SKS blowback kit（only upgrade kit）

https://www.youtube.com/watch?v=CYLB0rHkLiw blowback kit only. All parts of sks are not included. I made my model based on the following mold. Some models are newly created, while others are modified to include structures that are not suitable for printing in the free model (as the free model is a completely real gun design that is too small or thin for printing). The dimensions of all parts of my model are different from those of the free model (because 3D printing requires some space to make up for printing tolerances). If you think my job is not worth your money. Then you can download the free model for printing and testing first. (Friendly reminder: Free models cannot be assembled after printing.) Finally, thank you very much to the designers of these original models. I hope everyone can get their favorite models. Final statement: I provide technical support for purchasing my model. If you encounter any problems during the printing process, you can send me an email and I can help you solve them. (Email content: 1. Screenshot of the purchase model record 2. Screenshot or short video of the problem you encountered 3. Text explanation of the problem you encountered. Generally, I will reply within 24 hours. The maximum time is not more than 48 hours. If I haven't replied within 48 hours, there may be too many emails that I haven't seen. You can send them multiple times or leave me a message on YouTube.)
