Description of carabiner SM-2КО

Carbine chambered ring ignition of calibre .22LR. The longitudinally-sliding. Trunk thick-walled, match, on the muzzle chamfer is arranged in a funnel.

The transition from the category of sporting arms in hunting accompanied by the device of the mine shop, change the ergonomics of the Lodge and the device on the top edge of the receiver two longitudinal recesses forming the likeness of the strap dovetail.

Advantages and disadvantages

Very simple design, in which simply nothing to break.

  • Trunk with good internal ballistics, allowing confidently hit targets at distances up to 100 meters. However, it is worth noting that the bullet cartridge caliber .22LR has low initial velocity, causing the trajectory of its flight is close to ballistic. Moreover, it is greatly affected by wind. So this weapon is more suitable for sport or target practice at a shooting range. In the field a distance of 50 meters can be considered marginal.
  • The shutter has no lugs. This simplifies the design and makes the recycling process easier – one less thing to jamming in the slots. However, among fans of small calibre, there is no consensus about the adequacy of the locking handles are just laying in the groove of the receiver. For example, the closures rifles CZ-452 has three lugs, which is clearly excessive. It seems that the disdain for “toy” ammunition is not the correct way of thinking.
  • The shutter is removed from the receiver after pressing the trigger, approximately the same as the Mosin rifle. Therefore, it is possible his loss at long transitions. A high probability of such an event proved practical cases with the red army, the most experienced of which this part of the rifle kept in his pocket.
  • The force on the trigger is not adjustable, it is always the same, about a kilogram. Consider whether this is a disadvantage or advantage – a private affair of each arrow. But it is possible to adjust the stroke length in the range from 2 to 4 mm, which allows the operator to adjust the arms in accordance with his temperament or character hunting.
  • Undercut, forming the bar of the “dovetail” is not the best solution for mounting optical devices. If the scope is too massive, then it will stay without proper reliability.
  • Shop carabiner made of plastic, which is a modern fashion trend, but is not supported by most adherents of classical design weapons of metal and wood. Besides, he hangs out in the mine and for the elimination of this incident have to podmahivat tape. The magazine capacity to 10 rounds is clearly unnecessary, he’s too outside the box that hunting can be a cause of loss, breakage and other troubles.
  • In the bottom of the butt is arranged in the cavity for storing spare magazines. It’s a good idea, although heavier gun, the weight of which is quite large: 3 pounds for “no big thing” is excessive.
