The third box has 2 numbers and 2 letters in it. The top 2 boxes are clearly marked with "Serial Number" and "Order Number". At the right end of the label are 3 boxes. If you cannot read the letter on the barrel and you still have the box, you can get the information off the label. If you read the letter for each month in order from January to December, it reads BLACKPOWDERX. This means this rifle was manufactured in January of 2015 and Remington confirmed this too. This means this rifle was manufactured in February of 2017 and Remington confirms this. The month letters are as follows B = Jan, L = Feb, A = Mar, C = Apr, K = May, P = Jun, O = Jul, W = Aug, D = Sep, E = Oct, R = Nov, X = Dec See the month and year letter list below. Of these 2 letters you see on the left side of the barrel, the first letter tells you the month and the second letter tells you the year of manufacturing starting with the letter E = the year 2010. If the letter looks like an "I" then it is an “I”, not a lower case L. These letters are much smaller and may be a very light stamping so you may need a magnifying glass to read them. (See photo below.) This is same place you would look to see if the rifle were a JM Marlin. Now if the serial number starts with MR, we have to look at the left side of the barrel where it screws into the receiver. If the serial number starts with MR then it is a Remington made Marlin. The only thing the serial number tells Remlin owners is if the gun was made by "Marlin" or "Remington Marlin". The new Remington Marlin serial number is computer generated. I own 3 Marlin 1894 rifles, but only 2 are Remlins and this decoding works perfectly to get the correct manufacturing date according to Remington. I am copying his post here along with other photos to help you can understand when your new Remlin was made. at the following link,, is 100% correct. Here is the low down directly from Remington that I got from an original Marlin employee. I include his post below (I deleted photo attachments since they required login to forum to display): I found this information from a Marlin forum from a poster's response to finding Marlin production dates for those made by Remington. Hence, as far as I know, the rifle's production date was May 2018. The code on the left hand side of barrel near the receiver is KM.
