The serial number is MR505XXB
Can anyone out there help me with a manufacturing date/location?
I just picked it up in a trade with no box.
Hey Rolan. Can be tough to ID DOB on some of the newer MR's. See attached PDF of Remington's Date Codes cryptography. Good until 2012. Yours could be newer. On the left side of your barrel, near the receiver, you should find two letters. Use the attached PDF to figure it out. First letter is the month & 2nd the year. I have many JM (North Haven, CT) 1894C Marlin's but also one perfect fit/finish/function MR (Ilion, NY) 1894C. For instance it's barrel is marked RF which would translate to R=Nov & F=2011.
Lemmeknow what you find. By the way. For the time being, partially ignore all the comments here about the horrible nature of ALL MR Marlin's (Remington made). Many MOF members have perfectly functioning Remington made Marlin's, myself included. Many others have not been as fortunate. In fact some have had seriously flawed MR's. Hopefully you have a good one. Get some dummy rounds, or go to the range with live rounds and she how she feeds. Be wary of those cheap aluminum Zoom snap caps. I have a JM 1894C which feeds live rounds just fine, but chokes a little on those Zoom's. If its pretty new, and not broken in you may need to operate the lever with authority, but don't force it too much. If you get a jam or two, try to see how/where its jamming. Try plain old ammo, with as flat a nose as possible. NO POINTY STUFF and steer clear of semi wadcutters as some 1894C's don't like 'em. I have both. If all you can find is 357 round nose, thats OK. Your just checking function. Don't worry about a few hiccups.
If it feeds OK, it will lead on to several other checks. We'll cross that bridge later. I'm no expert, but have been around a LOT of 1894C's, stripped them down to every nut, bolt & spring & have learned a LOT. Mostly from the true experts here on MOF. Some may not respond or respond with something snotty about crappy MR's. That's the part you need to ignore . . . for now. If everything else is OK, a slight feeding problem can be fixed if your handy & know your way around firearms. I'm hoping you have yourself a good one & looking forward to your response.
