Colorado State Compliance.
We are not attorneys. We do have a legal analysis below from Attorney Janes T. Cook. Please refer to it for more detailed information, but this is gererally how we see it.
On April 10, 2025 governor Jared Polis signed SB-25-0003 into law in Colorado. This new law requies new gun buyers of certian specified rifles to complete an "extended firearms safety course" or a hunters safety course and a "basic firearms training course" every 5 years. These courses can be expensive, long, and require fingerprinting which can be used in a database of gun owners.
In the bill, specified semiautomatic rifles are: "A semi-automatic rifle or shotgun with a detachable magazine". This is pretty much every rifle out there except for bolt actions and pump shotguns.
We believe that using a permanetly mounted CompMag, would take many rifles out of the "specified" category because they would not have a detachable magazine.
In the bill it states "A firearm that has a permanently fixed magazine that cannot accept more than 15 rounds of amminition, including a semi-automatic firearm that has been converted to have a permanetly fixed magazine that cannot accept more than fifteen rounds of ammunition" is not included in the specified semiautomatic category.
The CompMag must be permanetly attached with epoxy: on the AR models, by epoxing the release hhole cover on, and on the AK model, by filling the hex hole and the srcew holding the mag into the receiver.
