Colorado form 1 & 4 transfer data / wait times

[electronman1729]

Does the 3 day bullshit apply to gun mufflers? And do you have to wait 3 days to assemble you'd shorty after stamp issuance?

Depends

By the time you certify to approval is minimum 3-days. (Assuming for a trust)

When individual approvals were taking less than 24 hours, some shops still might say silencers are not firearm's.
