Air Rifles Product

Here is the following air rifles product categories we sell:
  • PCP   ( 9 Articles )

    Pre-charged pneumatic (PCP) air rifle

    Pre-charged pneumatic (PCP) air rifle are usually filled by decanting from an air reservoir, such as a diving cylinder or by charging directly with a high pressure hand pump.
    PCP air rifle have very low recoil and can fire as many shots per charge. The ready supply of gas, has allowed the development of semi-automatic PCP air rifle. PCP air rifle are very popular in the world because of their accuracy and ease of shooting. They are widely utilized in 10 metere air rifle shooting events and the sport of Field Target shooting.

    During the discharge cycle, the hammer of the rifle is released by the sear to strike the valve. The hammer may move rearwards or forwards, unlike firearms where the hammer almost always moves forward. Prior to being struck by the hammer, the valve is held closed by a spring and the pressure of the air in the air gun's tank. The pressure of the spring is constant, and the pressure of the air changes with each successive shot. As a result, when the tank pressure is at its peak, the valve permits passage of less total volume of air than when the tank pressure has been reduced by a series of shots. This results in a somewhat greater consistency of velocity from shot to shot than would otherwise be expected, and accuracy with a rifle is mainly dependent on consistency.

  • PUMP   ( 6 Articles )
    Multi Pump Pneumatic Rifle
     
    Pneumatic air rifle utilize pre-compressed air as the source of energy to propel the projectile. Single-stroke and multi-stroke rifle utilize an on board pump to pressurize the air in their  reservoir.

    Multi-Stroke pneumatic air rifle  require 2-10 pumps of an on-board lever to store compressed air within the air rifle. Variable power can be achieved through this process, as the user can adapt the power level for long, or short-range shooting.
     
  • Spring Power - Break Barell   ( 4 Articles )
    Spring-piston Air Rifle
     
    Spring-piston air rifle are able to achieve muzzle velocities near the speed of sound from a single stroke of a cocking lever or the barrel itself. The difficulty of the cocking stroke is usually related to the power of the rifle, with higher muzzle velocities requiring greater effort.

    Spring-piston rifle operate by means of a coiled steel spring-loaded piston contained within a compression chamber, and separate from the barrel. Cocking the rifle causes the piston assembly to compress the spring until a small hook on the rear of the piston engages the sear; pulling the trigger releases the sear and allows the spring to decompress, pushing the piston forward, thereby compressing the air in the chamber directly behind the pellet. Once the air pressure has risen enough to overcome any static friction and/or barrel restriction holding the pellet, the pellet moves forward, propelled by an expanding column of air.

    Spring-piston guns have a practical upper limit of 1200 ft/s (370 m/s) for .177 cal (4.5 mm) pellets. Higher velocities cause unstable pellet flight and loss of accuracy. Drag increases rapidly as pellets are pushed past the speed of sound, so it is generally better to increase pellet weight to keep velocities subsonic in high-powered rifle. Many shooters have found that velocities in the 800 - 900ft/s (270/s) range offer an ideal balance between power and pellet stability.
    Spring rifle are typically cocked by a mechanism requiring the rifle to be hinged at the mid-point (called a break barrel), with the barrel serving as a cocking lever. Other systems that are used include side levers, under-barrel levers.

  • Accessories   ( 6 Articles )

    Early suppressors were created around the beginning of the 20th century by several inventors. The muffler for internal combustion engines was developed in parallel with the firearm suppressor using many of the same techniques to provide quieter-running engines. Indeed, automobiles mufflers are still referred to as silencers. The term silencer has since fallen out of favor among the firearms industry, being replaced with the more politically-correct term sound suppressor or suppressor. Common usage language favor the historically earlier term, silencer, firearm muffler and firearm silencer are synonymous.
    We also have some silencer or called suppressors for our De Pyra Air Rifles, but also Muzzle Brake.
    Our Muzzle Brake is precision-turned from the finest aircraft-grade aluminum, then given a tough, anodized, matte black finish, for guards the critical crown are from damage in case the rifle is dropped or banged against a hard object. You can found built in muzzle brake in several our air rifles product type.
    De Pyra Air Rifles has some air rifles accessories you'll ever need. Scuba Tank for filling high pressure air to PCP Air Rifles, PCP Regulator that you must attached to transfer high pressure air from scuba tank to the PCP Air Rifles, Rifles Wrist Band which we have it made from leather and synthetic leather, Muzzle Break Silencers, and you can keep your air rifles in Rifles Soft Case. Also if you consider to take the Rifles Scope to replace using Front Sight and Rear Sight that already fit on your air rifles, we have some Rifles Scope stock.
