Sturmgewehr 556(S)
about
The Sturmgewehr 556(S) is a printable STG44 inspired rifle that is almost externally 1:1 with the real STG44, but can be made with commonly available AR15 parts.
It takes a design that is originally intended to be made using low grade sheet metal, and utilized modern materials with reinforcements as needed.
I had originally designed this to be made out of metal with my own tooling design, but when PSA shelved their STG project, several people immediately approached me and I modified the design to be printable.
The STG556(S) is configurable for many calibers and can feed from a variety of standard AR15 pattern magazines, and it can be upgraded with many modern AR15 parts and accessories.
Future planned DLC for the STG556(S) include:
-A pistol verison
-A 22lr version
-MKb42(H) inspired version
-Vampir night vision optics
