What it does

- Fits Russian, Chinese (Type 56 and variants) and Yugoslavian SKS receivers, and others with the same geometry
- Picatinny / 1913 buttstock interface, so you choose the stock
- Bayonet compatible; under 400 g printed in PA-CF
- Download includes all STL files and a README with print settings and assembly instructions
- Needs the XCR rifle modification, or it drops straight in if your rifle already runs a Hi-Cal-style adapter
