Updated DX-7 Rifle Receiver 3D Printed

Build process of the 3d printed DX-7 rifle, which utilizes a milled or 3D printed receiver to house primarily AKM components. The first 3D printed DX-7 had steel rails but they were only held in place with melted plastic studs. You can see me using side cutters in the video removing them to drill holes for pop-rivets. These plastic studs failed to hold the rail in place and eventually caused the gun to jam on the 397th round. I also use threaded brass inserts to keep the holes from stripping out of the plastic, which was also an issue on the initial build. These two upgrades should greatly increase the reliability and serviceability of this gun. After I finished filming I DROPPED the upper receiver and barrel assembly on my garage floor. The assembly landed on the rear of the upper, the two tails where the take-down pin goes through. I couldn't believe it! So in order to fix it I grabbed some super glue and prayed it would hold and.....it seems like its going to work! It feels very strong and I haven't been too gentle with it either. I will have and extra receiver with me when I go to test just in case that's where it fails. I will show the repaired tail when I go to shoot it just so its clear that the receiver is the same one for the entire test. Thank you for watching and stay tuned for more updates. I have been working on a deal to get the DX-7 into production and it is going very well. I should have more news on that soon and I would like to document some of the machining process if anyone is interested.Show more
