Design

Mr-27M consists of a receiver with a stock and barrel unit with the forearm.

  • Trunks joined in a vertical plane and connected breech coupling and milwalkie straps – two side and top. Top refers to the type of vented. Locked trunks due to shifting of the locking bar: it is inserted into the opening of the hook on the clutch. When you open the trunk bar and the release lever is held by the delay. When closing the gun delay automatically releases the bar.
  • In the receiver block with the drilling of the Lancaster connection is made through the breech and muzzle couplings. In the muzzle coupler lower barrel is fixed, with a gap to prevent thermal deformation. Combining trunks STP achieve a special adjustment nut with screw. Her turn on one click means the change of distance between the STP trunks of 7 mm at a distance of 100 m. During the rotation of the nut clockwise STP upper trunk moves upward relative to the bottom, counterclockwise – down relative to STP the bottom of the barrel.
  • In addition, the barrel with the drilling of the Lancaster equipped with adjustable sights: the front sight on the muzzle coupling can change the position vertically, and pillar – horizontal. The trunk complements the sighting strip of the type “dovetail” that allow you to install a rifle scope.
  • In models without the ejector sleeve is pushed by the ejector and removed by hand. In the shotgun with an ejector device ejects the fired cartridge case at the opening of the trunk. The ejector can be disabled by sliding the disconnector 90 degrees.
  • USM is mounted partly on its basis partially in the receiver, is provided with internal hooks. The strikers kept separate from Kurkov, is spring-loaded and fixed in the nest box. As battle used twisted cylindrical springs, ensuring reliability of the mechanism. Installed perehvatyvaet Kurkov, prevents accidental shot when the failure of the trigger or drop the gun, for example.
  • Automatic fuse is activated when you turn the lever it locks the sear when cocked the trigger. When the fuse is translated into “protection”, the sear will not lock. When opening the trunk the fuse automatically locks the sear.
  • In shotguns with a single trigger standard sequence is as follows: first fires the bottom barrel then the top. The order can be changed: this trigger is transferred forward until it clicks.

In guns with two trigger hooks have the ability unstressed descent Kurkov. This requires that you open the barrel, remove cartridges, place the safety button in forward position, hold down the triggers, close the trunks.

  • Stock and forend are made of walnut or beech. Sports models are equipped with rubber recoil pad.
Picking and packing

Standard rifle is simple:

  • cardboard box;
  • passport gun.

Some models can be supplied with the receiver block with the drilling of Lancaster. In this case, the kit also will include a special key.

The principle of operation

Mr-27M – line vertical double-barreled shotguns with some changes in design, but with a common principle of action. Gun designed to fire cartridges with plastic, metallic and paper shells, and bullets with a diameter of 0.2–0.3 mm smaller than the diameter of the receiver channel. Use caliber bullet made of hard materials – steel, brass, prohibited.

All models involve the use of lead shot. For steel made special modifications on the barrels which are marked “Steel shot”. The same applies to muzzle contractions: those that can be used for shooting steel shot, have a mark of “STEEL”.

Rifle with a chamber length of 70 mm allows the use of cartridges of any kind, except those that are marked “Max.1050 bar”. Gun with chamber length 76 mm involves the use of such a cartridge, that is, for models that are tested under pressure 1320 bar.

For firing the guns with the drilling of the Lancaster recommended ammo type “at gualandi”, “Brenneke”, “Sabot Slug”. Ammo 20 gauge, loaded with buckshot, use any.

  • Shooting is performed sequentially according to the standard scheme or change of priority. If the charge rifle is held after one shot, eat man world out there, it is recommended to place the cartridge into the cartridge chamber of the barrel, which is already shot, and the second to discharge the gun, which shoots the second.
  • Possible “long” shot due to slow response of the capsule. If pressing the trigger shot did not happen, is to hold the rifle in the direction to the goal for another 30-40 seconds and only after that to recharge.
  • Shift operation of muzzle of the contractions is performed traditionally: the nozzle is screwed into the barrel until it stops at the end of the ledge in the receiver channel, wherein between the end face of the barrel and the cylindrical portion of the contractions should be a gap. With the muzzle attachment should be flush or slightly recessed.
  • Tightening muzzle constriction is checked every 50-100 shots. Be sure before firing checked the visual integrity of the ring, which is formed on the junction narrowing and protrusion in the channel.
  • Charge rifle is usually: turn the right release lever until it stops, turn down the trunks. Then, in the cartridge chamber alternately put the ammo and guns return to the starting position. Release lever when it is in the center relative to the shank of the box. If not, the lever is adjusted manually.
  • Before firing, the fuse was transferred to the position of “fire.” Doing it at the last moment, when the rifle is aimed.
Disassembly

Maintenance – cleaning and lubrication require only a partial disassembly. Scheme of it is this:

  • pulled down the latch of the forearm on its lower surface and, while holding it, rotate the forearm away from the barrels;
  • disconnect the shank;
  • turn the right release lever is at the top of the box;
  • turn down to the limit of the guns and take them from the box;
  • Unscrew the screw head and remove it;
  • Unscrew the screw fixing the trigger guard. Then turn the bracket counterclockwise to detach from the larvae;
  • Unscrew the screw that goes through the butt, and then lightly tap the box on the tree shaking attachment of the butt with the box;
  • take off the butt.

In models with decorative patch boards before disconnecting the butt, you need to remove the screws securing the Board and remove them.

Complete disassembly, in addition to these operations includes the disassembly of the trigger locking mechanism and the ejection mechanism. Complete disassembly provides only for repair.

Assembling the rifle in the reverse order.

Keep the gun disassembled, but the fore end is attached to the trunks.

Tuning

Simple design does not give much space for change. Possible replacement stock for decorative purposes – made of other wood, with ornamental carving. When bundling strap of the type “dovetail” is possible to install an optical sight.
