Description shotguns Remington 11-87 Sportsman
Semi-automatic smoothbore shotgun with a tubular underbarrel store. Recharge is carried out through selection of the portion of the propellant gases from the barrel. The piston and return mechanism located on the exterior of the shop and closed fore-grip.
The design of the gun was very similar to the device, for example, Mossbreg 930, which almost without changes is taken the shutter, and “Snipe-Car”, with a very similar design of a gas engine.
Advantages and disadvantages
Traditional Remington optimal ratio of price to quality. That is, this gun is average in everything it does have something to complain about, and admire.
- The gun comes in two calibers – 12-m and 20-m with 76 mm chamber Is better than the sentence “Snipe-Auto” and Mossberg 930, which run in the twelfth. However, it is strange that omitted a popular 16th, which is the optimal diameter of the shot scree for most types of hunting. Semiautomatic 20-gauge is a very controversial decision, because usually with the same diameter of the barrel hunting for upland and wetland game that rarely gather in flocks and the entire process is very fast. So much so that even twin shot is a rarity. And the third cartridge to shoot is not for someone.
- The shutter free, he almost without modification is borrowed from a Mossberg 930. Due to this recoil even when firing the heavy duty rounds of 12-gauge remains quite moderate, it is much less than the “Snipe-Car”, the larva of the shutter which engages a tooth over the shank of the breech. However, the sharpness and accuracy of the battle at the weapon with this type of locking of the barrel is always a little worse.
- The handle of the bolt is small, to pull her hands in the gloves can be awkward.
- Nice gun digests all kinds of ammo, including with reusable brass cartridges. But prefer standard or enhanced linkage of gunpowder.
- The functionality of the Remington 11-87 Sportsman is slightly inferior to “Bekas-Auto”, which has a trap of cartridges, which allows you to quickly change the type of the equipment used cartridge or not to empty the store of weapons transport – when the monitoring officials of the Ministry of interior to open the shutter and do not apply cartridge to the line of loading.
- The fuse box is located otherwise than the Mossberg 930 – branch on the rear of the trigger guard, not on the back plate of the receiver. This design is usually for Remington, but cannot say for certain that it is the other hunters there.
- The design of the gas engine does not allow to increase the capacity of the store. However, it is made of stainless steel, so care for guns much easier.
- The ergonomics of the box is not satisfactory. This is exactly what Remington 11-87 should be commended.
- Shotgun 12 cm long “Bekas-Auto”, and 150 grams heavier than him, but overall dimensions and weight are in the normal range for this type of weapon.

The cartridges fit into the hopper sequentially muzzle of a cartridge case forward. To feed the first cartridge into the chamber distort the bolt. Then the store can put another weapon.
When moving the bolt back manually by a handle or by pressure of gases on the piston – removed and ejected the used cartridge case, the percussion mechanism is cocked, is fed into the bunker cartridge. During her return, the Elevator delivers the cartridge to the line loading, where it is picked up by the larva and is fed into the chamber.
After shooting the last cartridge slide is to delay. It can be removed by pressing the lever located in front of the trigger guard.
The weapon has no perehvatyvaet ammo, so charge one cartridge with other equipment is possible only with an empty store. To do this, pull the bolt back, put the ammunition on the Elevator through the window of the receiver and press the lever removing it from the receiver delay.
