Not without more information
The best place to get information on the Remington 870 tactical rifle is on the Remington website. Another place to check is firearm forum where any questions or information can be shared through peers.
You will need a good gunsmith. The information you seek is not readily available in published material.
None that I am aware of.
Yes, The receiver pins are the same as the Remington 870, so any stock that will fit the 870 will fit the 7400
The 870 is unquestionably the best (stock production) pump action shotgun ever made and continues to be unsurpassed in design and function.
the rumor is any serial number on an 870 express ending with an M means its a magnum. I have one I bought in about 1987 and have shot thousands of three inch shells through it.
it could be any shotgun but my choice is my Remington 870, 20 gauge.
1600.00 I know that's on the 870 and what else i don't know but it's unlikely any Remington shotgun will bring that amount
Never heard of a serial that high, maybe that 7 is a 2?In any case you can tell the date of Model 12 with a serial this high because it will be date code stamped on the barrel. Please see related links for information on the Remington Society of America.
Compare letters in front of receiver below and behind choke to these on this page. http://www.remingtonsociety.com/questions/BLACKPOWDERX.htm
Could be several, need more information, patent dates or any other info?
You can call Remington at 1-800-243-9700 and go thru the menu selection. One of the menu options is to request information on your Remington based off the serial number. You read off your serial number and the guy looks up in the database the year the gun was made and what the original barrel was for that gun (if gun had barrel options like shotguns do).
