| The Remington Model 870 side-ejection slide-action shotgun was introduced to the public early in 1950 by Remington Arms Company and were originally offered with fixed choke barrels. The model 870 was made available in 20 gauge, 16 gauge and 12 gauge with 2 3/4 inch chambers and 3 inch magnum chambers. Magnums offered a three shotshell magazine tube capacity and the 2 3/4 inch magazines would allow a four shotshell capacity.|
The chamber is the opening at the rear of the barrel where the shell is placed for firing. A standard length chamber is for 2 3/4" shells. A magnum length chamber is for 3" shells. In many cases, shotguns with 3" or 3 1/2" chambers also function with shorter shells like the "Remington Model 870ä Express Super Magnum". Shotguns with 2 3/4" chambers and barrels are designed for use with 2 3/4" shells only. Always match your shotgun shell with your barrel and receiver.
The 870 features a bottom-loading, all steel, side ejecting receiver, tubular magazine under the barrel, dual action bars, internal hammer, and a bolt which locks into an extension in the barrel and is very easy to disassemble for thorough cleaning after heavy range or field use.
Remington 870 Disassembly:
Disassembly of the Remington 870 is very simple and easy enough for most people to do without much instruction or extreme amounts of gunsmithing skills.
Trigger Assembly: To remove the trigger assembly, you first set the safety to the safe position, then on the side of the receiver there are two pins, using a drift, remove the front and rear drift pins, lift the rear of the trigger assembly and slowly pull to the rear of the shotgun or towards the rear stock, slightly turning it clockwise to clear action bar lock, complete removal.
Barrel: To remove the barrel make sure gun is cocked and safety on, then depress action lock and slide the fore-end halfway back to open the action, unscrew magazine cap nut at the end of the magazine tube and remove it, now remove the barrel.
Breech Bolt: Now that you have removed the trigger assembly and the barrel removing the breech bolt is accomplished by depressing the left side shell latch which is visible while looking through the bottom of the receiver, depress shell latch and and slide breech bolt and assembly forward toward the magazine tube.
Magazine Spring And Follower: To remove the magazine spring and follower care must be taken while performing this removal as the spring does have tension on it, use a flat blade screwdriver and insert it into the slit of the magazine spring retainer and slowly pry the retainer from the magazine tube keeping at least one hand over the magazine tube to keep the spring from launching itself from the magazine tube, remove the spring and follower. Reassemble in reverse order of disassembly.
Early production 870s had a design flaw whereby a user could fail to push a shell all the way into the magazine when loading. This would cause the gun's action to bind. This issue was resolved with the introduction of the "Flexi Tab" carrier.
Remington 870 Barrels:
Remington 870 shotgun users have many barrel configurations available to them from the Remington factory for their Remington 870 shotguns which is another reason for the large popularity of the Remington model 870 shotgun. Model 870 Barrels with 3" chambers will fit both magnum and 2-3/4" receivers and will handle both 2-3/4" and 3" shells with a magnum receiver. (An M at the end of the serial number = magnum receiver.) Use only 2-3/4" shells when barrels are used on 2-3/4" receivers. Remington 870 Special Field barrels and other model 870 barrels are not interchangeable.
Barrel length is really a matter of personal preference and often depends on terrain and the type of game you are hunting. Generally, longer barrels aid in pointing and are often preferred for pass shooting waterfowl and shooting targets such as skeet, trap and sporting clays. Shorter, more compact barrels can provide faster handling and are often chosen for hunting upland birds, turkeys, deer with slugs and buckshot. Common barrel lengths for the Remington 870 shotgun include 20", 21", 23", 26", 28" and 30".
The original Remington 870 barrels were offered with fixed chokes. In 1986 Remington introduced the new Remington "Rem Choke" system of screw-in chokes.
Remington 870 Rem Chokes:
Rem Chokes are a system of interchangeable choke tubes that allow you to quickly and easily change the choke of your Remington 870 shotgun to match specific hunting conditions. Rem Choke tubes are made from the highest grade of heat-treated, seamless stainless steel, giving them the strength to handle steel or lead shot without wear or loss of constriction.
Super-Full and Extra-Full Rem Chokes: Specialized chokes with extra-tight constrictions and the densest patterns, ideally suited for the head shots necessary in turkey hunting.
Turkey Super-Full Rem Choke: Constriction is reduced to .665"
and delivers 85%+ patterns at 40 yards when used with Premier® Magnum Turkey Loads. Front of tube is knurled for a good grip and easy removal, and extends out beyond end of barrel by approximately one inch. Not for use with steel shot.
Turkey Extra-Full Rem Choke: Offers extremely tight patterns and dense pellet concentrations at long range, .687" constriction will put 80% of pellets in 30" circle at 40 yards. Not for use with steel shot.
Full Rem Choke: Tight constriction for dense pattern will put approximately 70% of a shell's total pellets in a 30" circle at 40 yards. Best for trap shooting, pass shooting waterfowl, turkey hunting and shooting buckshot loads. Delivers tight, well-placed shot patterns when shooting between 45-55 yards. Ideal for ducks, geese and long-range pheasants.
Modified Rem Choke: Less constriction than full choke will put approximately 60% of a shell's total pellets in a 30" circle at 40 yards. Excellent for all-around hunting of waterfowl, long-range flushing upland birds such as late-season pheasant and sharptail grouse as well as other small game. Also used for trap shooting. Choke that delivers wider shot pattern for shooting at 25-45 yards. Great for squirrels, rabbits, pigeons, doves, partridge, grouse, pheasant or wild flushing quail at medium range. Also ideal for pass shooting ducks and geese with steel shot.
Improved Cylinder Rem Choke: Even less constriction than modified will put approximately 50% of a shell's total pellets in a 30" circle at 40 yards. Ideal for close-in small game shooting, upland bird hunting such as quail, grouse and pheasant as well as hunting waterfowl close over decoys. Rifled slugs also perform very well from this choke.
Cylinder Bore Rem Choke: No constriction will put approximately 40% of a shell's total pellets in a 30" circle at 40 yards. Most often used by law enforcement for service shotguns.
Skeet Rem Choke: a specialty choke will put approximately 60% of a shell's total pellets in a 30" circle at 25 yards designed to deliver optimum patterns for close-range skeet shooting. Also good for close-range upland birds.
Improved Skeet Rem Choke: Slightly tighter choke for skeet shooting will put 65% pattern in 30" circle at 25 yards. Great choice for doubles or windy conditions.
Rifled Rem Choke: Adds rifling to smooth bore barrels equipped for Rem Chokes. Adds rotational stability to Foster-type and sabot slugs as they exit the muzzle, improving accuracy and shot placement. Available in 12-gauge only.
