Hey,
i’m not able to get AR lower parts and springs… Which springs should i use to substitute the AR springs? As far as i understood 4mm rods can be used as pins, but the springs are still an issue…
Greetings
I’ll post this here so everyone can see instead of the chat.
There’s ar spring jigs to make you own springs or the cm-1 fcg.
i think its more about the small compression springs, if somebody does not want to use the cm-1. trigger and hammer springs are known to be possible to be homemade.

In the guide BOM you mention a “6mm x 200 rod recoil spring guide” but nothing on a recoil spring. Am I missing something? And thank you for your work!
The 11" spring. The latest 1.2 guide was updated. All my designs use the same materials wherever possible. It helps to keep cost down and simplify design by re-use.
could you please mention the specs of the fcg springs vitehe circled in the picture?
Hey dude, I made a BOM for the ar FCG for people looking for the diy alternative. Tis on the sea :)
