The Remington 11-87 is a semi-automatic shotgun manufactured by Remington Arms. It is based on the Remington 1100 and was first announced in 1987.
The 11-87 is a gas operated semi-automatic (autoloading) shotgun, meaning that some of the high pressure gases from the burning gun powder are diverted through two small holes in the under side of the barrel.[2] The gases force a piston (and the bolt) toward the rear of the shotgun, which in turn ejects the spent shell. A spring then forces the bolt forward, sending a fresh shell into the chamber. This gas operation has the effect of reducing the recoil felt by the shooter, since the total recoil energy is spread out over a longer period of time than would be the case with fixed breech shotguns.[2]
The 11-87 incorporates a self compensating gas system design, which allows the gun to operate with every type of load from light 2-3/4" loads up to 3" Magnum loads without any shooter adjustments. It is manufactured in two different gauges, 20 and 12, and both will handle 2-3/4" and 3" shells. Recently a Super Magnum version has been introduced to operate with the newer 3-1/2" 12 gauge shells.[3] Some 11-87s have interchangeable screw-in chokes, although barrels are available with fixed chokes. Most barrels are not interchangeable between 1100 and 11-87 models. Barrel length are from the police 14 in (360 mm) up to 30 in (760 mm).[4]
