Question Why are mags date stamped?

Sorry if the answer to this has been addressed here, but I did search before posting.

During the period in which the 1994 Crime Bill was in effect, it was illegal to manufacture a "large capacity ammunition feeding device", except for export or for sale to a government or law enforcement agency. And this apparently provided the reason for magazine manufacturers to stamp high capacity magazines with "RESTRICTED LAW ENFORCEMENT/GOVERNMENT USE ONLY" or something similar.

It is not clear to me why magazine manufacturers ever date stamped their high capacity magazines, but since the 1994 Crime Bill expired in 2004, why does this practice continue?

TIA

Who's date stamping?

Even if they are date stamping, what does it matter except to identify which lot that particular magazine came from.

Date stamps tell the age of a product and sometimes additional info about that particular magazine.

Magpul date stamps all of their mags so you know the vintage of a mag.

08/2009 for example

They are doing it for the express purpose of denying Californians the ability to acquire USGI mags and then claim they were possessed in the state prior to the Jan 1, 2000 ban date. It is a conspiracy.

Who's stamping? Government contractors such as Center and Okay, and apparently Magpul.

Quality control as a reason makes sense, but I wonder about the coincidence with the Crime Bill. Maybe it's just a coincidence.

Thanks for the thoughts.

Take a chill pill, homie. It's called a joke, and you failed the humor test. Try again next time.

Default How could a high capacity magazine with a 2010 date be legal?

I understand how an old high capacity magazine could be illegal to the present owner, although I do not know how the legality or illegality could be conclusively determined, but I do not see how a 10/12/2010 magazine could be legal. Of course if you have repaired an old magazine with new parts that have a recent date stamp on them it could still be legal, but if the magazine itself is new I can not see how it could be legal (without some special permit or some such).

Everyone is in fact referring to the fact that the newly stamped magazines are rebuilt from previously owned, pre-ban magazines. The burden of proof lies with the prosecuters and date stamps are not conclusive, so really there is no way they can tell whether the mag was rebuilt or not. Possession of hicaps is not illegal, but once they are inserted into a firearm that has evil features, mag lock or not, it becomes illegal.

Other states(like New York I think) can buy high caps as long as they were produced before a certain date.

The main reason why manufacturers still date stamp is because unlike California, which banned acquiring them all together, there are some states, such as New York, that still allow you to purchase and use pre-ban firearms and magazines. The date itself means NOTHING in California, but to places like New York it can be the difference between legal and illegal. Military contracts will frequently date code their products, both for quality control and contract run quotas but it's not required. For companies like Triple K or ProMag or some of the other companies that may do it just to do it, it's strictly for Pre-ban/Post-ban states.... which again, we are not.

Wrong. Features has nothing to do with high cap magazine useage. That is left over thought patterns from the federal AWB which prohibited magazine capacity size on post-ban rifles. Configuration is the rule of the land, and with fixed magazine rifles, 11 or more rounds is a feature of the gun, not the magazine itself (as per the law, the magazine is part of the gun itself by definition which is why options like the bullet button can exist in the first place).

In California a RAW can use ANY magazine it wants and a legally owned magazine can be TEMPORARILY altered to only hold 10 or less rounds and used in a fixed build magazine. The reason for the pertinance behind permanently modified magazines is so it can not be construed that a seller was importing and/or selling high cap magazines in low cap disguise.

Dude, that's what I said. A fixed magazine over 10 rounds makes it illegal as opposed to a featureless rifle using hicaps. And I am aware that a RAW can use whatever size magazine.

I'm really not trying to pick on you so please don't take it that way. I'm just trying to correct the details because there are so many people who have no idea in regards to our laws and I don't want them confused, doing something they shouldn't, or just spreading general FUD.

The first 6 words are correct, and the rest is not. RAWs aside, a magazine limiting block can be non-permanently used in a legally owned high cap and used in a fixed magazine gun. Also, it should be pointed out, that a featureless rifle with an 11 or more round magazine with normal AR magazine button release is legal, but with a fixed magazine, even when featureless, it is now an assault weapon (the fixed magazine becoming a feature and no longer an ammunition feeding device). On a fixed magazine gun, the magazine is not an auxilary device but is part of the gun itself as seen with the DOJ's addressing of M1 Garand enblocs being "removable". Once in a fixed magazine gun, the magazine's configuration is a characteristic of the rifle and not an accessory.

It's subtle differences, and it IS confusing as hell, but it needs to be addressed for people that might try to logically assume outcomes with illogical firearm control laws.

I don't think you understand the California "Large Capacity" magazine ban.

Continued Possession and Use of Large Capacity magazines is LEGAL.

If you posses a Large Capacity mag, you can repair or replace EVERY part of it.

You are NOT required to only use "Preban" parts (so date stamps mean nothing). Nor do you have to use parts from the same manufacturer.

Since you can LEGALLY replace Every Single Part of an existing Large Capacity mag, you can rebuild an old 20 or 30 round USGI metal mag with all Magpul Pmag parts and in effect have a Magpul Pmag that is TOTALLY LEGAL to own and use.

Everything is aimed towards CA! Companies are date stamping so it'll be illegal to posses if we had it after 2000!

Has anyone ever been arrested over it yet? I know hassle yes, from uninformed LEO, but has it gone so far as to be arrested over a rebuilt mag where the police think it's simply illegal to posses a high/normal cap magpul mag?
