Modifying Magazines to Limit Capacity

[def90]

The law only states that you may not buy or assemble a magazine over 15 rounds so yes it is legal for an individual to assemble a 15 round or less magazine.

Though I haven't quoted the specific verbage if you read it it is pretty clear, I don't see where there is any ambiguity.

As for "permanent" modification vs non the term in general for most firearms related things has meant that the item in question cannot be reverted back without using tools. A loose block in a magazine could be considered easily convertible as all you would do is remove a base plate without any tools and pull the block out, a rivet would likely be considered a permanent fix as it could only be defeated via using tools such as a drill which would then be interpreted as you physically modifying an existing product.

The law says “designed to be readily converted”, the mag block is not designed to be readily converted and companies like Charlie Coopers based in CO will ship the 30s with just the mag block right to you. (I don’t get anything from them, I’ve just had a good experience with their mags and service)

I like your definition of "without tools"

With tools, nothing is permanent.

The ambiguity to me is "are the components legal to buy if not assembled"?

Maybe I read too much into it. I think it is sorta like an NFA type thing where someone says it is constructive intent.

An FFL?

No, you simply state you are a magazine manufacturer, which is exempted from the mag ban. You can do business as your legal name without a license. You do not have to file taxes on any business you do not make more than $400 in a year on, including a DBA your name.

Therefore you're exempt from the mag law and taxes on that business or even having to file.

As far as the OP’s concern of running into overzealous LEOs while in possession of +15 round magazines, didn’t we have a thread a few years ago from a member here that had a Denver PD officer try to confiscate some +15 round magazines while the member was using the range at Cherry Creek ?

While I don't remember this particular incident, a member of the DPD would have no authority at Cherry Creek as it isn't within the Denver city limits/their jurisdiction. It resides in Arapahoe County.

Very interesting.

They just have to have a date code stamped on them, correct?

I may have misquoted the LE agency. But for some reason I think this was the whole point of the thread, DPD trying to confiscate magazines at Cherry Creek State Park.

The AG back in 2013 stated that a magazine is legal if it requires others items (buying a different follower or floor plate for example) OR permanently alter them (drilling out a rivet for example) to increase capacity. Link below for the actual document from the AG office.

Since a mag blocked magazine requires you purchase "additional equipment", which is a different follower to increase its capacity, it would be legal according to the AG without the need to glue the floorplate IMO. If you're like me and shoot in the rain, snow, and dust, being able to clean your magazines is a must.

I believe the whole "designed to be readily converted" part of the law was to ensure removable base plates wouldn't effectively be banned.

Hopefully this helps.
