The Ark @fosscad.io DB Alloy test fires wont fully cycle the 2nd round.. help?
Originally posted by u/Bscott05 at 2025-06-25T16:54:39Z
as the title says.. I took out my first db alloy build yesterday to the range to test fire. I racked it and it shot the first round fine, but wouldnt reset the trigger, nor fully seat the next round into the chamber.. if i then manually reracked, it would eject the live round and reset the trigger and would then load properly so i could shoot.. but then the cycle repeated.. failed to load next round or reset trigger successfully. Could this be related to the mag? Not sure if the mag is the issue, this is my first print using printed mags vs oem.. using the normal sten mag file with a glock 33rnd spring. could the mag spring have too much tension on the stack that slows the bolt cycle? Anything else that would be causing this? I appreciate the help..
for reference, here is my build so far: [https://www.r

The Ark @fosscad.io G19 build - Sike Arms

Ok. While building this I came across an interesting issue.
I’m pretty much certain it’s my fault, but I need to understand what I’m doing wrong so I can fix my dumbassery.
After installing the internals into my Sike Arms frame I’ve found two problems:
- The G19 slide lock spring is stupidly loose. I’ve had to bend the spring out a bit, but I’m still not confident it’ll last. I’m going to order another.
- After putting everything inside the frame, the trigger won’t reset forward. It’s jammed against the back wall of the frame. I can physically tug it forward, but that’s by millimeters and it pops right back.
As I said before, I’m pretty damned sure this is caused by my own lack of experience. But I’ll never learn without making mistakes.
What am I doing wrong?

The Ark @fosscad.io Leber trigger reset/hammer follow issue
Originally posted by u/EdgeofthePage at 2025-06-25T12:07:08Z
Hey all, I have a printed leber lower for my mp5. It hand cycles snap caps fine. Resets fine.
I take it to the range and it fires, ejects the spent casing, feeds the next round, but I am getting hammer follow.
Any ideas? Common things that cause this?
Has a ptr modified ejector, standard fcg, extra power hammer spring...
Thanks in advance!
The Ark @fosscad.io How close are we?

This thing is basically my grail gun, how close to printing one are we? The Urutau is giving me "perfect is the enemy of fun to shoot" vibes right now, but ultimately my home defense gun of choice is probably gonna settle on something like this in a caliper ending in the name "blackout", and starting with either .300 or 8.6. Short barrel, stubby can, so a Blackout round makes much more sense than .223 family cartridges, until you start thinking about logistics, and the potential to get a .22 trainer bolt and mag kit.

From Atlantic, super cheap G3 kits perfect for Amigo Grande builds. Original barrels too if you prefer those.
The Ark @fosscad.io Could you 3d print a short barrel for a mossberg 500.

Like if I put a steel tube/barrel liner inside a printed barrel.

Finally completed the Apache chassis for my savage mk 2. So happy with how it turned out and saved my buying a chassis that’s more expensive than the gun.
