Note there are 12 letters, one for each month. The first letter indicates the month of production by its position in the word BLACKPOWDERX. Year of production is indicated by two or three letters stamped on the (usually the left) side of the barrel near the chamber. Their serial numbers do run consecutively. Remington uses a completely different system. I think they are not, at least not from year to year. I do not know if the rest of the following serial numbers from Marlin (after the first two) are consecutive. This is not so difficult, since the really old ones have different model numbers, calibers, stock styles, and imprinting text fonts. This assumes that you can tell the difference between a 46 year old rifle and one that is over 100 years old. If the first two numbers are 96, subtracting from 2100 give a production date of 2004. If your first two numbers are "26" the subtracting from 2000 gives a 1974 date of production. Further back Marlin used letters for the year of production, and farther back still, the serials were all consecutive. After the year 2000, those first two numbers are subtracted from 2100. Before the year 2000, subtracting the first two numbers from 2000 will give the year of manufacture. Marlin changed the first two numbers of their serial numbers each year. Marlin and Remington use(d) different serial numbering systems and different algorithms for imprinting fire arm manufacturing dates. To be clear and to address the original question.

It gets assembled, boxed up, and sent out the door. When you get into lower end stuff - especially rimfire - a lot of companies don't even test fire. If all goes well with that function test, it is sprayed clean, allowed to dry, coated with a preservative, and boxed up. If it looks good, it is then fed two to three magazines (15 rounds each) of standard US manufactured 9mm ammunition. The Maxim 9, for example, gets a proof load and then an inspection. SilencerCo proof tests all of their non-suppressor firearm products. I've never gotten an explanation from them, but Ruger doesn't use Federal ammunition for test firing, unless it's the only reasonable choice on the market - due to niche cartridge, other brands only make +P, etc.) Hornady makes most of the proof loads, as well. (Which varies, but is typically Remington UMC, Hornady, or Winchester. The rest are only test fired with standard ammunition.

Ruger, for example, only proof tests about half of their products.

Some companies are even split with their own products. There is a big difference between proof testing with industry standard over-pressure loads, and test firing with standard ammunition. A few gun manufacturers proof test their firearms, but most do not.Ī much higher number, but still short of the whole industry, test fires their firearms. Click to expand.No, the majority of US gun manufacturers do not proof test.
