
Print out all parts included except the firing pin and AR-15 FCG simulations. The receiver must be in a material that can be
|
||
|
|
fused, preferably using MEK. MEK works well on ABS plastic so this is reccomended. Do not use PLA for anything, unless you are an
|
||
|
|
Australian police force.
|
||
|
|
|
||
|
|
Obtain the following metal parts:
|
||
|
|
* AR-15 FCG (These may be possible to print in the future)
|
||
|
|
* 1x8mm Metal insert (This is the same as the insert used in the Reprringer v2.0 pistol and is use for extraction)
|
||
|
|
* Ruger 10/22 Magazine spring
|
||
|
|
* AR-15 Buffer Spring
|
||
|
|
* AR-15 Firing Pin
|
||
|
|
* 8 245gr .44 bullets (These are used to bring the bolt weight up to the required 0.4 lbs)
|
||
|
|
|
||
|
|
Other than the FCG, all of these MUST be metal for a semiautomatic design to function. The FCG is currently not suited for printing.
|
||
|
|
|
||
|
|
Assemble as shown in the assembly. If you had to print the receiver in parts, use MEK to combine them. The buffer spring must be glued to
|
||
|
|
the receiver and bolt. The .44 bullets need to be secured using something such as epoxy.
|
||
|
|
|
||
|
|
You will also want to either print or purchase an AR-15 pistol grip.
|
||

#### Safety/Disclaimer
|
||
|
|
The creator of this weapon is not responsible for any injuries or legal problems that arise from creating and firing this design.
|
||
|
|
You, the manufacturer, take responsibility for any issues that may come. Take precautions when firing (Fire with a string for first
|
||
|
|
shots) and be sure to follow all local firearms laws.
|
||
|
|
|
||
|
|
#### Legality
|
||
|
|
This weapon is NOT legal to print in California, unless you are an FFL or an FFL modifies this design (Zip Gun Law). The 30 round magazine
|
||
|
|
may not be legal in your area. This weapon is NOT legal to print in NYC, as weapons made on 3D printers are prohibited. If you
|
||
|
|
are in the U.S., the Undetectable Firearms Act may apply, in which case you will need to epoxy 3.7 oz of steel into the receiver.
|
||
|
|
Even if your area is not listed here, be aware of your local laws.
